In the northern regions, the problem of starting the engine in the cold is always relevant - frost thickens the oil, complicating cranking and worsens the volatility of the fuel, and reduces the current output of the battery. Even the difference in the thermal expansion of individual parts plays a role: the piston with a floating fit of the finger bites it in the cold, and the lower head of the steel connecting rod is compressed more than a cast-iron crankshaft.

Therefore, starting the engine, you have to warm it up so as not to risk breakdown when starting to move. Here the minus of already diesel engines is revealed: at idle they slowly heat up even in summer, while in winter it is impossible to warm up a diesel engine in morse. Running in the cold - there is a considerable risk of cranking the crankshaft liners, scuffing the camshaft beds.

The practice of preheating the engine is as old as the cars themselves - and now you can see how the engine is heated with a blowtorch. But this method is inconvenient and unsafe. So both home-made and factory engine preheater systems appeared a long time ago and continue to remain relevant.

Operating principle

The idea of \u200b\u200ban engine preheater is simple: since the engine is filled with antifreeze, then by heating the antifreeze from an external source, it will be possible to evenly heat the engine itself. The working clearances between the parts will return to normal, the oil will warm up (it will heat up in the sump from the heat of the crankcase and on many machines, after starting, it will start to pass through the oil-and-oil heat exchanger) and the intake manifold. For diesels and engines with distributed injection, this is less important, for a carburetor motor, heating the manifold and the carburetor itself in the area of \u200b\u200bthe idle system jets is necessary. The motor will give part of the heat to the gearbox, which is also important. Once in the car, you can immediately defrost the glass.

Preheaters are divided into two categories

1. Electrical.
2. Autonomous.

The simplest prestarting electric heaters are heating elements in metal pipes, cut into the lower radiator pipe. Such structures are homemade due to their simplicity; in the northern regions of Russia you can see cars with a 220V plug sticking out from under the hood. In Northern Europe, you can even find parking lots where each parking space has a post with an outlet.

The minus of this is also clear - heating is slow due to the lack of forced movement of fluid in the circuit. It is avoided by introducing an additional electric pump into the cooling circuit, but the need to connect the preheater to an external power source each time remains. But electric heaters do not lose popularity, there are interesting models that warm up the engine and at the same time recharge the battery.

The liquid (autonomous) heater is connected to the electrical system, fuel line and the cooling system.

But how to warm up the engine when there is no outlet nearby? There is only one option - to burn your own fuel. This is how autonomous pre-heaters are arranged: these are small stoves that burn fuel taken from the tank and heat the built-in heat exchanger. It is easy to automate such a pre-heater - connect a timer to it, an alarm control output. Thanks to this, on commercial vehicles, such models, for which you can even set a weekly heating schedule, are installed from the factory, and the manufacturer's name autonomous heaters Webasto repeated the fate of Xerox, becoming colloquially synonymous with pre-heating systems.

Of course, autonomous heaters have their disadvantages:

1. First, they need fuel - with an almost empty tank, you will be left with a cold car.
2. In the same way, a battery charge is needed - with old battery the engine will warm up, but the starter will no longer turn it.

Therefore, many heating systems integrated with on-board electronics are automatically blocked when the fuel level or the battery charge drops below a critical level.

The fantasy is not limited to this, but its other fruits are considered rather curiosities. For example, heat accumulators have been invented - these are thermoses in which a certain volume of coolant is stored. While the motor is running, the heat accumulator is included in the common circuit and is heated to working temperature, when the engine is turned off, it turns off, retaining heat in itself. Starting a cold engine, the driver again receives a dose of antifreeze that has retained heat. It is difficult to take such developments seriously because of the short "shelf life" of the heat supply and because of the size. But they manage to be sold - these are the Canadian Centaur systems and the Russian "AutoTerm".

If we recall the unambiguously useless devices, then these are oil heaters inserted through the dipstick. Not to mention the inefficiency of heating the oil in the pan, and the power of such "heaters" is so scanty that they cannot heat the oil, uselessly draining the battery.

Installation

Installation diagram Binar-5

The simplest electric heaters are installed simply - we drain the antifreeze, cut out the section of the lower radiator pipe to the desired length, insert the heater into the cut pipe, tighten the clamps and re-fill the antifreeze. It remains to stretch the wires so that the car is easy to "plug into the socket".

Why does the electric heater bump into the bottom pipe? This speeds up heating due to thermal convection - heating systems also work without forced circulation. When inserting into the upper pipe, antifreeze is heated in the radiator, and not in the motor - a closed thermostat will not allow liquid to flow into the block due to convection.

If you have not a cheap Russian heating element, but a more advanced device, then it crashes into the pipe that goes to the stove. Such devices are a monoblock that combines a prestarting heater with a low-power pump, so they cannot be connected to the main cooling line, which has a large flow area. But warming up the engine with them faster, and at the same time, the salon stove heats up at the same time.

For a number of motors, electric heaters are manufactured with the expectation of installing instead of technological motor plugs - to install them, you will need locksmith skills, since you will first have to remove the necessary plug from the motor, and then install the heater in the hole of the block. It is better to entrust this to professionals, as well as the installation of an autonomous heater - this will require intervention in the fuel system of the engine, and the proper placement of the exhaust of the heater.

The best models of electric pre-heaters

Defa

The Norwegian company is the leading manufacturer of this type of heater. It produces electric heaters, which both cut into the unit and are installed in the cooling circuit. The main advantage of Defa systems is modularity: the heater is complemented by charger for the battery, autonomous fan for the passenger compartment, on timer. If desired, choose a model of a heater with a thermostat - such a heater is left constantly on, without risking overheating the motor and saving energy, since when the set temperature is reached, the heater will automatically turn off.

Calix

Another Scandinavian firm. In her lineup universal heaters cut into the nozzles, they are simple, reliable and effective. Modular design is also used: the buyer can configure the desired system himself, by purchasing in addition to a suitable heater additional devices management, battery charging. Owners diesel cars will appreciate the presence of easy-to-install electric tank heaters in the Calix model range.

Severs

And these are the products of ZAO Leader. With all the advantages of European heaters, the price remains a disadvantage, so the proposals of the Russian manufacturer will not be superfluous.

The model range includes simple convection heaters and "Severs +" models with forced circulation. The heater is supplemented with a timer and a battery charger.

Popular autonomous preheaters

The German concern with a century of history is known primarily for autonomous heaters. OEM models are produced, installed on conveyors by the car factories themselves, and kits for self-assembly.

Each such set is created for a specific car and therefore stands up with a minimum of possible modifications. For control, its own blocks are used, which are interfaced with the heater with a proprietary digital bus. It is used in conjunction with modern alarms - for example, StarLine systems were able to control Webasto even in the last generation. Thus, the start of the heater is carried out by timer and by command from the alarm key fob and mobile phone.

Eberspacher

The second German "titanium", the brand of which did not become a household name, except because of the difficulty of pronunciation for the Russian language. Branded Hydronic heaters are universal units that are equipped with their own installation kit for a specific car model. Separately for cabins are produced air heaters Airtronic - they are relevant for commercial vehicleswhere the driver can spend the night in the cab in winter, while there is no point in spending fuel on constant heating of the engine all night.

Teplostar

The Samara manufacturer will be of interest to many: prices for Webasto or Eberspacher products were considerable even before the crisis, but now they have doubled. Teplostar's model range includes models of pre-heaters designed for different engine sizes, different fuels and voltage. An interesting feature of the company is that the heaters are equipped with GSM modules: you can turn on the heater from your own phone if you want.

An engine preheater is a device that allows you to warm up a car engine without starting it. It will be especially useful for those drivers who live in places with the coldest winters. Thus, God himself ordered Russian drivers to acquire such a system. The dimensions and power of the engine heating device depend on the application.

• vehicle interior;
• windshield;
• wipers.

The device includes:

1. The boiler, which houses the combustion chamber and radiator.
2. The piping system through which the fuel flows.
3. A pumping device responsible for pumping fuel and coolant.
4. Thermal relay used to control the fan.
5. Control unit.
6. Launch system.

Types of preheaters, principle of operation

If a car enthusiast uses this device, he will greatly facilitate starting the engine of his car at low temperatures. A car engine heater warms up the engine by raising the temperature of the coolant, oil, and glow plugs.

Electric engine pre-heater

It is a device inserted into the cylinder block. It operates from an external power supply and requires a voltage of 220V. The main component of such a device is a special electric spiral. When it is installed, the plug is removed from the cylinder block, which prevents the formation of ice. A spiral is mounted in its place.

Engine pre-heater operation happens as follows.

Due to the strong voltage, the electric coil heats up. The liquid circulates thanks to natural convection. This type of circulation is less efficient than artificial and more time-consuming.

For work electric heater 220V motor will need a permanent connection to the network. Plus it wastes a lot of electricity. A specially provided timer helps a little to save electricity, which monitors the temperature of the liquid and, when the desired degree is reached, automatically adjusts the operation of the device.

When using the electric engine heater, the battery can also be charged automatically. This feature will be very useful for drivers in the cold season.

Autonomous pre-heater

Systems that provide autonomous engine heating are, in turn, divided into two types.

Autonomous liquid preheaters able to heat not only the engine, but also the interior of the car. They are called liquid due to the fact that they use fuel from the tank of the car for work. In order for such a device to correctly perform all its functions, it must be installed in the engine compartment and connected to the system liquid cooling... Heating of the passenger compartment is carried out due to the access of warm air through the internal air duct.

The advantages of an autonomous engine heater for passenger cars include its economy. He does not spend a large number of electricity and fuel. During operation, it does not cause inconvenience to the driver and passengers with a loud noise.

You can activate the device using a timer, remote control or even a mobile phone. The signal activates the electronic unit, which, with the help of another signal, drives the executive motor. This motor, through rotation, makes it move fuel pump and a fan. The pump pumps fuel into the burner, where a fuel-air mixture is created, then ignition occurs with a candle. Then the heat generated by the combustion of the fuel is transferred to the coolant. The liquid circulates thanks to the pump and gradually transfers heat energy to the machine body. When the coolant has reached the desired temperature, a fan is turned on, which drives heat into the passenger compartment.

Air pre-starting engines have no effect on the car engine. Instead, they heat up the air in the passenger compartment faster. As a rule, such devices are not installed on cars, but are used on passenger buses... They do not consume a lot of electricity and do not make noise. However, in size they are much larger than their liquid counterparts and much more productive. True, fuel consumption is slightly higher in them.

Benefits of using preheaters

Car enthusiasts who have been driving a car for several years say that such a device in the conditions of the Russian winter is simply necessary for any car. Such devices increase the comfort of driving and reduce driver fatigue. They also extend the life of any engine and provide more economical operation.

It happens like this:

1. The heater reduces the number of cold starts of the motor. Each of these launches is accompanied by increased consumption fuel and, accordingly, increases the cost of its purchase. The heating device, thus, can save the driver about three hundred milliliters of fuel for each engine start. Fuel consumption depends on the temperature outside the vehicle. Thus, an engine pre-heater can save a motorist about one hundred and thirty liters of gasoline over the winter.

2. Heavy engine starts lead to premature engine wear.... This happens due to the fact that when the engine is started without heating, the viscosity of the engine oil is much higher than usual, and accordingly it loses some of its lubricating properties. Thus, wear is significantly increased, especially in the crank and piston mechanisms. Increased wear will inevitably lead to a reduction in engine life and quick breakdowns and malfunctions.

If it is cold enough in the car, the driver's body begins to give off much more heat, which leads to accelerated fatigue. As a result, drowsiness and distraction appear. The likelihood of catching both a harmless cold and a serious cervical or lumbar osteochondrosis also increases.

What is the best engine preheater to choose

For passenger car the best suited, of course, is an autonomous liquid engine heater. It is versatile, as it heats up both the interior and the engine at the same time. It is economical enough and can be launched remotely. Such a device is quite functional and can be installed on all types of cars.

Popular models:

1. Webasto Thermo TOP E is a classic liquid heater. It is very compact and can be used even in the smallest cars. Even during startup, it consumes little electricity, therefore it is considered one of the most economical. It can take a maximum of 15 minutes to prepare the motor for safe starting. In the summer, this model can even ventilate the cabin and replace the air conditioner. The only drawback is its price. Not every car enthusiast can afford such a device. But for wealthy drivers who value efficiency and economy, it is ideal.

2. Teplostar 04TS is a domestic device. It heats up the coolant and can be activated by the remote control from a distance of over 100 meters. However, if something happened to the heating device, the driver will only know about it when he gets into the car. However, it has another useful trait. The control unit of this model checks each system for operability before starting. If problems are found, the information is displayed on a specially equipped display. This model is usually chosen by those who need increased reliability and at the same time a low price.

3. Severs 103.3741 - another Russian engine heater. However, it is not self-contained and must be connected to the mains to operate. It is equipped with a special regulator that will not allow the engine to overheat. The engine is heated within an hour. The main advantage of the Severs engine preheater (220V) is increased protection against moisture and electric shock. This model is suitable for those drivers who put their car in the garage every evening.

With the onset of cold weather (usually "sudden" for any of us), each car owner thinks about whether his car will start or not. And even if the battery coped with the difficult task and the "cold start" was successfully carried out, with this method of operation, a number of negative consequences arise:

• engine parts wear out faster;
• the load on the battery increases: as a result, the service life is significantly reduced;
• the engine has been running for a long time idle (and, this is not the most "useful" mode of operation for him).

The preheating of the engine will not only prolong the "life" of the engine without repair, but also significantly increase the comfort of using the car in winter time.

The principle of operation and types of engine preheaters

All systems, regardless of design, installed in cars to facilitate starting the engine in the cold season, do not heat the engine itself, but increase the temperature of the surrounding coolant (they are called PZhD for short). Therefore, the antifreeze, which saves the engine from overheating while driving, warmed up with a pre-starting device, heats up the engine elements, which contributes to its easy start (even at very low temperatures).

According to the principle of operation, all engine pre-heaters (both gasoline and diesel) are divided into two main groups:

• autonomous;
• electrical.

The former use vehicle fuel as a source of energy. To operate the latter, you need to connect to a 220 volt power grid.

Autonomous pre-heaters

This type of engine pre-heaters is the most functional, since it does not depend on the connection to external energy sources (therefore, they are called autonomous). However, their cost is higher than electric ones. It is rather difficult to install such an engine heating with your own hands, without having the necessary technical skills and sufficient experience. Besides self-installation such high tech devices will void the vehicle warranty.

On a note! If the heater is installed in an authorized center, then all warranty obligations remain.

And despite the rather high cost, such devices are very popular. By analogy with autonomous heating systems for buildings, such devices are sometimes called boilers. Until recently, the most renowned manufacturers these products were German "Webasto" and "Eberspacher (Hydronic)". But now they are worthy competition Russian firms: "Binar" and "Teplostar"; and also the Chinese "Belief".

Autonomous heating consists of:

• fuel pump;
• glow plug or glow plug (tungsten or cobalt);
• evaporative burner;
• combustion chambers;
• heat exchanger;
• blower motor;
• coolant inlet and outlet pipes;
• control unit.

The boiler is installed in engine compartment and are built into the fuel and cooling systems of the vehicle. The diagram below helps to understand how an autonomous heater works.

When the device is turned on (with a button, a signal from a timer, a remote control unit or a GSM module), the air-fuel mixture enters the combustion chamber and is ignited by a glow plug (or a glow plug). When the mixture burns, the heat exchanger heats up, which leads to heating of the coolant. The pump pumps the antifreeze through the engine and radiator of the standard interior heating system. When the temperature of the liquid reaches about 60 ° C, the automation unit turns on the interior fan.

The heater "Webasto Thermo Top Evo Start" (5 kW), designed for installation on cars with an engine capacity of up to 5 liters, with a programmable weekly timer and installation parts costs about 25,000 rubles. The remote control unit (range of about 1 km) and the GSM unit (for the possibility of control from a mobile phone) must be purchased separately. Installation by a certified dealer will cost no more than 8000 ÷ 10000 rubles.

Passive electric heaters

In Canada and all Scandinavian countries, almost all parking spaces are equipped with sockets where such heaters can be connected.

In our country, only a few paid parking lots offer such a service. But, if you live in a private house or keep your car in the garage, then, undoubtedly, this device will greatly facilitate your life in cold weather.

Technically the easiest and most cost-effective way to preheat a diesel or gasoline engine before starting in winter - installing an electric heater in place of one of the engine block plugs. Technologically, it is a conventional boiler of a certain size and power. The circulation of the liquid is carried out by gravity (the heated one goes up, and the cold one goes down). The choice of product depends on the specific engine model. Devices are widely represented on the market, practically for all car brands from various manufacturers.

For example, electric preheating of the engine from "DEFA" for the VAZ "ten" with a power of 550 W with additional spacers (for better fixation with inside block of cylinders) and a sealing O-ring costs 1,700 ÷ 1,800 rubles. And for " Subaru forester»A similar device (with a threaded mount) with a power of 600 W from the same manufacturer will cost 2600 ÷ 2800 rubles.

Depending on the type of plugs, manufacturers produce such devices both for threaded installation and for pressing. The model is chosen depending on the type of the engine itself.

Having even minimal technical skills, it is quite simple to install such a device for heating an engine from 220 V with your own hands (with a cable and a socket for connection):

• partially drain the coolant (usually 2 ÷ 2.5 liters are enough);
• dismantle the plug on the cylinder block (located closest to the central part of the engine to ensure better heating);
• insert a heating element instead;
• we connect the electric cable;

• the outlet for connecting the mains or take it out through the radiator grill (for those who are not very worried appearance car), or we fix it in a convenient place on front bumper (or under it).

To make it convenient to use such a device, you can additionally set an on / off timer.

Electric heaters with forced circulation of coolant

Electric heaters with a pump (to circulate the heated fluid through the engine and the radiator of the cabin heater) allow the entire engine to warm up evenly. Although such devices are more expensive than passive electrical systems, the efficiency of their work is much higher. A thermostat built into the housing automatically turns off heating when the liquid temperature reaches 80 ° C.

The installation of such a device is quite simple:

• we drain the coolant;
• we fix the device case;
• we carry out a tie-in into the standard cooling system (between the exit from the cylinder block and the inlet pipe of the cabin radiator);
• fill in coolant.

Russian engine heater from 220 V "Sputnik NEXT" (power from 1.5 to 3 kW, which is chosen depending on climatic conditions operation and engine size) with a pump and automatic power off costs from 2,200 to 3,200 rubles.

Having supplemented such a relay device with a temperature sensor to turn on the stove fan, we can count on not only an easy engine start, but also the car interior warmed up to a comfortable temperature.

Flexible thermoplates

The above devices, built into the cooling system, do not provide oil heating in engines. This is their significant disadvantage. In severe frosts, even with a well-heated engine, turning the thickened oil is quite problematic. Flexible heating plates for preheating the engine allow you to easily make homemade device, rather quickly (in just 20-30 minutes) increasing the oil temperature. Technologically, they are a heating element pressed between two layers of silicone. An adhesive composition (3M) is applied to one side of the plate, and a porous material with good thermal insulation on the other. The power of one heating element is from 60 to 400 W. Such devices are produced for connection to the on-board network of a car with a voltage of 12 or 24 V, or to a household power supply of 220 V. The cost of these products from "Hotstart" or "Keenovo", depending on the size and power, is 2000 ÷ 8000 rubles per piece.

With the help of such devices, you can easily carry out heating of the engine sump or automatic box gear. One plate measuring 127 x 152 mm and 100 W is sufficient for a car with an engine up to 3 liters.

The installation of such products is quite simple:

• we clean the installation site from dirt and paint;
• then delete protective film and do not forget to glue the plate;
• apply a layer of sealant around the edges;
• we fix the electrical wires and drag them to the connection point.

By installing such plates (with a built-in temperature sensor) on the car's tank and fuel filter, you can create a heating device for the fuel system diesel engine.

The main advantages of such devices are:

• Low power consumption.
• The ability to use for heating a variety of components and mechanisms of the car.
• Easy to install (original vehicle systems remain unaffected).
• Autonomy (when using plates with 12 V power supply).

In custody

Which heater is the best to install on the car depends on your personal preferences, financial capabilities and parking space. By installing a heating system from a proven and well-proven manufacturer, you will not only save time, but also be sure that your car will start even in severe frosts.

An engine preheater will allow the owner of a car equipped with such a device to save a lot of time, nerves and energy with the arrival of cold weather. If you are faced with the task of choosing and installing an engine preheater for your car, we are ready to help you understand this issue.

An engine heater is a necessary attribute of a car that is operated in a harsh winter. In this article, we will consider the types of preheaters, their strong and weak sides, as well as give recommendations for installation, connection and operation.

You can watch a video instruction for installing a 220V pump pre-heater for an engine at the bottom of this page.

Of course, in our country there are enough craftsmen who are able to make a pre-heater with their own hands. But we strongly recommend not to engage in "amateur performance", but to give preference to high-quality factory products from manufacturers who have positive reviews motorists.

First, let's define what an engine preheater is. This is a special device that heats up the liquid in the car's cooling system (antifreeze) and makes it easier to start the engine at low temperatures.

The need for pre-heating disappears if the car constantly spends the night in a warm garage, as well as if the winter in the region is mild and the temperature rarely drops below -5 ° C.

Prestarting heaters fundamentally differ in design options and power sources, and are divided into two categories:

1. Electric engine preheaters are devices powered by an external power source. They are simple, so they have a low cost, and they are usually connected to a regular household outlet with a voltage of 220V.
2. Autonomous engine preheaters have a more complex design, and their price is noticeably higher than electric ones. They feed either from fuel system car, or have their own fuel tank.

Electric engine pre-heaters

The electric engine pre-heater is quite simple. Its design is a tungsten coil placed in a cylinder block. The heater is connected to an ordinary 220V socket, as a result of which the coil heats up and heats up the coolant.

Depending on the complexity and price, the electric pre-heater can be equipped with additional options:

• device for recharging the battery;
• fan;
• timer-thermostat;
• remote control.

The price of a 220V electric engine heater largely depends on the presence or absence of certain functions.

The disadvantages of electric engine heaters include high power consumption. Do not be surprised if, in just one night, the heater winds up an additional 10 kWh on the meter.

As for manufacturers, the most demanded in our country is the products of a Norwegian company. Defa.

Autonomous engine pre-heaters

An autonomous engine preheater is much more convenient than an electric one, since it does not tie the driver to a 220V outlet. Its principle of operation is based on the idea of \u200b\u200bnatural circulation of liquid (thermosyphon).

This means that the antifreeze warmed up in it rises (according to the law of physics about a decrease in the density of the heated substance), leaves the heater and enters the engine cooling system. There it cools down and enters the heater again. This is how a closed cycle is formed.

For the first time such mechanisms appeared in Scandinavia and some other northern countries. Gradually, they got to Russia. The main task of this technique is to maintain a constant temperature of the antifreeze at about 20 ° C.

Installation of an autonomous heater is carried out in one of 2 ways:

1. Connecting to the car power supply system;
2. Connection to the cooling system.

The engine type (petrol or diesel) does not play any role.

The principle of operation of an autonomous engine heater is quite simple:

• an air-fuel mixture is supplied to a small combustion chamber, which is subsequently ignited by a candle;
• the hollow walls of the combustion chamber are a heat exchanger (antifreeze circulates through them);
• as a result of fuel combustion, the antifreeze in the heat exchanger is heated to the required temperature;
• after heating, the pump supplies warm antifreeze to the small circuit of the engine cooling system.

The advantage of an autonomous engine heater is that, in addition to making it easier to start the engine, it provides almost instantaneous heating of the car interior, as well as defrosting of the windows. Installation of such an installation is possible in almost any convenient place under the hood.

The most popular manufacturers of autonomous heaters are companies Webasto and Eberspacher... They manufacture heaters for both diesel engines and gasoline engines.

In addition to standard functions, the list of available options for stand-alone models includes:

• timer-thermostat;
• remote control;
• control connection to a mobile phone.

DIY engine preheater

Can I make an engine preheater with my own hands? The video below shows just one of these homemade products.

It is not surprising that many do not want to spend money on installing an electric heating of the engine and intend to do it themselves. Russia has never complained about the lack of self-taught inventors, so there are many examples of such crafts.

Homemade heaters are made from a variety of materials. Most often, at home, they try to warm up the engine with devices:

• based on a blowtorch;
• from a tungsten spiral;
• from wire, and other improvised means.

All homemade engine heaters have two big disadvantage - this is a fire hazard (cases when cars and garages caught fire because of such devices are not isolated) and their low efficiency. So it is better not to save on the purchase of a high-quality pre-heater.

You can install the engine preheater with your own hands, since this process does not require any special knowledge and skills. Of course, a visit to a car service is always preferable, because there the whole range of work will be performed by professionals who will save time, as well as give a guarantee for work.

If you do not want to take money to the station or there is no way to stay without a car for a while, you can install the engine heater yourself (usually the installation instructions are included).

Video instruction for installing an electric 220V heater with your own hands, see below. The installation procedure for the heater is as follows:

1. Draining antifreeze (it must be drained to 2 liters);
2. Disconnecting the stove pipes from the engine cooling system;
3. Installation of the heater and its connection to the system;
4. Assembly (you need to tighten the unscrewed nuts);
5. Pouring antifreeze.

The whole process will take no more than 2-3 hours.

The advantages of installing an engine preheater are obvious:

• noticeable extension of the motor's resource;
• saving fuel on engine warming up;
• saving time;
• environmental protection.

By the way, if you have not yet installed an engine heater, you can read simple tipshow to start a car in frost.

Video instructions for installing a 220V engine heater from "Longfei"

The engine preheater is a special device that allows you to warm up power unit vehicle without running it. After all, very often occur in winter. Almost every motorist had a situation when he came to the parking lot for his car, but he would not start. The reason for this is low temperature environment. In such a situation, such a heater will come to your aid.

Its functions:

• preheating the power unit;
• facilitating the procedure for starting the engine in the cold season;
• heating the air space c.

This device keeps the engine at a constant temperature even when the machine is not running. Some modifications have a built-in heating function for the vehicle interior.

Having such a device in your car, you can start your car without any problems in the winter season. And also, you will not be afraid of the cold in the car, because you will quickly heat the air to the state you need.

Types of devices and their characteristics

There are currently four types of heaters. Let's consider them in more detail:

• Liquid heater... Now, this device is the best one on the market. With the help of it, you not only start your power unit without any problems, but also heat the interior of your vehicle. This heater is installed underneath and connected to the hot water heating circuit. The liquid device has the ability to connect a timer that will start working at a specified time. It has the ability to start via a radio signal or via a remote control. This device works almost silently and is very economical.
• Autonomous air heater... It is designed to heat huge volumes. Therefore, it is very often used in vans and buses. This device works quietly, heats the air quickly, and also consumes a small amount of fuel.
• Electric heater engine (on-line heater). The principle of operation of this mechanism is that an appropriate heating device is installed in the cylinder block, operating from a 220 V electrical network.This device is suitable for those motorists who store their vehicles in garages, that is, where there is an electrical outlet. After all, it only works on electricity. If you leave your car in a parking lot, then an electric heater simply won't work for you. Look for alternatives.
• Heat accumulator... This device works on the principle of accumulating hot cooling inside itself. He is able to keep the set temperature for an average of two days. During engine start hot antifreeze passes through the cooling circle several times, thus heating the power unit in a short period of time.

Almost all prestarting mechanisms have similar operating principles. Such devices have combustion chambers made of stainless steel, where fuel enters with the help of a nozzle, and air through a fan. This is where the mixture is ignited. It is done from a glow plug or from a candle. Antifreeze heating occurs due to an increase in temperature during the combustion of the air-fuel mixture. A pump installed in the cooling system pumps liquid, and this heats the entire system. Then, the stove fan is connected, with the help of which the interior of the vehicle is heated.
