UAZ Patriot engine, which was installed on last year’s model, remains on the restyled UAZ Patriot 2015. There have been no major changes; buyers are offered a choice of petrol and diesel engine options. Both engines are ZMZ brand. The ZMZ-51432.10 CRS diesel engine with a Common Rail fuel supply system and turbine complies with Euro 4. The new gasoline ZMZ-409 also complies with Euro-4 and is ready to digest AI-92 fuel. Today we will talk in detail about the characteristics of both engines.

So, benzie new engine UAZ Patriot ZMZ-409, this is a 4-cylinder, 16-valve, in-line, with an integrated microprocessor fuel injection control system. Injection injection fuel is carried into the intake pipe. An ignition system with coils that supply current to spark plugs screwed vertically into the center of the combustion chambers. IN cylinder head cover There are even special wells for this. Microprocessor system With electronic unit engine control, automatically controls the ignition timing.

Cylinder block power unit cast from cast iron alloy, aluminum cylinder head, with two camshafts and hydraulic valve compensators. Timing chain drive. Wherein, chain device gas distribution mechanism UAZ engine Patriot is quite complex because it consists of two circuits connected through intermediate shaft. Plus there are two hydraulic chain tensioners with sprockets. This whole structure is weak point of the entire engine, since insufficient tension and failure of the hydraulic tensioner lead to increased operating noise of the UAZ Patriot engine. In addition, hydraulic compensators often fail, which leads to knocking valve mechanism.

Naturally, the manufacturer does not provide objective data on the fuel consumption of the gasoline Patriot in urban conditions. The reason is clear, quite high consumption fuel may deter buyers. If you want to save on fuel, then buy a UAZ Patriot with a diesel engine, which we will talk about later.

Diesel UAZ Patriot assembled at the same Zavolzhsky Motor Plant. In-line 4-cylinder, 16-valve power unit with two camshafts. Timing chain drive, with hydraulic tensioners. The valve mechanism has hydraulic compensators. The cylinder block is cast iron, the cylinder head is aluminum, there is a turbocharger. The ZMZ-51432.10 CRS diesel engine with a Common Rail fuel supply system has an electronically controlled “BOSCH” fuel supply system with maximum pressure injection 1450 bar. To drive the injection pump (high pressure fuel pump), water pump and generator, a poly V-belt with an automatic tensioning mechanism is used.

UAZ Patriot diesel engine, with direct fuel injection, turbocharging and cooling charge air complies with the environmental class Euro-4. This engine It has good torque, which is indispensable for off-road use, plus quite moderate fuel consumption. Below detailed characteristics diesel engine Patriot.

The Patriot diesel unit has a problem with the 5-speed manual transmission gears, which does not allow you to use all the advantages of the engine. When driving on the highway, the diesel engine simply lacks 6th gear. Although it is ideal for off-road use. By the way, the box for gasoline engine It has gear ratio main couple 4.11, diesel 4.625. When purchasing, it is recommended to install preheater, otherwise in winter there will be problems with starting this engine.

UAZ Patriot new engine for SUV 2017 model year now answers environmental standards EURO-5. In essence, this is a well-known 2.7 liter 4-cylinder 16 valve unit. Another modification of the ZMZ 409. This time under the hood of the Patriot they put new version ZMZ-40906. The engine has become not only more environmentally friendly, but also more powerful. Zavolzhsky engineers motor plant managed to increase power to 135 hp, and increase torque to 217 Nm.

By the way, the UAZ diesel engine was temporarily abandoned in Ulyanovsk. Sales of UAZ Patriot with such an engine did not exceed a few percent. Despite the fuel gluttony, the majority of buyers choose the gasoline version.

Design of the new Patriot engine

The basis of the power unit for the PATRIOT 2017 model year cast iron block, inline 4-cylinder engine with overhead camshafts has hydraulic compensators. The block head itself is naturally made of aluminum alloy with 16 valves.

Gasoline injection With electronically controlled Even after optimizing all processes, you will not be pleased with the efficiency. Which is not surprising given the rather impressively large volume of combustion chambers. True, there is a plus in this; you can safely use AI-92 gasoline. This engine tolerates conversion to gas fuel quite well. If consider real consumption fuel, which in the city (and even more so off-road) can easily exceed 20 liters, then installing LPG will pay for itself quite quickly.

Timing drive Patriot 2.7 liters

The gas distribution mechanism drive on the new Patriot engine is still chain driven. It would seem that the chain is quite reliable and durable. However, in the design of this motor, the chain is a complex set of several circuits intermediate shaft, dampers and tensioners. The mechanism is quite complex and confusing.

The manufacturer is constantly working on the reliability of this unit. After all, the first generations of engines had a number of shortcomings related specifically to the timing. The hydraulic tensioners alone (which constantly fail) are worth it. The chain mechanism itself is covered with an aluminum cover. The condition of the unit can be assessed either visually or by a characteristic grunting sound.

Today, ZMZ is working on a new generation of gasoline engines for the UAZ Patriot; they will be 2.3-liter gasoline turbo engines with a capacity of 150 to 170 Horse power(at a torque of 300 to 350 Nm). In addition to reducing volume and introducing turbocharging, new Patriot engines will receive a variable valve timing system. True, no one names the exact timing of the appearance of new engines.

With the advent of new SUVs from UAZ the lineup domestic cars replenished with new copies (moreover, the UAZ Patriot engine is produced both in Russia and abroad). Only three types of engines are installed on SUVs (one of them is gasoline, the other two are diesel).

All engines installed on the UAZ Patriot comply with environmental standards Euro-2, Euro-3 and Euro-4. One of the engines is foreign-made (it was borrowed from Fiat car Ducato, manufacturer - Iveco).

These engines are installed on the entire UAZ Patriot model range. In other words, when choosing a pickup truck, you can find three identical cars with various engines. Which one to choose is a personal matter. But before purchasing, you should study the features of each engine and find out what they are individually.

Gasoline engine UAZ Patriot

The power unit is produced by the Zavolzhsky Plant (ZMZ), located in Nizhny Novgorod. It has injection system injection and full compliance with Euro-2 environmental standards. ZMZ supplies these engines not only to UAZ, but also to Pavlovsk and Gorky automobile factories. From this we can conclude that in case of repair, spare parts are very easy to find (and many people, when buying a car, look at this almost first of all).

With an engine capacity of 2.7 liters, fuel consumption in city mode: 14.5 liters, and when driving on the highway - four liters less. UAZ Patriot engine power at 4400 rpm is 128 horsepower. The engine has two camshafts (for intake and exhaust valves).

The main task of the car is to drive confidently in difficult places. The load on the UAZ engine is much greater than that of any passenger car. Therefore, the engine uses parts made of high-strength steel (crank and camshafts, engine block).

UAZ diesel engines

Diesel engines come in two types: domestic ZMZ and imported Iveco. The Russian sample corresponds environmental standards Euro-3, while the Iveco engine complies only with Euro-2. Both engines are four-cylinder, cylinder arrangement: in-line, cooling system: liquid.

The Iveco engine has a displacement of 2.3 liters. Fuel consumption on the highway is no more than nine liters. Engine power at 3900 rpm is 116 horsepower. For domestic consumer The Iveco engine installed on UAZ vehicles will not cause difficulties in repair and maintenance.

Fiat cars, from which the engine was borrowed, are very popular in our country. Hence, special problems with availability necessary spare parts will not arise. In addition, a UAZ with such an engine has a good power reserve.

Depending on the vehicle’s configuration, the engine, in addition to its main function, also performs auxiliary functions: this is the power steering drive and the air conditioning compressor. Even under particularly heavy driving loads, everything auxiliary equipment UAZ Patriot will work without problems.

The second version of the diesel engine is the domestic ZMZ. With a volume of 2.25, it has slightly lower characteristics than the Iveco engine. Engine power - 113 horsepower at 3500 rpm. UAZ Patriot, equipped ZMZ engine, develops maximum speed 135 km/h and consumes 9.5 liters of fuel for every hundred kilometers on the highway.

In conclusion, we can conclude that in terms of fuel consumption, the most acceptable option is a diesel engine. But what if you need a UAZ Patriot with highest power, and the price of fuel is in last place, then it is better to give preference to a gasoline engine.

The main unit of any machine is the engine. Pickups, sedans, convertibles, buses, and tractors simply will not be able to perform their direct duties without an engine. That is why great attention is paid to the engine 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 and requires a lot of effort and time.

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

A little history

The first UAZ "Patriot" came off the assembly line in 2005. It was really new UAZ, incredibly modern compared to past models. The manufacturer positioned this machine as safe, reliable and powerful SUV. The design was good for 2005. And if you don't look previous models the design seemed perfect.

In October 2014, the new Patriot was introduced. He received rear stabilizer, touchscreen, glued glass, more attractive appearance, and the bumpers were now attached to the body. However there were big problems with safety. Therefore, already in October 2016, UAZ showed another update. "Patriot" received front airbags, even more attractive and modern appearance. Improved general security and sound insulation of an SUV. Finally, the car got rid of two fuel tanks, which so tormented all owners.

What engines are there on 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 also added a 2.3-liter diesel engine, the output of which was 114 horsepower. It was an Iveco F1A engine. It was installed during the production of the Fiat Ducato car in Russia. This motor was later removed. Since 2012, they began to install the ZMZ-514 turbodiesel. Because of this, the engine displacement decreased by 65 cubic meters. Thus, the improved engine of the UAZ Patriot received the index 2.2d. The same engine remained after the update in 2014. But the gasoline engine has undergone some changes. As a result, its official power became 135 hp. With. On the newest UAZ "Patriot" engines running on heavy fuel can no longer be found. Diesel was abandoned. The gasoline engine was left unchanged.

Diesel engine

Although the Iveco F1A turbodiesel was expensive, it was really reliable motor. In addition, it made it possible to reduce the Patriot’s appetite to twelve liters per hundred kilometers in the city. A calm driver could get ten liters of fuel in the city. Not bad for frame SUV. Moreover, despite less power, when compared with a gasoline engine, made the car much faster. Petrol version was lost after 80 km/h, while the turbodiesel easily accelerated to 120 km/h. This is thanks to the torque, which was equal to 270 N*m, versus 218 “gasoline Newtons”. The diesel also performed much better off-road. It helped get rid of turbo lag. There was always enough traction.

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

According to engineers, most of the problems have been resolved. They changed suppliers of low-quality components, modified the engine together with Bosch. That's how the diesel one turned out reliable engine UAZ "Patriot". Reviews confirm this. Since mid-2012, when they began installing the system Common rail, the engine did not cause any particular problems for the owners. Moreover, in terms of driving qualities and characteristics, the UAZ Patriot engine on the ZMZ diesel engine almost completely coincided with the turbodiesel from Fiat Ducato. Despite this, the manufacturer abandoned the diesel engine from October 2016. Perhaps there was low demand, or maybe this engine was too expensive for the plant, but it is no longer possible to buy a new diesel Patriot.

Gasoline 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 decreased by one N*m, from 218 to 17 N*m. However, when tested on a dyno, the 2015 factory cars produced over 140 horsepower. UAZ inherited this engine from the 24 Volga, albeit with some changes. And in the Volga the declared engine power was 150 horses.

A car with this engine has always been cheaper in the showroom and on the used car market. The advantages include relative reliability power plant. The engine in the UAZ Patriot has good maintainability, and spare parts for it cost almost nothing. This has always captivated people who choose 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 and try to actively accelerate, then a consumption of 20-22 liters per hundred kilometers is guaranteed. And if you consider that a car with this engine simply does not move (acceleration to 100 km/h is 19 seconds), then you will have to turn this engine.

Gasoline engine problems

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

Conclusion

Which perfect engine for "Patriot"? Diesel from Iveco. It runs 500,000 kilometers without any problems. Repairs are cheaper than ZMZ diesel engines. Buy new car? There is simply no choice. The gasoline engine is very reliable, you just have to watch the chain.

Since 2008, UAZ has been supplying Russian market Patriot SUV in two versions with petrol and diesel engines. Initially, the manufacturer used an engine borrowed from Fiat models Ducato. Later, the ZMZ-51432 Euro-4 class engine began to be installed on the UAZ Patriot. The assembly of the model in this design has been completed by this time. But the manufacturer promises to soon resume production of the model with diesel engine.

Features of the diesel modification

Externally, the diesel UAZ Patriot is no different from an SUV, which is equipped with a gasoline power plant. The difference between these two versions of the same model is technical features motors.
The working volume of the diesel engine for the UAZ Patriot is 2.3 liters and 2.2 liters for the Italian and Russian installations respectively. In the first case maximum power equal to 116 hp, in the second – 116 hp. The Iveco F1A reaches a maximum torque of 270 N/m at 2500 rpm, and the Zavolzhsky engine - at 1800-2800 rpm.
The average fuel consumption of a diesel unit is about 9 liters for every 100 kilometers, while a gasoline engine consumes about 13 liters. Among the others important features diesel should be highlighted:

1. Relatively heavy weight, equal to 225 kg. Weight diesel engine regardless of its brand (IVECO or ZMZ) is higher than that of a gasoline installation.
2. There is an exhaust gas recirculation system.
3. Turbocharging is provided. It provides accelerated removal of exhaust gases.
4. The design is complemented by a special pump responsible for pumping fuel.
5. Availability of the system direct injection fuel.
6. The cooling system has a closed design. In this case, the liquid moves in it due to forced circulation.

Due to the large weight of the power plant, the manufacturer had to install reinforced springs in the front of the SUV.
The UAZ company developed a diesel modification of the Patriot with the expectation that future owners will be able to use the car both when driving in urban conditions and off-road. The model is quite economical and provides an adequate level of safety.
UAZ Patriot with a diesel engine is equipped with a Korean-made manual transmission.

Difference between petrol and diesel versions

There is no particular difference between the gasoline and diesel versions of the Patriot. The power of the first engine is 128 hp. with a volume of 2.7 liters. Despite the fact that the diesel engine has slightly less output, this is offset by the increased torque. If gasoline engine maximum value this indicator reaches 217 N/m, then for a heavy fuel unit it is 270 N/m. This difference becomes especially noticeable when the car goes off-road.
It should also be noted that gasoline unit consumes about 12 liters of fuel. As a result, the difference in cost between both models is eliminated within 2-3 years after active use of the car.
In addition, due to the operation of the gasoline engine, the SUV can reach a speed of 150 km/h. For the diesel version, this figure is limited to 135 km/h. Due to the fact that both engines have design differences between themselves, engine compartment Each version is designed differently.
Exploitation diesel units requires compliance with special rules. This is explained by this type fuel is highly sensitive to temperature indicators. To avoid unexpected breakdowns power unit and increasing its service life, the following must be done:

1. At subzero temperatures, the engine cannot be started immediately. Instead, turn the ignition key to the first position and wait about three minutes. At the end of the specified period, you can start the engine. This procedure is performed to warm up the fuel filter.
2. The car must undergo a preliminary run-in. During the first 2.5 thousand kilometers, it is recommended to operate the SUV in gentle modes, reducing the load level to a minimum.
3. Use only high quality diesel fuel class no less than Euro-3.

Traditionally, diesel engines last longer than gasoline engines. However, when extreme driving The service life of the power plant is sharply reduced due to frequent overheating.

Diesel engine maintenance

Any engine, including diesel modifications, requires timely service. This procedure, first of all, involves changing the oil every 8 thousand kilometers. This action eliminates aging of the power plant design. To maintain integrity internal elements For a diesel engine on a UAZ Patriot, it is recommended to use the same brand of oil.
Another important nuance, which should also be regularly paid attention to, is timely replacement timing belt. This procedure is recommended to be performed after 60 thousand kilometers. If this recommendation is not followed, the likelihood of unexpected timing belt breakage increases, which will entail the need to replace the cylinder head, camshaft and rocker arms.
Every 8 thousand kilometers must be replaced fuel filter. And if fuel is used Low quality, then this procedure is recommended to be carried out more often.
Over time in fuel tank x (Patriot uses 2 containers with a volume of 40 liters) sediment appears. To avoid clogging of the diesel engine, they need to be washed every two years.

Improved engine performance

The design features of the diesel engine installed on the UAZ Patriot make it possible to improve its initial characteristics. Chip tuning of this engine involves the following procedures:

1. Modernization of the engine control program. Due to this procedure, it is possible to improve the “cold” start, modes idle move, as well as improve the performance of the power unit.
2. Installation of an additional turbine. It increases the overall engine power. This procedure involves additional modification of the standard software.

Otherwise, chip tuning of the UAZ Patriot consists of carrying out activities that affect other components of the SUV design. In particular, the car doors are complemented various materials, which increase noise, heat and sound insulation inside the cabin.

Advantages of diesel modification

Most owners of the diesel UAZ Patriot pay attention to the following advantages that this model has:

1. 1. High cross-country ability.

The diesel modification of the SUV successfully overcomes clay and sand.

1. 1. Spacious interior and trunk.

The car can easily accommodate up to 5 people.

1. Low maintenance costs.

During the first 50 thousand kilometers you only have to regularly change the main Consumables type oil and fuel filters, oils.

Disadvantages of diesel modification

In 2013, the UAZ company released a restyled version diesel Patriot, in which many shortcomings were corrected. So, the manufacturer has fixed the following problems:

1. Frequent timing break. This was due to the use of low-quality components.
2. Frequent failure of the lubrication system pump. Now this element is located in a new location, thereby reducing the load on it.
3. The valves were replaced with more durable ones.
4. The design and arrangement of elements of the high-pressure pipeline have been redesigned.
5. Drive belt replaced fuel pump to a higher quality one.

Despite the fact that the manufacturer regularly upgrades diesel SUV, he was unable to completely eliminate all the shortcomings that this model has.

1. Poor build.
   Many car owners have noticed this drawback. In particular, they noted the presence strong vibration in the cabin.
2. Poor performance in cold weather.
   This mainly applies to modifications equipped with an engine Russian production. When starting a diesel engine in cold weather, the battery is consumed very quickly.
3. Weak air conditioning.
   The air conditioning on the Patriot is one of the most problem areas. It regularly breaks down and does not always achieve the required level of air temperature in the cabin.
4. Availability of two fuel tanks.

Two fuel tanks are both an advantage and a disadvantage of an SUV, since you can fill quite a lot of fuel at a time, but for this you will have to maneuver at the gas station, because the hatches are located on different sides.
UAZ Patriot with a diesel engine costs more than it petrol modification. However, compared to foreign analogues The Russian SUV wins in terms of price and off-road performance.
