The volume of 2.7 liters produces 128 hp. with a torque of 210 Nm. The second engine with which UAZ Patriot is sold today is a 2.2-liter diesel with 114 hp. at 270 Nm of torque. Diesel is also collected at ZMZ (Zavolzhsky Motor Plant). Today we'll talk in more detail about these power units for a domestic SUV.

Petrol engine Patriot, this is the ZMZ 409, which became the successor to the well-known 406 motor. Inline 4-cylinder 16-valve power unit with aluminum block and aluminum cylinder head. The engine has two overhead camshafts that move the valves by means of hydraulic lifters. That is, you do not need to manually adjust the valves on this motor. Injection injection allows the engine to comply with the Euro 4 environmental standard. There is a chain in the timing drive. It would seem that there could be more reliable, but it is the chain that is the weakest point of the motor. The constant complaints of the owners about the open circuit forced the manufacturer to abandon the use of Chinese hydraulic chain tensioners, replacing them with German ones. Further more detailed technical characteristics of this engine.

• Fuel consumption in the city - 15-17 liters
• Combined fuel consumption - 13-14 liters
• Fuel consumption on the highway - 11.5 liters

The fuel consumption of the gasoline Patriot is a separate topic, since in off-road conditions with all-wheel drive turned on, with the air conditioner running, the consumption can reach 25-30 liters per hundred. Therefore, it is not possible to accurately determine the real consumption, due to the huge number of concomitant factors affecting the consumption of Patriot gasoline.

Diesel engine UAZ Patriot ZMZ-51432, which is now installed on domestic SUVs, has recently been mastered. Prior to that, a 2.3-liter IVECO unit was installed under the Patriot's hood. The domestic motor produces approximately the same characteristics. Power 114 hp with a torque of 270 Nm. Inline 4-cylinder 16-valve Common Rail turbo diesel with "BOSCH" injection has an aluminum block and a block head. The timing drive is also a chain drive. Diesel is significantly more expensive than the gasoline version, therefore it is offered only in the most expensive trim levels. Diesel Patriots are not very popular in spite of significant fuel economy and increased torque. Further detailed characteristics of the turbodiesel power unit.

The main gift to all lovers of Russian SUVs this year will be presented by ZMZ in the summer, a new Patriot will appear on the UAZ conveyor. The more modern UAZ-3170 will receive a new gasoline engine, which will replace the 2.7-liter unit, which is very voracious and not very dynamic. The new ZMZ gasoline engine will have a smaller working volume (rumored to be 2-2.4 liters), while the engine power will increase, and fuel consumption will be significantly reduced!

The main unit of any machine is the engine. Pickups, sedans, convertibles, buses, tractors simply cannot perform their direct duties without an engine. That is why great attention is paid to the motor when choosing a car, its maintenance and operation. In addition, this is one of the most expensive units. Replacing or repairing it almost always costs a lot of money, requires a lot of effort and time.

For an SUV, the reliability and technical condition of the engine is even more important. After all, a breakdown of an engine in a forest, a field, far from roads and people can end up really sad.

A bit of history

The first UAZ Patriot left the assembly line in 2005. It was a truly new UAZ, incredibly modern in relation to past models. The manufacturer has positioned this car as a safe, reliable and powerful SUV. The design was good for 2005. And if you look not previous models, the design seemed perfect.

In October 2014, the new Patriot was introduced. It got a rear stabilizer bar, a touchscreen display, glued glass, a more attractive appearance, and the bumpers were now attached to the body. However, there were big security problems. Therefore, in October 2016, UAZ showed another update. "Patriot" received frontal airbags, even more attractive and modern appearance. The overall safety and soundproofing of the SUV has improved. Finally, the car got rid of the two fuel tanks that tormented all owners.

What engines are there for the UAZ "Patriot"?

Throughout the first generation, a permanent 2.7-liter gasoline engine with a capacity of 128 horsepower was installed. In 2008, engineers added a 2.3-liter diesel engine with 114 horsepower. It was the Iveco F1A engine. It was installed during the production of Fiat Ducato cars in Russia. This motor was later removed. Since 2012, the ZMZ-514 turbodiesel has been installed. Because of this, the working volume of the engine decreased by 65 cubes. Thus, the improved UAZ Patriot engine received an index of 2.2d. The same motor remained after the update in 2014. But the gasoline engine has undergone some changes. As a result, its official power was 135 liters. from. On the newest UAZ "Patriot", heavy fuel engines are no longer to be found. The diesel engine was abandoned. The gasoline engine was left unchanged.

Diesel engine

The turbodiesel "Iveco F1A" was, although expensive, but a really reliable engine. In addition, it allowed to reduce the Patriot's appetite to twelve liters per hundred kilometers of run in the city. A calm driver could get fuel and ten liters in the city. Not bad for a frame SUV. In addition, despite the lower power, when compared with a gasoline engine, it made the car much faster. The petrol version was lost after 80 km / h, while the turbodiesel easily accelerated to 120 km / h. This is due to the torque, which was equal to 270 N * m, against 218 "gasoline Newtons". The diesel also performed much better off-road. It helped to get rid of the turbo lag. Traction was always enough.

In 2012, the UAZ "Patriot" diesel engine from the Italian manufacturer was replaced. Replaced with the infamous ZMZ-514. It was developed back in the 90s. Had a lot of engineering errors that affected reliability. Cracks in the cylinder head, the valve disc getting into the cylinder, the high pressure pipeline breakage and many other problems are still dreamed of in nightmares by the owners of diesel "Patriots".

According to engineers, most of the problems have been resolved. Changed suppliers of low-quality components, finalized the motor together with Bosch. This is how the very reliable diesel engine UAZ "Patriot" turned out. Reviews confirm this. Since mid-2012, when the Common Rail system began to be installed, the motor did not cause any particular problems for the owners. Moreover, in terms of driving qualities and characteristics, the UAZ Patriot engine powered by the ZMZ diesel engine almost completely coincided with the turbodiesel from Fiat Ducato. Despite this, the manufacturer has phased out the diesel engine since October 2016. Perhaps there was a low demand, or maybe this engine was too expensive for the plant, but it is no longer possible to buy a new diesel "Patriot".

Petrol engine

The first generation of the Patriot received a 2.7-liter gasoline engine. Its power was 128 forces. After the 2014 update, the official power increased to 135 horsepower, and the maximum torque dropped by one N * m, from 218 to 17 N * m. However, when tested on a dyno, the factory cars of 2015 showed more than 140 forces. This engine went to UAZ from another 24 Volga, albeit with some changes. And in the "Volga" the declared engine power was 150 horses.

A car with this engine has always cost less in the showroom and on the used car market. The advantages include the relative reliability of the power plant. The engine on the UAZ "Patriot" has good maintainability, and spare parts for it cost almost nothing. This has always won over people who choose a Russian SUV, because repairing a diesel engine is many times more expensive. But you definitely won't save on gasoline. Less than 15 liters per hundred in the city is simply unrealistic for a gasoline "Patriot". If you stand in traffic jams, try to actively accelerate, then a flow rate of 20-22 liters per hundred kilometers is ensured. And if you consider that a car with this engine simply does not go (acceleration to 100 km / h is 19 seconds), then you have to turn this engine.

Gasoline engine problems

The childish appetite of the 2.7-liter UAZ "Patriot" engine is not its only problem. The chain break plagued many SUV owners. In 2017, the manufacturer changed the supplier.It remains to be seen whether this will solve the problem.

Conclusion

What is the ideal engine for the Patriot? Diesel from Iveco. 500,000 kilometers walk without any problems. Repairs are cheaper than the ZMZ diesel. Are you buying a new car? There is simply no choice. The gasoline engine is very reliable, you only need to follow the chain.

The UAZ Patriot SUV is a car for drivers who prefer to move not only on asphalt, but also on rough terrain. The engineers of the Ulyanovsk plant have created a real steel horse designed for off-road. Sitting in the salon, you can feel absolutely comfortable, but over time you realize that something is missing. This is something about not only changing the look of the car, but also upgrading the engine. If chip tuning is a passive form of improving technical performance, then replacing an engine is an essential way to modernize a car. It is on the replacement of the internal combustion engine of the ZMZ-409 brand installed on the SUV that will be discussed today. Let's consider what types of engines of domestic and foreign production can be installed on the UAZ Patriot.

What kind of foreign engine can you put on a domestically produced SUV to improve the technical performance of the Patriot? The first option is to install a motor from a Toyota Surf car. In addition, to install a new engine, you do not need to have engineering knowledge, for this you simply need to purchase a unit. There are some features for installing a Toyota Surf engine on a UAZ. Let's consider them briefly:

1. The mountings of the standard motor must be moved a few centimeters forward and the angle of inclination changed. The angle of inclination is needed in order to accommodate vibration-free pillows.
2. Before installing the engine, it is also necessary to remove the power steering bracket. It will rest against the timing, so problems may arise.
3. The radiator remains standard. It does its job well. It will be able to provide cooling of a Japanese-made engine completely.
4. The air filter is located on the left side of the engine compartment.
5. It is also recommended to replace the exhaust system, that is, to use the Japanese version, which is more reliable.

After replacement, you can find the following improvements:

• Fuel consumption will be reduced.
• Problems with the transfer case and gearbox disappear.
• Dynamics improves.

Whose else can you install the engine on the UAZ Patriot? In addition to the Toyota engine, a domestic engine from the GAZ-53, better known as the V8, can be installed on the car.

V8 engine

The well-known GAZ-53 truck with a V8 engine, which means the presence of eight cylinders, is still used today. The car has an excellent engine that can be installed on the UAZ Patriot. The V8 engine from the GAZ-53 has a power of 115 hp. and considerable torque. In addition, this unit perfectly replaces the standard SUV engine.

To fulfill the dream of installing a V8 engine in your car, you need to replace the exhaust system, transfer case and gearbox. After installing the V8 engine, the power of an SUV is felt, which is ready to overcome difficult off-road and obstacles, and to pass through swamps, reservoirs and snowdrifts. With the V8 engine from the GAZ-53, the SUV is not afraid of high-speed traffic on the highway. Below is a video showing the UAZ Patriot with an installed V8 engine from GAZon-53.

After watching the video, you understand what an 8-cylinder engine from a Soviet mid-engine is. With the new V8 engine, Patras is much louder, which it should be. Domestic-made engines are famous for their endurance and efficiency, so by installing such a V8 engine, you can forget about the standard engine forever, since you will no longer want to return it.

The GAZon engine is more powerful than the standard one from the Patriot. But its main advantage is reliability, which cannot be said about modern motors.

Motor from Nissan

If there is a desire and finances, then you can install a more powerful engine on the UAZ Patriot than the GAZ-53. This is the Nissan Kid 32 engine from the Galagrin company. The power of such a unit is approximately 150 hp, which is more than necessary. What should be noted is that this unit from the Nissan Kid 32 is diesel. 150 h.p. also suitable for an electronically controlled machine. With manual control, the power is reduced to 135 horsepower.

Of course, no one says that the Nissan Kid 32 engine is installed new, you can put it on a contract basis. The reason is that the new units must comply with the Euro-4 environmental standard.

After replacing the standard engine with the Nissan Kid 32, the UAZ Patriot SUV is characterized by the following parameters:

1. Increased power. Now the SUV can not only get out of any trouble, but also pull out its own kind.
2. The consumption increases, which is justified by the increase in power.

To install the Nissan Kid 32 engine on the Patriot, the latter will require a suspension lift.

Cummins

In conclusion, I would like to note the advantages of the Cummins engine, which are also excellent for a new generation SUV. First of all, it should be noted that Cummins is exclusively engaged in the production of diesel engines, famous for their durability, economy and safety.

Cummins engines are installed in Gazelle cars. Cummins is suitable for those types of vehicles that are designed for off-road and asphalt conditions. Therefore, if you often operate your car on mixed types of roads, then it is Cummins that will be the best solution.

Summing up, it should be noted that today we have examined superficially the types of engines, both domestic and imported, that can be installed on your SUV. In many cases, of course, improvements are required, but still, replacement is done at home. Which motor to install: imported or domestic - it's up to you, the main thing is that the chosen option fully meets your needs.

You can check your MSC and reduce it if needed!

Two humps are only good for a desert ship. But an SUV is not a camel, a double-humped torque curve for its engine is not the best option. That is why I shuddered when my good friend Volodya Sharandin invited me to drive the Patriot along the ice track.

We passed, we know! Drive when after the first burst the thrust drops to three thousand revolutions? Dubious pleasure. Even the next surge in the region of four thousand does not help. Yes, and high-speed exercises on the Ulyanovsk all-terrain vehicle seemed to me akin to off-roading on a passenger puzoterka.

But Volodya knows how to persuade and, frankly, never offered stupid ideas. Moreover, he had not been home for fifteen years, and during this time he became a cool automotive engineer, complementing his Russian education with American and European. Today his strong point is civilized tuning in its own center. In general, I was intrigued: UAZ in its performance should be extraordinary.

Gave traction

The door slammed and I was driving the Patriot. Everything is familiar, only the engine sounds strange. Not louder, but the tonality has changed, and for the better. I like this song better than the old one. How about on the go?

Here the moment is two hundred and seventy and the power is one hundred and eighty. Don't be shy, spin until you cut it off!

Sharandine urges, but you don't have to ask me for a long time. Gas to the floor! I didn’t drive such a Patriot - it accelerates very quickly! It even became a little scary: you have to get used to the brisk character, because the chassis and brakes are standard, but the agility is different. Vnatyag? And at the bottom, this Patriot is more convincing. Lucky exactly, without plugs. Especially after 1800 rpm.

A surprise awaits me on the track - a standard Patriot. Volodya envisioned this “piano in the bushes” so that I could change from car to car - for comparison. Well, go ahead!

First, a small motocross piece. You can't accelerate here: continuous hills with steep descents and ascents. Serial Patriot took all the slides - some in first gear, some in second. And in a car with a modified engine, you can go differently: after a couple of climbs, I stop switching - there is enough traction, I go through the entire obstacle course in second gear.

The highlight of the program is the autocross track. Turning corners and appendixes, ice interspersed with snow porridge. The serial Patriot, with its weight and overall height, handles well on slippery roads. Of course, we have to be active. I twist it at large angles - tea, the mechanism is not rack and pinion. In areas with loose snow, so as not to lose speed, I switch from third gear to second. I switch frequently, but in general - bearable. To be honest, after this "race" I changed my opinion about the Patriot for the better, but did not get much pleasure. Still, a serial UAZ is not for drifts and drifts, storming turns with a fan is not his element.

Now - 182-strong car. Truly, there is never too much power and moment! The chassis is the same, but the ride is more pleasant and, most importantly, safer. Almost the entire track is in third gear, switching only in a couple of places. Now I understand why Sharandin invited him exactly: this Patriot is already controlled by gas - and you enjoy the process. Instead of oiling the steering wheel, you can actively use the traction - the engine, one might say, pulls the Patriot out of the demolition.

Arrived in our shelf

At the base where Volodya is finalizing the cars, homework is already in store.

Look, we managed to smooth out the humps, not just raise the torque!

Sharandin puts out a printout of the external speed characteristics of the motor, taken on the MAHA roller stand. Indeed, an almost flat shelf of 260–270 Nm in the range of 1800–4800 rpm. And the power is much higher: 182 hp. at 5200 rpm. The serial engine produces 134 hp, and the maximum 217 Newton meters - the same humps at 2500 and 4000 rpm. The most curious thing is that such results were achieved without opening the engine and, accordingly, without installing new shafts, pistons, connecting rods. Only inlet and are changed.

Direct flow? Whom will you surprise! Everything is much more interesting than the primitive struggle against backpressure - here the intake and exhaust are coordinated.

Shelf alignment technology is as follows. First - 3D scanning of the engine compartment and the underside of the car. This allows you to evaluate the space in which new parts are to be placed. Then comes the calculation and design of iron.

The task is to boost the engine by improving the filling of the cylinders. To do this, work with air flows at the inlet and outlet and harmonize the wave processes in the engine.

Then an exhaust manifold is made with pipes of equal length. The "spider" of the 4-2-1 scheme fit into the UAZ (the 4-1 variant cannot be placed in the engine compartment). That is, the pipes are first merged in pairs, and then they go into a single pipe. Next are the modified resonator and muffler. Everything is stainless steel.

And also a non-standard intake. The low resistance filter is installed in a cold zone where the air density is higher. Behind it is a diffuser and an intake pipe. Their diameters, roundings, dimensions are the result of calculations and experiments. After all, the air flow does not like a sharp change in direction, sharp contractions and expansions.

After assembling the components on the car, the fine-tuning procedure begins on the MAHA roller stand. The wheels are scored and the electronics plot out power and torque curves. In the initial version, telescopic pipes are used - by changing their length, the developer adjusts the characteristics. Volodya, although he is a race car driver in the past, prefers to rely not on high revs, but for a moment - such motors are much more convenient in everyday use. The Patriot is a very special case: improvements should not affect his all-terrain qualities. To lose traction at low revs is to ditch.

If it is possible to get a weighty additive due to "inhalation-exhalation", that is, inlet and outlet, why does the plant not do this?

Features of mass production do not imply individual selection of engine characteristics and work on "gold" technologies. There the average setting rules the ball. "Eternal" stainless steel outlet, playing with telescopic collector pipes, rejection of a filter box in favor of a filter of low resistance - the lot of small tuning firms. And they kill several birds with one stone.

Moderate forcing does not affect. In this regard, working with a hitch is a much less risky business than disassembling the engine with the replacement of expensive parts. And, which is very pleasant, the price is not exorbitant. The modified intake-exhaust system costs about 50 thousand rubles - taking into account the installation and settings.
