Despite this, the UAZ “Patriot” produced at its facilities is fundamentally different: the SUV turned out to be more “domesticated” and adapted to everyday life.
Characteristics of UAZ "Patriot": fuel consumption, power, speed
After several modifications, the main components and assemblies of the car did not undergo any changes, remaining at the same level: the SUV is equipped with a four-cylinder petrol power unit with a capacity of 128 Horse power, with a volume of 2.7 liters. Fuel is supplied by injection type, the whole system is based on fuel injection directly into the cylinders and complies with Euro-2 standards.
Also available are models with a four-cylinder diesel engine with a capacity of 113 horsepower and a volume of 2.23 liters, an injection fuel injection system. Somewhat earlier, engines of not only domestic production, but also Italian ones, which had 116 horsepower and 2.3 liters of volume, were installed on the UAZ. However, such engines were not installed on the Patriots of 2015 and later.
The vehicle has a standard transmission - mechanical five-speed gearbox gear. Four-wheel drive, and the front one is manually connected by the driver.
Fuel consumption
Happy owners of a brand new crossover of domestic production almost immediately after purchasing it are faced with a not very pleasant problem, which calls into question the feasibility and rationality of this purchase as a whole. The point is that the fuel consumption of the UAZ "Patriot" with a full tank exceeds all conceivable values and does not correspond to the declared by the manufacturer, while the fuel level indicator can show almost complete absence of gasoline after a hundred or two kilometers.
Simple calculations made by the owner of the car, in this case, indicate that the consumption exceeds 20 liters per 100 kilometers, after which thrift comes into play, because of which it remains only to regret that a model with a diesel engine was not taken. In fact, everything is not as deplorable as it seems at first glance. If we calculate the total amount of fuel spent for several thousand kilometers, then real expense fuel UAZ "Patriot" will be about 11-13 liters.
Reasons for the discrepancy
Such a clear difference in indicators is directly related to design features car. The fuel consumption of the UAZ "Patriot" depends largely on the fact that it has two fuel tanks: the main one is used for refueling, and the auxiliary one is filled from the first with the help of a built-in jet pump. It works very slowly, so the process of filling both containers takes at least 15-30 minutes. During the start of the movement, gasoline from the auxiliary tank enters the main tank; when stopping, everything happens in the reverse order.
Instrument panel gauge readings
The fuel consumption of the UAZ Patriot may be incorrect due to one more reason. The sensors installed in the tanks show a non-linear change in the fuel, since the tanks themselves are straight. The devices themselves are VAZ, they were created specifically for the "Lada", the tanks of which are of a slightly different shape and taper upward, expanding downward. Accordingly, in the upper part, the level of gasoline in them changes several times more slowly.
In UAZ, on the contrary, the gasoline level drops linearly, and this happens several times faster. Accordingly, the sensors will not show the actual fuel consumption for the UAZ Patriot. Gasoline, even if it is quickly wasted at the very beginning of the journey, will actually be saved.
Distortion of data by the on-board computer
The reason for this lies in the fact that initially the device itself is not subjected to any calibration. The opening time of the injectors enters the ECU, and from this information it calculates the fuel consumption. Actually, this is the reason: depending on the model of the injection system, the performance of the injectors also changes. In order for the computer to give real information, it is necessary to calibrate it. It will be most accurate on full tanks, however, it can be done at idle speed.
In this case, the fuel consumption of the UAZ "Patriot" is regulated as 1.5 liters / hour, while the computer outputs a figure of 2.2 liters. The average is correct. It is advisable to connect a calibrated BC of a similar car model before starting measurements, while changing the mileage calibration.
Car tire pressure
Fuel consumption largely depends on the level of pumping of the wheels, especially the rear ones. It is advisable to regularly check the tire pressure: the front should be slightly less. In addition, consumption may increase due to running hubs. front axle... The gearbox of the front axle at negative ambient temperatures is blown by a flow of cold air and rotates without much load, which will lead to the creation of additional resistance between the unheated and non-liquefied oil. To avoid this problem, it is advisable to use only a high quality synthetic lubricant, the viscosity of which will not change at low temperatures.
In addition, you can save fuel with regular use of the car by driving in high gears, constantly monitoring the number of revolutions. Care must be taken that they do not fall below the minimum mark of 1500 rpm.
What is the fuel consumption of UAZ "Patriot" in reality
Considering all of the above, we can conclude that not everything is as sad as it seems at first glance. For UAZ "Patriot" fuel consumption (reviews of numerous owners this car this is confirmed) is about 13.5 liters per hundred kilometers within the city limits. Most drivers note that when driving on the highway, consumption is about 10 liters per hundred kilometers. With an increase in the speed of movement, it can increase to a maximum of 11.5 liters.
For the diesel version of the "Patriot" when driving on a country road, the consumption will be about 9.5 liters. In urban areas, it changes to 12-13 liters. The turbo diesel engine will consume about 15 liters off-road. Consumption may increase accordingly when using an air conditioner, all-wheel drive, stove or with flat tires.
Despite all the advantages of the diesel "Patriot", they acquire it, according to statistics, only in 5% of cases. The main deterrent factors are the high cost, the impossibility of transferring the car to gas and the complex maintenance of the engine. In addition, it is also repelled by the high noise level and the almost complete absence of sound insulation.
The Patriot SUV is the flagship of the well-known Russian UAZ brand. Serial production of the car began in the summer of 2005, after its predecessor, UAZ "Simbir" (1997-2004), was discontinued. The base gasoline engine UAZ Patriot - .10, as well as the diesel ZMZ 514.32, went to the car from its predecessor.
In addition, for several years (2008-2012) the Ulyanovsk Automobile Plant (UMP) produced the original version of the Patriot model, equipped with Italian diesel engine IVECO F1A, which many experts consider to be optimal for this car.
INTERESTING! Currently, ZMZ (JSC Zavolzhsky Motor Plant) is completing the development of a new 2-liter car engine with a capacity of 140-150 liters. with. (torque 300 Nm).
In addition, it is planned to produce a more powerful power unit equipped with a turbocharger. New motor will fully comply with the mandatory international standards "Euro-5".

Description
The power unit IVECO F1A is an example of the family of commercial engines of the international corporation Iveco.
The engine is designed for installation in small cars. Like all commercial motors, it has a large service life and a high degree of maintainability. These results are achieved by increasing the weight and height of the motor.
Structurally, it is an in-line 4-cylinder diesel engine designed as a "sandwich". It is equipped with a fuel supply system of the type Common rail(microprocessor control with forced fuel injection) with common rail and turbocharged with intercooling and exhaust gas recirculation.
- The engine block has a thicker wall and is made of ductile iron. In its lower part, the main bearing caps are fixed. crankshaft, structurally combined into one strong supporting part (crankshaft bed). An oil pan made of steel is attached to this part. This type of bed plate design provides the entire engine with increased rigidity, which is essential for commercial vehicles on which this power unit is installed. Their weight can reach 6 tons.
- Of particular interest is the original design of the cylinder head (cylinder head). It differs from conventional ones in that the camshafts of the gas distribution mechanism (timing) are assembled in a separate housing, which is installed on top of the cylinder head. This design led to an increase in the height of the motor, but made it possible to quickly replace the camshafts in case of wear (without disassembling the timing).
- Inlet camshaft The timing belt is driven by a toothed belt with automatic system tension. The exhaust camshaft is driven by a chain that connects it to the intake shaft. Both camshafts have three bearings and are tunnel-mounted.
Maintenance
One of the advantages of commercial engines is their unpretentiousness and simplicity. Maintenance. The engine does not require adjustment of the timing valve clearances, as it is equipped with special hydraulic compensators.
Changing the engine oil is required after every 20,000 km, and the air filter is changed no earlier than 80,000 km of the distance traveled. Interestingly, in Italian-made cars, it is recommended to change the engine oil no earlier than 40,000 km. At the same time, the volume of the poured oil was increased to 7 liters.
Answering the question: “What kind of oil to pour into the engine?”, Iveco engineers recommend using Urania Daily and Urania LD 5. According to domestic experts, it is also possible to use engine oils of SAE 15W40 or SAE 5W30 specifications.
Malfunctions
| FAULTS | CAUSES |
|---|---|
| Increased fuel consumption | "Aging" of the oxygen sensor; Ÿ the engine control controller has accumulated false data; malfunction of the knock sensor. |
| The engine is losing power. | misfire due to a defect in one of the cylinders; lean fuel mixture; one or more injectors are damaged. |
| Unstable engine idling | bounce of contacts of the throttle position sensors; wear of elements of the fuel supply system; unaccounted for air leaks or incorrect calibration of the air flow sensor. |
Tuning
There are many options for tuning the UAZ Patriot IVECO F1A engine. With their help you can:
- increase engine power;
- increase the amount of torque;
- reduce fuel consumption, etc.
Among the numerous types of tuning of the IVECO F1A power unit, UAZ Patriot owners most often choose:
- Chip tuning of the UAZ Patriot engine through the OBD2 diagnostic connector
The IVECO F1A motor is controlled by an electronic control unit (ECU) of the BOSH concern, assembled on the basis of a Motorola processor. To connect to it, use the most secure full access mode. For this, a BDM interface is used, which is specially designed for rebooting and debugging Motorola processors.
As a result of software update and high-quality debugging, the following results are obtained: increase in power and torque value by 20 ... 25%; the ability to programmatically or physically disable the EGR valve - recommended for vehicles with high mileage.
- Tuning the UAZ Patriot engine without interfering with the work of the standard software.
Tuning the UAZ Patriot engine using Rambach technology, unlike other methods that involve replacing the engine control algorithm, does not affect any of the factory settings, but only corrects or complements their work as an external device.
An external POWERBOX electronic unit is connected between the sensors that control the operation of the power unit and the ECU. During operation, this unit, receiving signals from the sensors, corrects them and then transmits them to the control unit. In accordance with the received signals, the standard vehicle ECU corrects the operation of the motor, improving its performance.
Installation of the POWERBOX unit allows you to: increase power and torque by 30%; reduce fuel consumption by 12%; to adapt the operation of the fuel supply system to the quality of domestic diesel fuel.
Motor for 469 models
Engines for UAZ 31514 are available in several versions. By type of fuel, they are divided into gasoline and diesel. Many characteristics of the car, including fuel consumption, depend on what engines are installed on the UAZ.
For example, a 2.4-liter UAZ gasoline engine of the ICE 210.10 type has the following characteristics: power - 91 liters. with., fuel consumption - almost 12 liters per 100 km. UMP 4178.10 engines of the same volume have 87 horses and fuel consumption increases by one and a half liters.
General characteristics of engines
The main suppliers of engines for UAZs are the Ulyanovsk Motor Plant and the Zavolzhsky Motor Plant. UMP became famous for being practically the only manufacturer of engines for cars in Russia off-road... All modern engines produced from the assembly line of the plant meet Euro-4 standards.
ZMZ produces more than 80 different modifications of engines ranging from 2.2 to 4.6 liters. The units of this plant are installed both on small off-road vehicles and on buses of domestic and foreign companies.
There are other types of engines that are installed on UAZ 31514 vehicles:
- UMP 4218.10 with a volume of 2.8 liters (gasoline);
- ZMZ 410.10 with a volume of 2.9 liters (gasoline);
- UMP 420 with a volume of 2.4 liters (gasoline);
- ZMZ 514 with a volume of 2.2 liters (diesel);
- Andoria 4CT90 with a volume of 2.4 liters (diesel).
The Andoria engine installed on UAZ 31514, Iveco and UAZ Patriot vehicles is produced not in Russia, but in Poland. These engines are in demand not only at the Ulyanovsk Automobile Plant. They are also installed on other Russian-made machines.
Base motor UMZ 421.10 for UAZ
Base UMP engine 421.10 with a carburetor system, having a volume of 2.9 liters, runs on gasoline. Has a gas exhaust system. It can operate at temperatures from -50 to +50 degrees Celsius. The 4218.10 unit became a modification of such a motor.
The main difference between the UMP 4218.10 is in the gas exhaust system, which is not tuned. This simplifies the installation of the engine on UAZ vehicles, even with a wagon-type body. Currently, motors of this series have several modifications.
UAZ 39626 and Patriot motors
The UAZ 39629 vehicle, in other words "sanitary", is most often used to transport patients and is available in most medical centers. It is widely used both in metropolitan areas and in rural areas. These machines are equipped with three different engines.
- ZMZ-402.
- UMZ-4178, similar in characteristics to the first, differ only in manufacturing plants. These motors have a displacement of 2.4 liters and a power of 92 horsepower.
- UMP 4218 with a volume of 2.8 liters and 98 liters. with. under the hood.
UAZ Patriot cars are equipped with a four-cylinder four-stroke engine of the ZMZ 409.10 series. The valves are top-mounted, and the cooling is liquid. The ignition system of this engine is microprocessor-based, fuel injection is distributed. The diesel engine ZMZ-51432 for the UAZ Patriot is a must.
Diesel fuel is more economical and practical
In Russia, diesel fuel is gradually becoming fashionable, but until recently the production of diesel engines was only in the plans. Foreign diesel engines for the UAZ Patriot, as a rule, did not fit, and attempts to aggregate them were abandoned.
Reviews of the UAZ Patriot diesel engine of the foreign company IVECO F1A end with negative reviews about its quality. Maybe because for Russian cars Ulyanovsk or Zavolzhsk motors are more common. The volume of the overseas engine is 2.3 liters, and the power is 116 horses. The Italian engine is noisier and less powerful. However, owners of a Patriot with a foreign engine will appreciate good traction and fairly economical fuel consumption - a little less than 10 liters per 100 km.
Not so long ago, the Zavolzhsky Motor Plant began to produce an engine that runs on diesel fuel, for SUVs UAZ Patriot and UAZ Pickup. The ZMZ-51432 motor is small-displacement, its volume is 2.2 liters, it complies with the Euro-4 standard. The engine has a maximum power of 114 horsepower, 3500 rpm and low consumption fuel.
There are many original parts, thanks to which energy and economic indicators have increased. At the same time, emissions of harmful substances have been reduced: by half in comparison with engines corresponding to "Euro-3". The noise level has decreased in accordance with the requirements of the standard.
Characteristics of the UAZ 469 motor
UAZ 469 has a 4-cylinder engine of the UMZ 417 series with a volume of 2.5 liters. The power of such a motor reaches 75 horses, the location of the valves is upper. The fuel supply system is forced. Closed cooling system, liquid with forced circulation. The nuance of this engine is a fairly decent fuel consumption, up to 16 liters per hundred.
Two different modifications of this engine are installed on the UAZ 469 for two different purposes. UMP 4178 - for ordinary civilian models, UMP 4179 - for military ones. The difference between "military" motors is that they are equipped with a sensor-distributor and high-voltage shielded wiring. In addition, they have a special place for heating.
A distinctive feature of the UMZ 417 series engine is the special design of the combined cylinder block and the upper part of the crankcase into a single whole, made of high-strength aluminum alloy. The cylinders are wet removable liners and are cast in gray iron. The wear resistance of the liner is ensured by the acid-resistant cast iron at the top.
Aluminum cylinder head assembly for the UMZ 417 engine
The head of the block is common to all cylinders and is made of aluminum alloy, just like the pistons. The five-point crankshaft is made of magnesium cast iron.
Hunter engine features
The UAZ Hunter, which replaced the UAZ 469 in 2003, is equipped with both a gasoline and a diesel engine. The differences between a gasoline engine and a diesel engine for Hunter are insignificant.
The basic power unit for this car was a four-cylinder ZMZ 409.10 with a volume of 2.7 liters. The engine is equipped with a 16-valve mechanism and multipoint fuel injection. The power of the unit reaches 128 horsepower. The engine's appetite is up to 13 liters per 100 km.
The diesel engine for the Hunter brand ZMZ 5143.20 has four cylinders arranged in a row. The volume of the engine is 2.2 liters, there is a fuel injection system. In terms of diesel economy, the engine is largely superior to its gasoline counterpart. It requires a maximum of 10 liters per 1000 kilometers. But the dynamics suffers slightly, diesel in this regard is slightly inferior to gasoline.
The reliability of the engines on the UAZ Hunter car is the highest. The main thing, as the developers convince, is the correct care and timely repair of the failed parts. The motors show themselves well in off-road conditions in terms of traction development and are not capricious in the harsh Russian winters.
An example of tuning a motor
Tuning engines installed on UAZ vehicles is not so easy to do. Any tampering with the motor can lead to a decrease in traction force. And the models of many engines are outdated, so too many innovations and changes can play a cruel joke with them.
Certain mechanisms and systems can be modernized, of course. Changes in piston group must be carried out with caution, guided by the instructions. Piston rings change to forged, better quality and durable. The well-known company "Goetze" produces just such rings. If desired, you can install other details, but the work will require a professional approach and the appropriate tool.
It is possible to balance the UAZ 31514 crankshaft at home only with a flywheel. By placing the crankshaft on one of the ribs of the T-plates, determine the heaviest point. The crankshaft will roll over the plates until it stops at the heaviest point down. From this point, it will be necessary to remove a small layer of metal, periodically checking the result.
The timing has a number of features, so it is better for non-specialists not to change its design. Moreover, the camshaft is tuned only in sporting interests. If something goes wrong, engine performance will only deteriorate.
The intake and exhaust manifolds on the UAZ 31514 are tuned by many car owners. The first priority is to eliminate the step between windows and collectors. The holes are often not aligned.
Notches inside the manifold bore are removed by rough grinding or more careful polishing. This modification will improve engine performance in terms of uniformity of cylinder filling and improve its performance.
UAZ Patriot engine, which was installed on the model of last year, remained on the restyled UAZ Patriot 2015. There have been no major changes, customers are offered a choice of gasoline and diesel engine options. Both engines are ZMZ. The diesel engine ZMZ-51432.10 CRS with a Common Rail fuel supply system and a 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 tell you in detail about the characteristics of both motors.
So, gasoline engine UAZ Patriot ZMZ-409, it is a 4-cylinder, 16-valve, in-line, with an integrated microprocessor-based fuel injection control system. Injection injection fuel flows into the intake pipe. Ignition system with coils that supply current to the spark plugs screwed vertically in the center of the combustion chambers. There are even special wells in the cylinder head cover for this. Microprocessor system with an electronic engine control unit, automatically controls the ignition timing.
The cylinder block of the power unit is cast from a cast iron alloy, the cylinder head is aluminum, with two camshafts and hydraulic valve lifters. Timing chain drive... At the same time, the chain device of the gas distribution mechanism of the UAZ Patriot engine is very complex, since it consists of two chains connected through an intermediate shaft. Plus there are two chain tensioners with sprockets. This whole construction is weak point the entire engine, since insufficient tension, a breakdown of the hydraulic tensioner, leads to an increased noise of the UAZ Patriot engine. In addition, hydraulic lifters often fail, which leads to a knock in valve mechanism.

Naturally, the manufacturer does not name objective data on the fuel consumption of the gasoline Patriot in urban conditions. The reason is clear enough high consumption fuel can frighten off buyers. If you want to save on fuel, then buy a UAZ Patriot with a diesel engine, which we will talk about further.
Diesel UAZ Patriot collected at the same Zavolzhsky Motor Plant. Inline 4-cylinder, 16-valve power unit with two camshafts. Timing chain drive with hydraulic tensioners. The valve train has hydraulic lifters. The cylinder block is cast iron, the block head is aluminum, there is a turbocharger.

Have diesel unit Patriot has a problem with the 5-speed mechanical box gear that does not allow you to use all the advantages of the motor. When driving on the highway, the diesel engine simply lacks the 6th gear. Although off-road perfect option... By the way, the box for gasoline engine has a gear ratio of the main pair of 4.11, for a diesel engine 4.625. When purchasing, it is recommended to install preheater, otherwise problems with starting this engine will begin in winter.
Throughout its history of production, UAZ received several engine options. Gasoline engines had an engine capacity of 2.7 liters, but the diesel version was 2.2 and 2.3. The bulk Vehicle received power units produced by ZMZ, but the diesel version was equipped with an Iveco F1A engine.
Specifications
Before starting to consider malfunctions and repairs of power units for the UAZ Patriot, you need to know what technical characteristics they have. Many motorists are quite familiar with ZMZ units, but the Iveco engine is extremely rare.
Consider which specifications for power units installed on the Patriots:
ZMZ 514.32
Iveco F1A
Gasoline options ZMZ 409
On UAZ patriot, modifications of the original engine were installed:
- ZMZ 40905.10 is an analogue of 40904.10, compliance with the Euro-4 environmental standard. Power 128 HP
- ZMZ 40906 is an analogue of 409.10 with a new CPG, new gaskets, MAP, complies with the Euro-5 environmental standard. Power 135 HP
All cars were equipped with a 5-speed manual transmission made by Dymos (Korea). Transfer case electro-mechanical, 2-stage with an electric drive (I-1, II-2.542) from Dymos (Korea).
Service
Maintenance of the engine is expected after the expiration of 15,000 km. Many vehicle owners are interested in the answer to the question - how many liters of oil must be poured into the engine during servicing? And the second question - which oil is suitable for filling / topping up the UAZ Patriot engine?
Petrol engine
So, the engine holds 7 liters of engine oil, but when replacing, only 6 liters are required. The main oils recommended by the manufacturer and motorists are semi-synthetics with the markings: 5W-30, 5W-40, 10W-30, 10W-40, 15W-40, 20W-40.
The maintenance card is no different from the 409, and looks something like this:
- 1000-2500 km or TO-0: oil change and oil filter.
- 25,000 km - TO-2: oil change, oil filter.
- 40,000 km - TO-3: change of oil, oil and air filter, spark plugs, high-voltage wires, adjustment of valves.
- 55,000 km - TO-4: oil change, oil filter, fuel filter, replacing the timing chain and alternator belt.
- 70,000 km - TO-5 and subsequent: oil and oil filter change. Every 20,000 km it changes - the fuel and air filter, valves are adjusted. Every 50,000 km of run - replacement of the timing chain.
Diesel engine
Maintenance of the UAZ Patriot diesel engine is somewhat different from the gasoline one. So, the answer to the question - how much oil to pour into the engine will be different. The volume of oil required for a change is 7 liters, and 7.4 liters fits directly into the engine.
Maintenance chart for diesel engine variants of the UAZ Patriot:
- 1000-2000 km or TO-0: oil and oil filter change.
- 8000-10000 km - TO-1: replacement of oil, oil and air filter, spark plugs, high-voltage wires, fuel fuel.
- 25000-27000 km - TO-2: oil change, oil filter.
- 45000-50000 km - TO-3: replacement of oil, oil and air filter, spark plugs, high-voltage wires, valve adjustment.
- 65,000 km - TO-4: replacement of oil, oil filter, fuel filter, replacement of the timing chain and alternator belt.
- 90,000 km - TO-5 and subsequent: oil and oil filter change.
Change of oil
Oil change in the UAZ Patriot engine is carried out by analogy with all power units manufactured by ZMZ. First, you need to drive the vehicle onto a lift or pit. Then, the drain plug is unscrewed, and while it flows lubricating fluid, the oil filter is changing.
The subsequent procedures are standard - new oil is poured.
Engine malfunctions and repairs
As practice has shown, with diesel engines- a lot more problems than with gasoline options. Consider the main malfunctions that occur on the ZMZ 514.32 and the Iveco F1A engine:
- Vacuum pump failure.
- Cut off the oil pump drive or intermediate shaft.
- Unscrewing the plug KV.
- Break, jump of the timing chain.
- Breakage of the phase sensor plate.
- Depressurization of the intake pressure line.
- Low pressure in the fuel rail.
- Slow and insufficient engine warm-up in winter.
- Oil and grease deposits in the intake manifold
- Black smoke in the exhaust.
As for the gasoline version of the engine, the problems are the same as for any ZMZ 409. The eternal problem with the thermostat, which every motorist treats as best he can. The chain of the gas distribution mechanism can last about 200 thousand km, but it happens that it does not take care of even 100 thousand km, as you are lucky.
On some vehicle models, it was noticed that injectors were quickly failing. It is easy to repair the malfunction - replace all injected elements.
Engine tuning
The problem with most UAZ vehicles is too expensive mechanical tuning, namely expensive spare parts. Therefore, most owners stop at the very simple version- chip tuning. There are two types of software revision for the UAZ Patriot - chip tuning for consumption and power. As practice shows, specialists, in most cases, reduce the expense, which is significant.
Output
On the UAZ Patriot, reliable power units ZMZ 409 were mainly installed. Of course, one should not exclude diesel versions - ZMZ 514.32 and Iveco F1A. It is quite simple to repair power units, but often motorists prefer a car service for such operations. The revision ends with the fact that chip tuning is done to reduce consumption or increase power.
