The volume of the VAZ 2114 engine and its characteristics changed and improved throughout the entire production period, from 2001 to December 2013. The first batch was equipped with 8-valve injection units with a volume of 1.5 liters. After the modernization of 2007, new engines with a volume of 1.6 liters were installed on the "fourteenths". New serial engines VAZ-11183-1000260 received the 3rd class of environmental friendliness, Euro-3.

The most powerful of all VAZ units was assembled and installed on the Lada Priora in 2010. The power of this power plant was 98 horse power... A common feature of all VAZ 2114 engines is that they are 4-stroke, they have the same distributed fuel injection system. Fuel is supplied to the engine cylinders thanks to the installed injectors.

Today, this method of feeding engines is the most efficient of all fuel delivery schemes. The motors have a standard, orderly look, and their camshaft is on top. A closed-type liquid system is used to cool the units. Some of the mechanisms are lubricated with oil under pressure, some by splashing oil.

Characteristics of VAZ 2114 engines

A very common engine model on the VAZ 2114 was an engine with a total capacity of 81.6 liters. from. with the serial number VAZ 21114. This is an in-line type of power plant using injection system nutrition. The cylinder block is made of cast iron. Rotation frequency power unit reaches 5200 rpm. For high-quality operation, the engine is filled with AI-95 gasoline.

Unlike its predecessor (VAZ 2111), in the updated VAZ 21114, due to the installation of an improved crank and an increase in the stroke of the piston system, the engine volume increased by 0.1 liters. The total volume of the VAZ 21114 engine was 1.6 liters. In addition, it has become much more powerful. The downside of the increase in volume was the decrease in torque.

The piston stroke of such a motor on a VAZ 2114 reaches 71 mm. The size of the cylinder diameter is 82 mm. The volume of the engine varies from 1499 to 2114 cm³. Torque - 116 Nm / 3000 rpm. Fuel consumption in the city reaches 8.8 liters, on the highway it is much lower - 5.7 liters per 100 km. Oil consumption - 50 g / 1000 km. Engine weight 2114 - 127 kg.

The resource of the unit according to the factory data is 150 thousand km, in fact - up to 250 thousand km. Definitely, the VAZ 2114 will not suit adrenaline seekers and fans of driving on the track. This option is perfect for business, confident people. The car will perfectly cope with the need to transport heavy trailers and more.

If you want to have a faster version, it is better to opt for the 1.5-liter VAZ 2111 engine. The reduced stroke of the piston system allows the engine to gain momentum faster.

Selecting the number of engine valves

The selection of the engine largely depends on the number of valves installed. Early models of the VAZ 2114 differed in engines with 8 valves. After 2007, the eight-valve engines were replaced by motors with 16-valve heads. Engine valves internal combustion are used for the intake of the air-fuel mixture and the release of the exhaust gases. Accordingly, the higher the valve capacity, the stronger and more powerful the motor.

It is easy to conclude that the gas throughput through a head with 8 valves is much lower than through a 16-valve one. Despite the fact that 8-valve engines do not perform well at high frequencies, they give excellent performance at low rpm thrust.

16-valve engine

A 16-valve engine can allow more gas to pass through it, making the car accelerate faster. Alas, this design also has drawbacks, the main of which is the deformation of the valves themselves. 16-valve engines have not yet stood the test of time, so eight-valve engines are still considered more reliable.

When choosing an engine for a VAZ 2114 car, you need to be guided by the following principles. 16-valve engine (1.6 L) or 8-valve (1.5 L) select if required high speed and great torque. With an emphasis on stable and powerful traction at low revs, an 8-valve 1.6-liter engine is the best option.

Causes and repair of motor malfunction

As already mentioned, according to AvtoVAZ, the maximum service life of a VAZ 2114 engine is 150 thousand km. With normal and timely maintenance, the motor can run even more. The standard operating temperature range is from 95 to 103 ° C. The oil change should take place on a warm VAZ 2114 engine every 10-15 thousand km. When the first signals of a car malfunction appear, you must contact the station or find the cause yourself. Most common engine problems.

1. Floating engine speed. As a rule, this happens in new cars and when idle... If the car has no run - go for diagnostics, repairs must be made under warranty. The cause of the problem may be an idle speed regulator, a throttle position sensor or a vacuum apparatus.
2. The car engine stalls on the move (floating engine speed plus problems with the mass air flow sensor) - the reasons for the breakdown are the same.
3. Rough engine operation (troit). Cylinder compression measurements should be taken. If one of them has low compression, then the valve or the head has burned out. If the difference in measurements is small, then the pressure in the valves should be adjusted or the gasket replaced. If the compression measurements showed no deviations, then you need to check the ignition module.
4. The engine does not reach normal operating temperature. The reason lies in a faulty thermostat.
5. Engine noises and tapping. Poor valve alignment is usually the cause. If the sounds amplify when you press the gas pedal, you need to go to a specialist. Problems can arise in connecting rod or crankshaft bearings, or in cylinder pistons.

Various sensors and controllers are used in vehicles to ensure proper operation of the engine and key components. They allow you to monitor the status of systems important to the machine. In this article, we will analyze the main 2114 injector 8 valves, their location and purpose.

List of all regulators

Icon Check Engine under the alarm - indicates a malfunction in the motor

All sensors in domestic "four" are installed in engine compartment, on the body, wiring diagrams, as well as on the gearbox. Almost all controllers are installed on the car during production, but some of them can be installed additionally.

The entire list of devices that are in the VAZ 2114 is given below:

• engine fluid pressure;
• coolant temperature;
• the level of antifreeze in the system;
• fuel level in the gas tank;
• IAC - idle speed regulator;
• DMRV - mass air flow;
• brake fluid level in the system;
• ДПДЗ - throttle position;
• movement speed;
• DPKV - crankshaft position;
• DPRV, aka camshaft position sensor or phase sensor;
• lambda probe;
• detonation;
• uneven road surface;
• outside air temperature (video by Ivan Vasilievich).

Location and purpose of devices

What sensors are used on the VAZ 2114, we figured it out. But if you are repairing your "iron horse" yourself, then you will probably be interested to know where the main controllers are located.

Where are the VAZ 2114 sensors located and what functions are performed:

1. Engine fluid pressure controller. This element allows you to calculate insufficient pressure consumable in the power unit. If on dashboard the corresponding icon began to light up, this may indicate problems and malfunctions that have appeared in the operation of the motor. In the event that the indicator on the tidy has been on for a long time, and the car owner does not take any action to repair his vehicle, this can lead to serious problems. For example, you will either have to do a major overhaul of the power unit, and if the situation is more complicated, then it will need to be replaced altogether.
   It should be noted that the indicator on the tidy may appear in several cases - when the level of consumables in the system decreases, when the filter element is clogged, when the oil pump breaks down, as well as in case of wiring faults. If the level of the engine fluid has dropped very much, then it is possible that the problem lies in the leak, therefore it is necessary to find all the places of leakage and eliminate them. Perhaps the indicator appeared on the tidy as a result of its failure. The location may vary depending on the engine type. For example, on 8 valve motors, the controller is installed to the right and below the valve cover, in the block head. If we are talking about a 16-valve unit, then the meter is placed on the left end of the camshaft bearing housing. It should be borne in mind that if the regulator breaks down, it will be more expedient to replace it with a new one.
2. The controller is the temperature of antifreeze in the cooling system, this regulator is also called a motor temperature sensor. This device is located on the intake manifold of the so-called cylinder head cooling jacket. In accordance with the signal from the device, information about the temperature state of the power unit is displayed on the dashboard. Thanks to him, the car enthusiast will be able to know to what temperature the engine has warmed up, and this data is extremely important, especially when the power unit overheats.
   As for checking the device, diagnostics can be done at home. To do this, it is necessary to connect a multimeter to the mechanism and switch it to the ohmmeter operating mode, and put the controller itself in a vessel with antifreeze. Further, the container heats up, and in accordance with the temperature change, the resistance is diagnosed. If these data correspond (for a detailed table, see service book), then DTOZH is operational.
3. Antifreeze level meter in the cooling system. As the name implies, this device allows you to determine the volume of the remaining consumable, so that if there is a lack of it, the car owner could supplement the volume. The meter is mounted in an expansion tank with a consumable liquid and it is equipped with a thread, so it is screwed into the installation site, and power is connected to its end.
4. Brake fluid level meter in the system. From the name it is clear why it is needed, because the operation of a car with low level "Brakes" can lead to tragic consequences. By itself, it is a float-type controller that is mounted in expansion tank with consumables.
5. IAC or idle speed regulator. This element is designed to ensure stable idle speed, it lets air into the power unit at idle speed bypassing the throttle position sensor. If the device fails, idle will float. The part is mounted directly on the throttle, next to its damper.
6. Mass air flow sensor - of all the regulators, this is the most expensive device in terms of cost. Using this controller, the control unit allows you to determine the volume of consumed air, as well as adjust the ratio of air and fuel to form a combustible mixture. The latter is subsequently fed to the motor nozzles. If the unit fails, this can lead to a decrease in engine power, as well as problems in the operation of the engine at idle speed. The part is mounted on the body of the air filter element, near the intake manifold.
7. Speeds. Mounted on the gearbox, it allows the driver to track the speed at which the vehicle is moving.
8. Fuel level in the tank. The float-type device is located in the "four" gas tank. If it breaks down, the amount of fuel will be displayed incorrectly on the dashboard.
9. TPS is a unit that functions in tandem with an idle speed regulator, it is also called a gas pedal position sensor. This part allows you to determine the degree of throttle opening. If it breaks down, the engine will not respond to pressing the gas pedal, and the engine speed may also increase arbitrarily. The mechanism is located directly on the throttle.
10. DPKV is designed to synchronize the control unit and the car engine. It is located near the generator drive pulley.
11. DPRV, used to determine the phased injection, is installed on the side of the air filter element, in the vicinity of the block head cover. In accordance with the position of the camshaft, the regulator sends a signal to the control unit, as a result of which injection is carried out before the valve opens. The fuel is thrown in simultaneously with the air flow.
12. Lambda probe or. The regulator allows you to determine the amount of oxygen that is in the exhaust system, as well as adjust the combustible mixture. Installed in the intake manifold, next to the resonator. The device transmits an impulse to the control side about the volume of oxygen concentration in the exhaust gases.
13. Detonation. The device detects vibrations in the operation of the power unit and automatically adjusts the ignition angle. In "fours" this part is mounted by cylinders 2 and 3, from the fan side.

Malfunctions

As for the faults, they can all be divided into several groups:

1. Breakdown of the device. In this case, the problem will be solved by replacing or repairing it.
2. Broken wire. The malfunction is solved by replacing the wire.
3. Bad contact. The contact is either cleaned from oxidation or changed to a new one.

Video "Replacing IAC at home"

Detailed instructions on how to replace the idle speed controller with your own hands are shown in the video below (the author is the channel In Sandro's garage).

The appearance in the production of AvtoVAZ of the Samara family (originally Sputnik) was a real breakthrough for the domestic automotive industry of that time. Debuted in 1984 three-door hatchback VAZ-2108, made a splash among Soviet motorists. Stylish design, advanced technologies in production, outstanding driving performance - all this led to a resounding success. And this despite the fact that the body of the three-door hatchback clearly did not correspond to the utilitarian preferences of motorists of the time. The new model gained immense popularity, and its design for its characteristic silhouette even received its own nickname - "chisel".

In 1987, the model 2109 was released - a five-door hatchback based on the "eight". While maintaining all its advantages and chips, she was more suitable but the role family car... This only consolidated the success. In the future, the family was replenished with a four-door sedan. With minor changes, the first generation lasted on the assembly line until 2004.

The second generation of the Samara-2 family is, in fact, a restyling of the first generation models. The front part of the body was redesigned, lighting technology and some visual elements of the exterior design were changed. The interior also received changes in the form of a new panel (the so-called "Euro-panel"), as well as improvements to some elements.

The line of power units VAZ-2114 (Samara-2)

During the production period, various modifications of motors already known from other models of the manufacturer were installed on the model of the Samara-2 family. The widest choice was offered by the model 2114 - the heir to the legendary "nine" VAZ-2109.

All motors, which were equipped with "fourteenth", are in-line atmospheric fours. The carburetor power system is gradually becoming a thing of the past, so the restyled successor of the “nine” is found exclusively in injection versions. This made it possible to modernize the engines and comply with environmental standards.

• 1.5 l. 8 cl. (77 hp) - index 2111;
• 1.6 l. 8 cl. (81 hp) - index 21114/11183;
• 1.6 l. 16 cl. (89 hp) - index 21124;
• 1.6 l. 16 cl. (98 hp) - index 21126.

Engine 2111 (1.5 l., 8 valves)

At its core, the engine is a revised modification of the well-known unit 21083, which appeared on the legendary "eight". The revisions concerned, first of all, the power supply system. Instead carburetor system the motor was equipped with an injection. The design of the connecting rod and camshaft... All this made it possible to improve the performance indicators. Power and torque have increased. In addition, the engine became compliant with Euro-2 environmental standards.

Overhead camshaft and belt driven gas distribution mechanism. Its nice feature is that if the belt breaks, the valve is not subject to damage.

Typical problems

Floating idle speed most often occurs due to the failure of such components:

• Idling regulator;
• Position sensor throttle;
• Vacuum amplifier.

If to the existing symptoms is added the fact that the engine stalls on the move, then you should also pay attention to the condition of the mass air flow sensor (MAF).

If the engine began to work unevenly and "triple", then first of all you should pay attention to the compression indicators. A noticeably less compression in one of the cylinders most likely indicates a burned-out valve. If the spread is small or is present in several cylinders, then the valve clearances should be checked. It is highly likely that they require adjustment. A similar symptom may indicate problems with the gasket between the cylinder head and the cylinder block. However, even if such symptoms are not observed, do not forget about regularly checking the thermal clearances of the valves, as well as adjusting them. The manufacturer recommends performing such a check every 20 thousand km. If everything is in order with the compression, but there are similar symptoms, it is necessary to check the ignition module.

Often noises and knocks become satellites of this motor. All this can be the cause of unregulated valves. If you hear an increasing loud, dull metallic sound when you press the gas pedal, you will most likely need to repair the engine. There are several main reasons for this symptom:

• Knocking of main bearings;
• Knocking of connecting rod bearings;
• The clatter of pistons.

The operating temperature range of the coolant for this unit is 95-103 degrees. Nevertheless, it is not uncommon for the engine to simply not heat up to such indicators. The main reason for this behavior of the motor is thermostat malfunction. Some owners have to replace it almost on a regular basis. All this is a consequence of the poor quality of spare parts.

Other encountered malfunctions of this engine

• Valve cover leaks;
• Wear of components of the cooling system;
• Failures of the injection system on old copies;
• Breaking of the reception fasteners exhaust pipe (it is treated by replacing steel threaded connections with brass ones).

The engine is very common and deservedly popular with many motorists. Its simplicity, maintainability and good knowledge makes it easy to cope with existing shortcomings and typical malfunctions.

The manufacturer officially declares a resource of 150 thousand km. However, practice shows that many specimens are nursed deeply over 200 thousand km. Much depends on operating conditions and attention to maintenance.

Engine 21114/11183 (1.6 l. 8 cl.)

The unit is a continuation of the development of the 2114 engine, and, accordingly, its progenitor 21083, which was installed on the first generation of the Sputnik / Samara family. The changes mainly affected the cylinder block. Its height has increased, and, accordingly, the piston stroke. The working volume has increased to 1.6 liters. Performance characteristics in terms of power and torque have also increased. In practice, this manifests itself in the form of improved elasticity and greater traction. The improvements made allowed the engine to comply with Euro-3 environmental standards.

Car owners may call this engine by different names. You can find such names as engine 2114 (out of habit with 8-valve Euro-2), "Kalina", as well as corresponding to the official indexes 21114 and 11183. The difference between engines with these two indexes is that they were produced on different conveyor lines.

The huge similarity with the 2111 engine gave this unit and problems and malfunctions that are almost identical to it. It is also necessary to regularly monitor the condition of the valves and to combat uneven operation.

From the unpleasant individual characteristics - noisy work similar to the sound of a diesel engine. The rest of the noise is the same as in the 2111 engine.

However, despite the common roots and problems, the masters note that 21114/11183 is still a little less capricious. At the same time, there is still no risk of bending the valve when the timing belt breaks.

Motors and resource indicators are similar. So, the manufacturer indicates 150 thousand km before overhaul, however, in practice, the indicators easily exceed 200 thousand km, and sometimes reach 300 thousand.

Engine 21124 (1.6 l., 16 valves)

The engine with the index 21124 replaced the 2112 unit on the conveyor. The sixteen-valve "four" increased the volume to 1.6 liters due to the use of a "high Kalinovsky" cylinder block. Improvements have been made to comply with Euro-3 environmental standards. Due to this, traction at low revs increased, but at the same time it became more relaxed in character. Compared to the "twelfth", the noise has increased.

The problem that was most feared by the owners of the last generation sixteen-valve with the index 2112 was solved. Due to the special design of the pistons with holes, if the timing belt breaks, the valves will not bend. This is a significant advantage over the "twelfth".

Due to the presence of hydraulic compensators, it is no longer necessary to constantly monitor the thermal clearances of the valves. However, these parts are most often the cause of unpleasant knocking from under the hood. In addition, the cause of knocking can be a problem with oil pressure. Moreover, the indicators can be either lower or higher than the norm.

Gone problem with valve adjustment was replaced by a new one. It is recommended to monitor the timing belt tension and tighten it every 15 thousand km.

There are also problems with knocks of a different nature. They can be called "branded" for VAZ engines. This is the knock of main and connecting rod bearings, as well as pistons.

The engine is not deprived of other "proprietary" faults:

• Floating revolutions;
• The engine is "troit";
• Stalls at idle or in motion;
• Temperature problems.

All these problems are familiar from other units. For example, for the same 2111. The roots of the problems are common, so the solutions can be found in the corresponding section of this article.

If the car does not start at all, then the check must be carried out according to the following scheme:

• Starter and battery;
• Ignition system;
• Power supply system and fuel pump.

In case of problems with traction, and specifically with its decrease, the pressure in the fuel rail should be checked, as well as the condition of the injectors. Their filters may be clogged.

Increased vibration has become a characteristic feature of the engine. There may be many reasons for this. Among them, the idle speed controller, high-voltage wires, candles, a lambda probe. And this is not a complete list. To identify the cause, you will need high-quality diagnostics from an experienced master.

Standard indicators of the resource from the manufacturer of 150 thousand km this engine easily overcomes. According to the experience of the owners, most of the specimens easily nurture more than 250 thousand km. In addition, in an unspoken rating, this engine model is considered one of the most successful at VAZ. This is especially true for owners who prefer to tune and modify the engine of their car.

Engine 21126 "Priora" (1.6 l., 16 cl.)

The continuation of the evolution of the VAZ 16-valve was a motor with an index of 21126. It is a development of 21124, but with some changes. Among them:

• Lightweight ShPG (connecting rod and piston group);
• Better surface treatment;
• Honing cylinders with more stringent requirements.

Timing drive - belt, with overhead camshafts. But unlike its predecessor, when it breaks, the valve bends. There is a radical solution to this design feature - piston replacement. If the engine is in a standard design, then you just need to carefully monitor the condition of the belt. Moreover, the problem with its weakening was solved by installing an automatic tensioner. The type of belt used was also changed.

Typical faults

If a loss of power is felt, then most often the reasons for this are in the following phenomena:

• Loss of compression due to a burnt cylinder head gasket;
• Cylinder wall wear;
• Worn piston rings;
• Burnout of the piston.

Erratic operation and failure to start may result in a pressure problem in the fuel system. In addition, such symptoms cause sensor malfunctions, air leaks through leaking hoses or their connections, timing problems, or problems with the throttle valve.

If the engine is clearly "troit", then, first of all, it is necessary to check the compression indicators in order to eliminate the problem with the valve burnout. But more often this is caused by faulty spark plugs or an inoperative ignition coil. Sometimes the reason lies in the condition of the injectors, namely in the degree of their pollution.

Floating revolutions are quite a typical disease of VAZ 16-valve valves. Often, in addition to this, the engine runs unevenly. In this case, first of all, it is necessary to check the mass air flow sensor (MAF). If it is serviceable, then most likely the reason is the throttle valve. It is necessary to clean it, and possibly replace the sensor of its position (TPS). At the same time, you should check the state of the idle speed regulator (IAC).

Not without this engine and without a "proprietary" headache with a thermostat. It also becomes the reason that the engine cannot warm up to operating temperature. However, if there are severe frosts outside, perhaps the old-fashioned way with a cardboard box in front of the radiator will help.

Some typical sores of other VAZ engines migrated to the 21126 Priora. So, if knocks are detected under the hood, first of all, you should check the condition of the hydraulic lifters. Most often, they are the culprits of unpleasant knocks. At the same time, knocks that are associated with main and connecting rod bearings, as well as pistons, familiar from other VAZ engines, can also occur. This is already a serious malfunction, which is fraught with complex engine repairs.

Minor problems, in the form of refusal to start, most often lie in the following faults:

• Starter and battery;
• Ignition coil;
• Candles;
• Fuel pump malfunctions;
• Hammered fuel filter;
• Defective fuel pressure regulator.

Having improved the performance indicators, the 21126 engine is still slightly inferior to its predecessor 21124 in reliability. Although it cannot be said that it is inferior very significantly. This is mainly due to the more complex design. Nevertheless, it is one of the best domestic engines, which also fits into modern environmental standards.

The declared resource is 200 thousand km. In comparison with the officially declared resources of predecessors, it has increased. In practice, however, older motors with a simpler design generally run longer. Judging by the feedback on actual operation, on average real resource corresponds to that specified by the manufacturer. Sometimes it can be more, sometimes less. Much depends on the operating conditions and service level.

13.04.2017

The car VAZ 2114 is popularly just a four, is a popular front-wheel drive five-door hatchback, released to replace the VAZ 2109. The car was released in 2001. It is a representative of the Samara 2 series, along with the three-door VAZ 2113 and the VAZ 2115 sedan. In fact, the VAZ 2114 is a restyling of the old nine. The exterior has become more modern, and the interior has also been updated. VAZ 2114 can be called a kind of "people's" car, as its popularity among the population was enormous. In the article we will consider the engines that were installed on the VAZ 2114, we will touch on their characteristics and disadvantages.

ENGINE 2114/2111

The VAZ 2111 engine, which is popularly called 2114, is generally the eighty-third engine. However, unlike 21083, 2114 uses an injector, not a carburetor. In addition, the 2114 is characterized by a floating connecting rod pin and a different camshaft. Finally, the 2114 has more power. Engine VAZ 2114 1.5 liters. inline, injection, with four cylinders, has an overhead camshaft, a belt is used in the timing drive. In this case, when the belt breaks, the valve engine does not bend.

ENGINE DISADVANTAGES

As for the disadvantages, the following are noted. Valves need to be adjusted, parts of the cooling system wear out quickly, frequent replacement is required oil filter, problems with the valve cover sealing, fuel pump and a distributor sensor. The downstream exhaust pipe mountings may break as steel nuts are used instead of brass.

In addition, revolutions often begin to float. The engine can be triple. Often, the engine will not warm up to the correct operating temperature. The problem is most likely the thermostat. In addition, the engine can knock and make noise, usually due to unregulated valves.

ENGINE VAZ 11183/21114

The 21114 engine, which has a second index of 11183, is a development of the ideas laid down by the 1.5 liter 2111 power unit. and directly, 083 motor. The engine has a taller block of cylinders, an increased piston stroke, and a volume of 1.6 liters. The engine has improved environmental performance and greater reliability.

Compared to the VAZ 2111 engines, the VAZ 11183 unit is less capricious, more elastic and pulls. If we compare these two engines, it should be noted that they are assembled even at the same plant, but on different lines. It is an in-line, injector-type, four-cylinder engine with an overhead camshaft. The timing belt uses a belt. If it breaks, the valve engine does not bend, however, in the presence of an evil sports camshaft, the risk of a problem outcome is possible.

ENGINE DISADVANTAGES

The engine has the following weak sides... The need to timely adjust the valve. The engine can make noise and diesel, in general it should be noted that the engine is quite noisy, a variety of extraneous sounds and knocks for it, this is the norm. Finally, the engine is characterized by tripping, overheating or, on the contrary, problems with warming up to an operating state.

ENGINE VAZ 21124

AvtoVAZ, as part of the development of 16 valve engines, in 2004 replaced the VAZ 2112 engine with a 124 power unit. A higher block from Kalina was used on it, the piston stroke was also increased, having received a working volume of 1.6 liters. Having adapted the 124 engine to Euro-3 standards, we increased its environmental performance. In addition, there is now traction at the bottom, and a quieter engine operation is noted.

The 21124 1.6 liter engine is an in-line engine, injection-type with four cylinders and has an overhead camshaft. The timing belt uses a belt. When it breaks, the engine does not bend the valve, thanks to special holes. According to official data, the 21124 engine has a resource of 150 thousand km, while in practice it reaches 200-250 thousand km.

ENGINE DISADVANTAGES

First of all, it is necessary to note the requirement to regularly tighten the timing belt. In addition, the engine is characterized by tripping, knocking and noise during operation. Also, the engine is prone to overheating. Despite these shortcomings, according to the owners, the VAZ 21124 engine can be called one of the best power units from the VAZ.

ENGINE VAZ21126

The 21126 engine is a continuation of the VAZ 21124 power unit, which has a 39% lighter ShPG from Federal Mogul. This is an engine with reduced valve holes, and a timing belt that has an automatic tensioner. Due to this, the problem of timely belt tensioning has disappeared.

In the part of the block, we have a better surface treatment, high requirements for honing cylinders to Federal Mogul standards. VAZ 21126 1.6 l. is an in-line engine of an injection type, it has four cylinders and an overhead camshaft. In general, the engine is considered good, especially for the city.

ENGINE DISADVANTAGES

Owners note uneven work, loss of engine power. In addition, the timing belt is not particularly reliable. The uneven operation of the engine can be caused by problems with fuel pressure, a malfunction of the timing belt, malfunctioning sensors, air leaks through the hoses, or a malfunction of the throttle valve. In the event of a loss of power, the cause must be sought in low cylinder compression, wear of cylinders, piston rings, and piston burnout. If the timing belt breaks, the engine can bend the valves. The problem is solved by replacing the standard pistons with jointless ones.

In the United States, large-scale problems began with the Nissan Rogue and Rogue Sport crossovers, in which the emergency stop system is falsely triggered.

The US National Highway Administration reported having accepted 88 complaints about Nissan vehicles in the past month. In the period from the beginning of January to August of this year, 844 cases of unreasonable operation of the emergency system were registered. 14 incidents led to serious accidents, during which more than 5 people were injured.

The problem cars are Nissan Rogue and Rogue Sport from 2017 and 2018, which came with an emergency stop system. Contacting the road service, they ask to force nissan recall defective vehicles from the United States, which number 554,673 and are regarded as potentially dangerous.

In turn, Nissan offers to carry out a firmware update at service centers in the United States, but there is no guarantee that this will help solve the problem. A year earlier, the brand was doing massive service repairs to Rogue and Rogue Sport due to a similar situation in Canada. A similar problem affected 76,341 vehicles.

Will the software update help - time will tell.

The production of the Mitsubishi Xpander minivan will be organized at one of the enterprises located in Vietnam. The Mitsubishi Outlander is currently being produced at this facility.

Xpander is currently produced in a single facility. The car plant is located in Indonesia. Vietnamese production capacity will be able to release the first minivan in 2020. The decision to open the production of such cars in Vietnam is largely due to the increased demand for Xpander in this country. About 14 thousand Mitsubishi Xpander were purchased last year. Market passenger cars Vietnam has only about 600 thousand vehicles. Against this background, the demand for minivans looks encouraging.

The car appeared on the world market in 2017. This is a minivan with crossover elements. The car can accommodate 7 people, including the driver. The chairs are arranged in three rows. The Mitsubishi Xpander has a 104 horsepower gasoline power plant in its arsenal. Engine capacity is 1.5 liters.

The car was developed specifically for sale in the markets of Southeast Asia, as well as in third world countries. It should be admitted that the Japanese automaker accurately calculated the conjuncture, the model is in high demand in this region. Therefore, the organization of the production of such machines in Vietnam should be economically profitable.

The entire route of the new bus is 900 meters, the vehicle passes it 16 times per day. The drone runs from 10 am to 4 pm, at this time there are no traffic jams.

The test will only end on October 14th. Until then, there will be one driver in the cockpit who will take over if required.

If the drone tests are successful, Sotetsu Bus will prepare a whole series of buses that will have the fourth level of autonomy. This means that the vehicle does not require a driver, even for safety net.

The new line of buses will operate on regular routes and will be used all the time, regardless of the traffic situation. But travel by transport will also be paid.

In order to independently repair a VAZ-2114 with an 8-valve injector, you need to know the structure and principle of the engine. With this knowledge, it is possible to establish the cause of a malfunction without resorting to outside assistance.

The VAZ series engines are equipped with a distributed fuel injection system, which improves the driving performance, and typically reduces the percentage of toxins in the exhaust gases. There are two types of fuel injection systems: with feedback, as well as without it, they may differ in details. It all depends on the export or import of products.

Injection feedback is commonly used in overseas machine models and is equipped with a neutralizer. The open loop system (sold domestically) includes a CO potentiometer that adjusts the flue gas.

Neutralizer

The vehicle is equipped with a neutralizer to change toxic elements and convert them into toxin-free components. Its location is the exhaust system, directly behind the muffler pipe.

For the high-quality functioning of this unit, it is necessary that the mixture supplied to the engine contains a certain proportion of air and fuel. This is due to electronic system injection, which controls the distribution of fuel based on the efficiency of the load on the internal combustion engine.

Electronic control unit

This unit monitors the information from the sensors and is responsible for controlling the fuel injection system.

The control unit contains a diagnostic system that recognizes a system failure. It signals about all malfunctions occurring in the system through a light located on the dashboard - Check Engine. It also stores any errors that have ever occurred. Subsequently, their codes help to understand when diagnosing problems.

Memory

The ECU has three types of memory. RAM is a kind of notebook. All temporary data is entered into it. The RAM microprocessor is located on the ECU board. To save all the incoming information, he needs an uninterrupted supply of voltage.

ROM is an energy independent memory that stores all data. The EPROM contains the sequence of all the actions performed.

Sensors

The temperature sensor is a small thermostat in the cylinder head pipe, with its help the temperature indicator of the antifreeze is monitored.

The knock sensor is screwed into the cylinder block and detects detonating phenomena occurring in the engine. In the event of the slightest vibration in the motor, an impulse is transmitted to it. After that, according to a signal from the control unit, the ignition is corrected, during which unwanted flashes of fuel are eliminated, leading to the appearance of knocking.

The oxygen level sensor is installed in a closed loop system. Its attachment point is in front of the muffler. The normal temperature indicator reaches 360 degrees, and a special heating element is provided for active heating of the motor.

The air flow sensor is mounted close to the air filter. It consists of three elements, one of them determines the ambient temperature, while the rest are needed to maintain a certain temperature level higher than the first. The air flow cools all heating elements, and the ECU uses this information to determine the air flow rate and sets the opening or closing times of the injectors.

The location of the CO-potentiometer is the engine compartment (the wall of the air intake box). This element sends a signal to the ECU used to adjust the required proportion of air and fuel.

The vehicle speed sensor is located near the dipstick engine oil... Through it, a signal is sent to the ECU similar to the speed of the driving wheels.

Synchronization Sensor - Located on the oil pump cover near the generator drive pulley. According to the information coming from it, the control unit calculates the crankshaft speed and then sends a characteristic signal to the injectors.

Supply system

The air filter is located at the front of the engine and is equipped with rubber fixing elements. If it becomes necessary to replace them, the corrugation is located on the same parallel with the center line of the car. The main function of the throttle pipe is determined by the metering of the air flow entering the intake pipe. The air that enters the engine is corrected by the throttle valve, which is connected to the accelerator pedal. The throttle body consists of two parts: the throttle position sensor and the idle speed regulator.

Fuel system

It consists of many components: a gas pump, a fuel pressure regulator, a fuel filter, a fuel line, injectors and a rail, through which the fuel enters the engine. The ramp - the bar on which the injectors and the fuel pressure regulator are located, is attached with two bolts to the intake pipe. The injectors are fixed to the fuel rail, its function is to supply fuel to the engine. The nozzle is a solenoid valve that opens and sprays fuel in a thin stream under pressure after a corresponding impulse from the ECU is applied to it. On contact with the heaters, the fuel evaporates and is fed through the needle pin into the combustion chamber.

In 2001, the line of VAZ cars was replenished with a five-door hatchback, popularly called "four". The VAZ 2114 engine was repeatedly modified and refined.

In different years of production, the car was equipped with eight-valve engines of 1.5 liters and 1.6 liters.

Also, sixteen-valve internal combustion engines with a volume of 1.6 liters were installed on the machines. The model was produced until 2013.

1.5і l

The main difference between the VAZ 2114 engine and the 21083 engine, on the basis of which it was developed, was the use of an injection-type injection system instead of an obsolete carburetor and a camshaft with changed phases. The connecting rods are attached to the pistons using a floating pin.

Installed on VAZ 2115, 21083, 21102, 21099, 21122, 2111, 2113, 21102, 21093.

1.6і l

Thanks to the increase in the cylinder block in height (2.3 mm), it was possible to increase the piston stroke and engine volume to 1.6 liters. The designers have achieved greater throttle response and improved environmental performance of the VAZ 2114 engine.

The car received an increase in power (81 hp and 125 Nm of torque), but lost in efficiency. Now consumption of AI 95 in the combined cycle is 7.6 l / 100 km.

The 1.6i engine was equipped with: VAZ 21112, 21101, 21121, 2113, 2115, Lada Granta and Lada Kalina.

16V 1.6і l VAZ 211440-24

The logical development of the Kalina motor was a sixteen-valve engine. VAZ 2114, equipped with a 124th engine, meets the environmental requirements of Euro-3.

The piston stroke and cylinder bore remained the same. Thanks to minor modifications, at 5 thousand rpm, the engine develops a maximum power of 89 liters. from. The combined cycle consumption was reduced to 7.5 liters. a hundred.

16V 1.6і (124) was also installed on the model: VAZ 21124, 21123 Coupe, 21104, 21114.

16V 1.6і l VAZ 211440-26

ICE 21126, also known as the Priora motor, has received a number of significant improvements:

• lightweight connecting rod and piston group produced by Federal Mogul (39%);
• smaller valve wells;
• modified timing drive with automatic tension;
• better honing of cylinders;

Thanks to the above changes, the engine received an increase of 9 liters. from. and a peak torque of 145 Nm. In the combined cycle, "four" with 126 engines consumes 7.2 / 100 km.

16V 1.6і (126) also receives the Lada family (Priora, Kalina, Granta, Kalina of the second generation).

All modifications of the engine installed on the VAZ 2114 have a block cast from cast iron and a fuel injection system. Despite constructive decisions, used to improve dynamic and environmental performance, the device of the VAZ 2114 engine has retained its simplicity and moderate maintenance cost.

Operation and resource

An oil change should be done every 9-11 thousand km. Regardless of the modification, 3.2 liters are required to change the oil. Recommended viscosity: 5W-30, 10W-40, 5W-40, 15W-40.

According to the manufacturer, the service life of the motors is 150 thousand km. (200 thousand km for the Prior motor). Practice has shown that with proper maintenance, the motor is capable of covering up to 250 thousand km.

Failure to comply with maintenance standards and improper tuning of the VAZ 2114 engine significantly reduce its resource.

Features and disadvantages

• after the timing belt breaks, the valves remain unharmed;
• requires regular adjustment of valve clearances;
• wear of the cooling system components;
• snotty oil from under the valve cover;
• oil leak from under the ignition distributor and fuel pump;
• poor fastening of the exhaust manifold (solved by replacing steel nuts with brass ones);
• unreliability of early injection systems.

• Breaking the timing belt does not deform the valve;
• the need for periodic valve adjustment;
• increased noise and vibration.

• Thanks to the holes on the pistons, even with moderate sports shafts, when the timing belt breaks, the valve does not bend;
• every 15 thousand km you need to tighten the timing belt.

• a break in the timing belt leads to bending of the valves (the problem can be solved by installing plug-free pistons.

Popular faults

Due to the imperfect workmanship of the unit and a large number low-quality spare parts, the engine and attachments require increased attention.

Major problems and possible causes:

1. Unstable idling of the VAZ 2114, the engine stalls after starting. Reason - Coking of the idle speed regulator (IAC), the throttle position sensor, vacuum cleaner, unreliable signals from the mass air flow sensor "drizzle";
2. The start has worsened, the engine is troit - the reason may be: incorrect valve adjustment, lack of compression in one of the cylinders (possibly a valve has burnt out), wear of valve springs, air leakage (check the joints of hoses and nozzles coming after the mass air flow sensor and to the vacuum cleaner, valve hose absorber purge, tight fit of the injectors to the cylinder head), malfunction of the ignition module, spark plugs do not spark, inoperability high-voltage wires, incorrect valve timing (perhaps a timing belt slipped a few teeth);
3. The throttle response has disappeared and the VAZ 2114 engine does not pull. Breakdown is possible due to a malfunction of the ignition module (symptoms appear on a warm engine), clogged catalyst, the fuel pump does not create the required pressure, contaminated air filter, air leaks, carbon deposits on spark plugs, lack of compression;
4. Extraneous knocking, noise and vibration of the VAZ 2114 engine. Breakdown may appear because the valve clearances need to be adjusted, the valve springs sag, the seats sag, the crankshaft main bearings or connecting rod bearings are worn (it is possible that the pistons themselves are knocking), hydraulic compensators, engine mount wear (pillows);
5. Does not show the temperature of the engine VAZ 2114. It occurs due to a malfunction of the coolant temperature sensor (the sensor screwed into the cylinder head is responsible for the readings on the tidy), open circuit, oxidation of contacts, malfunction in the indicator on the dashboard;
6. The engine is warming up. Breakdown of the thermostat (liquid circulates only in the engine cooling jacket). When buying a thermostat, see the instructions for which working temperature engine it is calculated (for the engines under consideration it is 95-103 degrees); damage to the water pump impeller, malfunction of the fan switch on sensor, or the fan itself does not work.

The standard dynamics of the VAZ 2114 is not enough for many owners. Tuning the engine allows you to improve the dynamics and customize the character of the car.

As practice has shown, chip tuning of VAZ 2114 engines does not lead to tangible improvements.

Consider more serious improvements:

1. For owners of eight-valve engines, the most in a simple way improved dynamics will cylinder head installation from 16 valve engine. Modification of the 1.5 l block is also possible.
2. The easiest way to tune the VAZ 2114 engine is to install camshafts different from the drain. For example, OKB Dinamika 108 will gain at the top without a noticeable loss of the bottom.
3. By supplementing the shaft with a sliding timing gear and a suitable phase adjustment, you can get + 7 HP. from.
4. Installing an increased throttle valve (54 mm), a receiver and a spider 4.2.1 will improve cylinder blowing and give tangible changes during acceleration (the level is close to the Priore).
5. A modified cylinder head, lightweight valves and a modified intake manifold, paired with an increase in engine volume to 1.6 liters, will make it possible to achieve 110 hp. from. Tuning up to 120 horsepower will take place without loss of resource.

The principle of improving the power characteristics of sixteen-valve engines is similar to the process of revision of V8 1.5 l and V8 1.6 l. More evil camshafts, direct-flow exhaust, a receiver, an enlarged damper, a lightened prior piston group, in the case of a Kalina motor (124) and competent tuning will give a significant increase in dynamics.

Regardless of the number of valves per cylinder, the power of the VAZ 2114 engine can be significantly increased by installing a compressor or turbocharger. Engines modified in this way can easily reach 170-190 hp. from.

There are many different configurations and options for improving vehicle dynamics. You yourself can decide how to increase the power of the VAZ 2114 engine. Remember that the selection of mechanical modifications and software must match each other.

All cars of the Samara-2 family, rolled off the Volzhsky assembly line Automotive Factory, are completed with modern injection-type engines with electronic distribution of petrol injection.

Fuel injection on an injection engine

VAZ-2114 is no exception. For the fourteenth model, engineers developed a new power unit with nomenclature 2111. Despite the fact that in the last years of production, other engines were installed in VAZ 2114 - 21126, 21124, 21114 and 1183, it is the 2111 engine that is the most common. We will talk about it in this article.

You will learn about the technical characteristics, the nuances of the repair and operation of the VAZ 2114 engine, what are the features of its design and how the engine bulkhead of the fourteenth is done by hand.

The VAZ 2114 engine, in comparison with the power units of classic VAZs, has one key difference - the fuel injection system, the operation of which is controlled by an ECU ( the electronic unit management).

Due to the fact that electronics takes into account everything important nuances: the ratio of gasoline and oxygen in the fuel mixture, the required injection moment and the composition of the exhaust gases, the engine of the fourteenth in operation manifests itself in the best way - it is durable, powerful and economical.

The 2111 engine is a 4-cylinder, 8-valve device with four strokes. The arrangement of the cylinders is in-line. The motor itself is engine compartment placed perpendicular to the direction of movement of the vehicle.

The VAZ 2114 engine diagram is as follows:

1. Cooling mixture supply tube;
2. BC (cylinder block);
3. Thermostat;
4. A sensor that determines the temperature of the coolant mixture;
5. Outlet pipe;
6. BC valve;
7. BC cover;
8. Fuel mixture pressure sensor;
9. Oil container cover;
10. Throttle activation cable;
11. Throttle block;
12. Idling regulator;
13. Throttle position sensor;
14. Receiver;
15. Rear part of the housing of the gas distribution block;
16. Front of the case;
17. Fuel injectors;
18. Fuel rail plug;
19. Fuel rail;
20. Gasoline intake manifold;
21. Intake manifold support (right);
22. Pulley;
23. Oil filter;
24. Crankshaft position sensor;
25. Crankcase bottom;
26. Intake manifold;
27. Connecting rod;
28. Crankshaft;
29. Collector support (left);
30. Flywheel.

The engine we are considering has a cast cylinder block, the holes for the oil supply in which are machined, and the holes for the antifreeze are made during the casting process. Engine cylinders are also machined inside a monolithic structure.

In the lower part of the structure, there are supports for the main bearings, the covers on which are an indispensable part of the engine - they are adjusted in size at the stage of manufacturing the supports, and it is impossible to find two covers of the same size.

Inside the supports are inserts made of steel-aluminum alloy, and inside the third support there are half rings that prevent axial displacement of the crankshaft.

The pistons of the VAZ 2114 engine are aluminum, with cast steel rings, the connecting rod is steel. The cylinder block of the fourteenth is located on a metal pallet, on top of which a vibration-damping lining is laid.

Owners of the fourteenth are advised to check the integrity of this lining from time to time, since when it wears out, the sump, which is a hollow container for storing oil, can be damaged during driving over bumps due to the pressure of the cylinder block.

The crankshaft, located under the cylinder block, is equipped with a flywheel mount. The lightweight flywheel on the VAZ 2114 has a special mark, by means of which its correct position on the crankshaft flange is selected - it must be placed strictly perpendicular to the neck of the cylinder No. 4 connecting rod.

Consider the main specifications engine 2114:

• Torque - 166 Nm / 3000 rpm;
• Volume (l) - 1.5;
• Number of cylinders - 4 (two valves for each);
• Diameter of cylinders (mm) - 82;
• Fuel compression ratio - 9.8;
• Power (hp) - 78

It should be noted that the design features of the engine make it possible to increase its power up to 120 hp. without significant loss of service life.

• Gasoline consumption per 100 km (l) - 7.3;
• Engine weight (kg) - 127.

According to the manufacturer, the resource of the power unit is 150 thousand km, however, in practice, overhaul of the engine of the fourteenth is required, as a rule, in the region of 200-250 thousand km of run.

In 2010, 16-valve engines began to be installed on the VAZ 2114. This modification of the fourteenth was named "super-car", in honor of CJSC "Super-Auto", which was engaged in its production.

16 valve engine VAZ 2114

16v engine specifications:

• Torque - 131 Nm / 3700 rpm;
• Volume (l) - 1.596;
• Number of cylinders (mm) - 4 (diameter 82 mm, in-line arrangement);
• Fuel compression ratio - 10.3;
• Power (hp) - 89;
• Max. speed (km / h) - 190;
• Acceleration to 100 km / h (s) - 11.2;
• Consumption per 100 km (l) - 7.6.

Repair of the VAZ 2114 engine should begin with emptying the oil and coolant containers. Next, you need to dismantle all the attachments and clean the motor from oil and dust accumulated on it during operation. After that, you can proceed to the bulkhead.

1. We dismantle the fuel supply pipes;
2. We remove the hoses for air supply and exhaust;
3. We remove the crankcase breather and cooling system pipes. Remove the throttle pipe;
4. Next, you need to unscrew the receiver and the fuel rail, which will make it possible to remove the nozzles;
5. We dismantle the collector on the VAZ 2114, it is fixed on brackets, the nuts on which are unscrewed with a 13 key;
6. Disconnect and remove the wiring to the ignition module and unscrew the spark plugs. Remove the ignition sensor;
7. We remove the tension belt from the generator, after which we dismantle the entire structure. Together with the generator, we remove all elements - strips and brackets with which it was fixed;
8. We dismantle the generator pulley, having previously blocked the flywheel;
9. Remove the camshaft drive along with the pulley and tension belt;
10. We unscrew the pump, remove the thermostat and the exhaust manifold;
11. The next step is the oil pump at the VAZ: dismantle the filter and crankcase, then remove the pump itself;
12. Next, we dismantle the piston block. To do this, unscrew all the nuts on the connecting rod bolts and remove the block housing cover;
13. From the previously locked flywheel, we twist all the flange mounts and remove the disk;
14. On the main bearings, unscrew the covers and take out all the lower liners located in them;
15. Dismantle the crankshaft. This must be done extremely carefully in order to prevent any deformation of the structure;
16. Remove the stop half rings and the upper liners.

VAZ 2114 engines that have passed several hundred thousand kilometers have a fairly large number of worn parts. You will see this for yourself during the bulkhead process. All engine components that show serious signs of wear or damage must be replaced with new ones.
