Increased power engines Ulyanovsk motor factory began to produce since 1997, first DVS Cylinder diameter of 100 mm became carburetor UMP 4215, and in the 1998 Ulyanovsky developed a new injector motor with a capacity of 110 liters. p., corresponding to the norms of Euro-2. Gasoline engines Umz 4216 experienced parties began to be issued since 2003, and soon they were launched in a series.
Model 4216 is installed on cars gas, this power unit is equipped with commercial cars "Gazelle". In 2008, the Ulyanovsky engine was improved, and he began to comply with the norms of Euro 3, and since 2012 he was brought to the EURO 4 standard. In 2013, hydraulic compensators were used on this engine, from 2014, the Ulyanovsk plant began to assemble Evotech motors The volume of 2.7 liters, which is installed on the commercial car "Gazelle Business" and "Gazelle Nex".
The prototype of the engine of the Ulyanovsk Motor Plant is the Motor ZMZ-21 - it has a fundamentally the same design:
- aluminum cylinder block;
- top Layout of Valves;
- gear drive of the gas distribution mechanism;
- aluminum rods;
- the lower arrangement of the camshaft;
- two valves per cylinder.
A similar configuration has even an oil crankcase - it is also steel, stamped, with recesses in front and rear. 
As well as on the ZMZ-21, on the Ulyanovsky engine, the pistons with connecting rods are connected using "floating" piston fingers - landing the pistons is made on the "cold", copper (bronze) sleeves are pressed in the upper bushings.
On all engines of UMP with a diameter of cylinders of 92 mm in the cylinder block (BC) are installed "wet", removable sleeves. In a block with a piston diameter of 100 mm (model UMP 4215, 4213 and 4216), the sleeves are pressed on special equipment, and during repair, they will not succeed in repair, therefore, with a significant wear of the cylinders, BC replacement is required.
Engine 4216 consists of the following details:
The gas distribution mechanism (camshaft) is activated from crankshaft After a couple of gears. Camshaft camstered through pushers and rods raise and lower the rockers, which in turn are pressed on intake and exhaust valve. Due to the valves, the cylinders filling the fuel and air mixture occurs, the engine cycle occurs.
By car Gazelle Business Engine UMP 4216 is equipped with electronic system Control, which includes:
- mikas control unit;
- ignition module;
- high-voltage wires with tips;
- sensors - throttle valve, k / shaft and p / shaft, absolute pressure, detonation;
- wiring;
- regulator idle move;
- fuel injectors.
Motor 4216 is a four-stroke, with a row arrangement of four cylinders, 8-valve. DVS is intended for operation on gasoline AI-92, it is allowed to use better fuel, for example, gasoline AI-95. The technical characteristics of the engine modification of UMNS-42164 (Euro-4) are as follows:
- volume - 2890 cm³;
- diameter of standard pistons - 100 mm;
- compression ratio (compression in cylinders) - 9.2;
- piston stroke - 92 mm;
- power - 107 liters. from.;
- system cooling in DVS - Liquid (tosol or antifreeze).
Block and GBC are distinguished from aluminum alloy. The engine of the first completeness weighs 177 kg, the power unit itself is included in the motor package, it also installed hinged equipment:
- starter;
- generator;
- intake manifold (receiver);
- ignition module with wires and tips;
- drive belts;
- water pump;
- crankshaft pulley;
- basket and clutch disc;
- esud sensors.
According to the factory standards, the fuel consumption of "Gazelle" with Ulyanovsky DVS is 10 l / 100 km on the highway outside the city, in the mixed mode, it is equal to 11 l / 100 km. In practice, gasoline is usually consumed more, much depends:
- from the workload of the car;
- speed mode;
- operating period (in winter to heating the fuel is spent more).
The modification engine of UMP 42164-80 is equipped with hydrocompensators, this motor is equipped with a commercial car "Sable Business" and "Gazelle Business". From the standard motor 4216 model 42164-80 differs by a little - other, special stalls are installed on this engine, at the top of which compensators themselves are attached. 
The crankshaft 4216 consists of four connecting rod and five roof connecting skeins, has diameters:
- indigenous shek - 64 mm;
- schittered necks - 58 mm.
All necks are installed in two steelbobitious liners, the factory tolerance of the sizes of the crankshaft - 0, 013 mm. During the repair of the Ulyanovsk engine, the micrometer is measured by indigenous and connecting rod cervix - when their wear is more than 0.05 mm, the shaft is subject to mandatory grinding. The diameter of the piston fingers is 25 mm, the fingers are installed in the bronze bushings of rods. Over time, both the fingers and sleeves themselves can be exhausted, in the event of the appearance of hypers in the connection, the part is subject to replacement.
The crankshaft in the cylinder block is mounted on the supports of the lids, which are tightened by bolts with a certain effort. Each cover has its place - they can not be confused by some places, especially since to pick up from another BC. Also, the covers need to put the lock to the lock - if it is wrong to install them, the crankshaft may not scroll (it will be lit), and even if the shaft is scrolled, the engine will quickly fail.
Motor resource 4216, declared by the manufacturer - 250 thousand km, but often the engines failed before the deadline. Often emerging problems of DVS:
- the leakage of motor oil;
- increased oils of oil through piston rings:
- the knuckle of valves, which is sometimes difficult to eliminate;
- overheat;
- failure of various sensors.
Different breakdowns can be premature for different reasons:
- the driver is disturbed by operating conditions - the motor overheats due to the overload;
- no maintenance standards are not respected;
- the car is operated in severe road conditions.
Unfortunately, in the engines of UMS, marriage is often found, but the Motors of ZMZ are not insured. If the engine 4216 troit (twitch), the cause of the malfunction can be both the engine itself and breakage in the ECM. To determine the reason for the occurrence of a defect, it is necessary to diagnose in DVS. 
Reviews of car owners
About the engine UMP 4216 There are the most controversial reviews - some owners of "Gazelle" "UAZ" engines praise and believe that they are:
- possess good travelers;
- moderately consumed fuel;
- inexpensive, moreover, simple repair.
Indeed, the engine UMP 4216 is very simple, especially since it has a significant similarity with the engine of DVS ZMZ-402. Design power aggregate Many drivers are familiar, and repaired such an engine can almost be in the field. Some complexity for car owners is an electronic equipment of the motor - still the injector is somewhat more complicated by the carburetor device.
From the owners of "Gazelle" with UAZ motors, you can also hear extremely negative responses:
- the engine is inclined to overheating;
- often fail the sensors, so the motor begins to told and do not go;
- the engine consumes oil, it flows, from where it is only possible.
Unfortunately, a lot of marriage comes from the Ulyanovsk plant, and mostly complain about the Ulyanovsky engine those drivers who were caught defective internal combustion engine. There are several characteristic factory "flashers", which are often found quite on UMP 4216:
- the intake manifold cracks and begins to suck air;
- does not provide the right oil pressure pump;
- the electromagnetic cooling clutch is refusing to operate, and the motor begins to overheat.
Drivers of such unsuccessful "Gazelles" note that the engine has to often "focus with a file". Also noticed - if the motor is to go completely with your own hands, the breakdown in it occurs significantly less often, the main thing is to assemble the engine using original details Good quality.
Engine repair UMP 4216
During the operation of Gazelles with the engine UMP 4216, various breakdowns arise, one of the most common problems - overheating of the motor. If the cooling system "Air", from expansion tank Begins to throw out toosol (antifreeze). As a result of overheating, the blocking of the block head is often punched - to change the PGBC as a whole is easy, and often drivers independently produce such repairs.
But the problem in the case of overheating consists in the other - often from the high temperature on the pistons the partitions are burst, the piston rings "lie". To replace the pistons or rings, it is not necessary to remove the engine, just throw the block head and the oil pan.
Caparem UMP 4216 is needed in cases when:
- worn or damaged sleeves of the cylinder block;
- knocking (wears) crankshaft;
- low oil pressure in the system, and the replacement of the oil pump does not give positive results.
Often the Ulyanovsky engine is overheated, and drivers take various measures to get rid of it unpleasant and dangerous for the internal combustion. Many owners of "Gazelle" are installed instead of a regular aluminum copper three-row radiator cooling - copper more efficiently becomes the antifreeze. Another overheating method is to install a cooling electric fan with a toggle switch, which is located in the driver's cab. At the moment when the sensor arrow starts to show the critical temperature of the coolant, the driver forcibly includes a fan, and the temperature regime comes to normal.
In the case of the acquisition of "Gazelle" with an unsuccessful engine, car owners seek to get rid of the power unit, replacing it into the engine of another model. On the replacement you can consider a lot different optionsBut most often the owners of the commercial car put the Motors of ZMZ-405, it is this engine for a number of reasons:
- volga motor does not capricious - well "digest" Russian fuel, it is infrequent;
- relative to imported force aggregates (Cummins, Toyota, Nissan) ZMZ-405 is inexpensive;
- for installation ZMZ. Requires minimum alterations.
On the Machines "Gazelle Business" recently, the Kamminz Turbodiesel is regularly installed, but the owners of machines with UMP-4216 this motor as a substitution is almost never considered:
The advantage of the ZMZ-405 (or 406) is still the fact that secondary market A lot of second-hand motors are sold in a normal, working condition, and the price of them below the new DVS several times. True, when buying a used unit, there are no serious guarantees - you have to believe the seller for the word. But even if the 405th and requires a small repair (replacement of chains or piston rings), all the same, its purchase, along with repair, is much cheaper than the acquisition of an expensive import engine. Even minus imported internal combustion engine is that if he is serially on the Gazelle, he was not installed, it will have to purchase it together with the gearbox or pumped out of the fitting of the Gazelvskaya KPP to a new motor.
Now the popular and common commercial cars of the brand gas are equipped with Motors UMP, produced at the Ulyanovsk engine factory.
A bit of history
The Ulyanovsk Motor Plant is originated from the distant 1944, and only in 1969 the enterprise produced the first engine of the GAMP brand. Up to sixty-ninth year, the plant was engaged in the production of small UMW-451 engines and their components.
Since the release of the first motor, they faithfully serve on trucks, Auto S. increased patency, on small buses. In 1997, autogas became the main consumer of the motors, which worked as aggregates of UMP Most models of the Gazelle line.
Construction features
At the moment there is a wide range of DVS model Row UMS, whose installation is carried out on different models cars "Sobol", UAZ, Gazelle. Installed engines have a number of common features, but may differ in some details and principles of work:
- Carburetor and injection.
- Four-cylinder with inline location.
- With a capacity of 89-120 liters. from.
- Environmental standards "Euro-0", "Euro-3", "Euro-4".
All engines are light, small and reliable. They are distinguished by the available cost.
One of the features of the engine can be called the original design of the block of cylinders, cast from aluminum, with climbed gray cast iron sleeves. The crankshaft shafts of motors of all modifications in the manufacture of the injection of indigenous and connecting rods of high frequency currents. Self-sufficient seals the back of the crankshaft.
Modifications of model range
Motors UMW have two line of power units designed to equip various cars.
Cars of the Gazelle family are completed next models: Umz-4215; Umz-4216; Umz-42161; UMP-42164 "Euro-4"; UMP-421647 "Euro-4"; UMS-42167.
The main part of the engines is published in several variations that differ in their complete set, power and economy indicators. At the moment, the production of gasoline operating aggregates has ceased octane number 80.
All engines are designed under 92 and 95 gasoline, as well as with the possibility of working per gas.
This review is dedicated to the power plant UMP-4216, its characteristics and properties will be detailed.
pros
The advantages of the motor will rightfully include the maximum torque on low revs, excellent specifications, as well as ease in the maintenance of nodes and aggregates. The 4216 engine became the first domestic device that has a warranty period when installing gas equipment on it.
Modernization
The unit is equipped with a microprocessor injection management system fuel mixes and ignition systems. Detonation I. oxygen sensors The 4216 engine directly affect the operation of a complex electronic control system and an aggregate as a whole. To change the economic characteristics and increasing competitiveness, the following constructive additions were made to the power plant:
- For increase operational indicators The compression ratio in the cylinders was increased.
- To reduce oil consumption, upgraded the cutter gases removal system.
- Motor reliability is provided by applying advanced parts and materials.
At the same time, the unit has not changed in terms of overall parameters and standard characteristics (the volume of the work is 2.89 liters, the stroke of the pistons, the size of the cylinders).
For the first time, the GAZ-4216 engine began to be completed by the details of imported production, which only increased the quality of work and durability in operation. Candles were installed on the power unit and fuel injectors produced by Siemens, as well as the sensor position of the German throttle production position.
Major malfunctions UMP
Previously please frequent breakdown The engine was damage to the intake manifold. As the developers claimed, a collector was installed on the engine 4216, made of fragile material. But already in 2010, this deficiency was corrected by the use of better material.
In the cooling system, the flaw was also discovered.
On the average engine speed and when the car is moving at a speed of 60 km / h, the temperature of the coolant was normal, but it was worth only to reduce the speed or to get into the road plump, as the engine 4216 rapidly gained the temperature, down to the boil the coolant. The reason was rooted in which included the fan of forced cooling.
Technical specifications
The engine operates on AI with the number of octane 92 and 95. Four cylinder, with a row placement of the cylinder, eight-block. Cylinders have the following working order - 1243. The diameter of it is one hundred millimeters, and the movement of the piston is 92 millimeters. The engine volume is 2.89 liters, it develops the power of 123 "horses" at four thousand revolutions. Motor - 8.8. The maximum torque is 235.7 at 2000-2500 turns per minute.
Gazelle with the engine UMW-4216 can develop maximum speed 140 kilometers per hour, which for such a class of auto is a good indicator. Fuel consumption depends on car load, driving manners and road conditions, but in general it looks like this: at a speed of 90 kilometers per hour - 10.4 liters. When moving at a speed of 120 km / h - 14.9 liters.
Supply system
Consists of a fuel supply device and various fuel lines, nozzles, fuel and air filters, air supply and receiver nozzles, idle regulator.
Fuel control is carried out using a variety of sensors: the temperature element of the injected air, the position sensors of the crankshaft and distributional shafts, absolute pressure detail, throttle valve position.
The feed control system is also equipped with an oxygen indicator. The latter is installed in exhaust system Before the neutralizer. Engine 4216 (injector) for greater reliability and durability should work only on high-quality gasoline, taking into account the regular replacement of fuel filters and periodic diagnostics fuel equipment. Motorists say that with competent operation, the total resource of the power unit can reach 500 thousand kilometers. Injector installations are also different (in mind the engines of ZMZ 405 and 406).
Gas distribution mechanism
In 2010 on petrol motor The process of upgrading the gas distribution mechanism has undergone. In general, it affected the change in the camshaft fist profile, which contributed to an increase in the stroke of the valve per millimeter. These innovations were needed to improve the sustainable work of the unit at idle, as well as to achieve the norms and requirements of the EURO-3 standard.
The springs of the valves did not undergo changes, and this led to the fact that the existing force on the springs crossed the norm, and now 180 kgf was equal. When installing a regular set of rods on new engine Prior to reaching the state of the heated engine, the stuffs of hydrocompensators were listened.
In order to prevent this problem, the springs force should be changed by dismantling the internal springs of the valves.
Advantages of rods with hydrocompensators
The UMW-4216 engine with hydrocompensators does not require additional maintenance due to the absence of valve gaps throughout the entire period of operation. Due to this, noise level is noticeably reduced. High revs The engine is no longer a critical character, since the design of the hydrocompensers laid a factor for stabilizing the appearance of critical loads. The degree of wear of the conjugate surfaces of the parts of the mechanism is significantly reduced. Due to the optimization of gas distribution phases, harmful impurities of exhaust gases are stable low entire period of operation.
Ventilation Carter
The engine is supplied with a closed crankcase cavity ventilation system. Some of the gases passing through compression rings are given to the intake manifold with a combined method. The system of the system is carried out due to the pressure difference between the crankcase and the intake path. At a time when the 4216 engine operates in high load mode, the gases are discharged through a special large branch.
On the small branch, the gas removal occurs at the time of operation of the installation on and with minimal loads.
In the front cover of the pusher block, the ventilation system is installed, which performs the function of separating the microparticles of oil from gases and serves to prevent dust from entering the dust at the moment of increasing the thrust in the inlet system.
Butter
Engine lubrication system - combined type (spraying and under pressure). The oil that sucks the oil pump from the pallet passes through the oil channels into the oil filter housing. It then enters the cavity of the second jumper of the unit, and from there - to the highway. On the root crankshafts and camshaft, the oil comes from the oil highway.
Running cakes are lubricated by the receipt of oil across the channels from such a principle, the details of the gas distribution mechanism are lubricated.
The volume of poured oil into the engine crankcase is 5.8 liters.
Cooling system
Cooling system closed, water. It consists of a water pump (pump), a thermostat, a water shirt in the cylinder block and a head, a cooling radiator, a tank expander, a fan of forced cooling, connecting pipes and a radiator of the salon heater.
Engine "Gazelle" 4216, depending on the modification may have distinctive features By the method of connecting the expansion tank and heater radiator.
At this time, the engine cost will vary depending on the year of release and from its modification. For example, the first equipment with the presence of a generator and starter, with a diaphragm type adhesion, with flat support brackets under the updated frame will cost about 130 thousand rubles.
If you purchase a 4216 engine from hand, the price will significantly decrease (depending on the car run).
So, we found out what technical characteristics of the Ulyanovsk plant UMP-4216 have technical characteristics.
Engine lubrication system (Figure 6.10) Combined. Oil pressure in the lubrication system When operating the engine on M8V X oil, oil temperature in an oil crankcase 80 ° C and a disconnected oil radiator should be at least 343 kPa at a speed of 2000 rpm of the crankshaft and at least 108 kPa at a speed of 600 / min.

Figure 6.10 - Engine Lubricant System
To control the pressure of oil on the engine, two sensors are installed. One of them is associated with an oil pressure pointer, and the other with a control lamp of an emergency oil pressure in the engine lubrication system. The emergency oil pressure sensor is triggered at a pressure of 39-78 kPa. With a minimum rotation frequency of the crankshaft on idle mode and a disconnected oil radiator control lamp Emergency oil pressure should not burn. Lamps lighting indicates a malfunction of a lubricant system that should be immediately eliminated.
In the engine lubricant system there are two valves: reduction in oil pump and bypass in the oil filter. Both valves in the operation of the adjustment do not require.
To cool the oil in the lubricant system there is an oil radiator. Include it, opening the crane, it is necessary at air temperature above 20 ° C and when driving in severe road conditions, regardless of ambient temperature.
Steel stamped lubricant. The plane of the lubricant container with the block is sealed with cork pads. Gaskets that seal the front and rear parts of the lubricant, before installing the place are abundantly moisturized with water to eliminate their breakage.
The lubricant pump (Figure 6.11) of the gear type is placed inside the lubricant container and is attached to the cover of the fourth root bearing with two studs. Pump gears straight metal ceramics. Between the housing 3 and the plate 6 of the pump installed a paronit gasket 7 with a thickness of 0.3-0.4 mm. Installation When repairing a pump, thicker gasket is unacceptable, as this will reduce the pump performance and the pressure being created by it. From entering large particles (dirt, vet, etc.) The pump is protected by a frame of 11 with a grid.
The reduction valve 13 provides the necessary oil pressure in the highway when operating the engine on any modes, and compensates for the engine wear, which increases with the wear of the engine consumption through the bearings, as the lubricating pump has redundant performance. With an increase in pressure in the lubricant system above the allowable oil presses the valve and excess oil is reset into the cavity of the lubricant pump.
The drive of the lubricant pump (Figure 6.12) is carried out from the camshaft by a pair of screw gears. The leading gear 7 is made at the same time with the distribution shaft. The driven gear 8 is fixed with a pint on a roller rotating in a cast-iron case 2. The upper end of the roller has a slot disconnected by 0.8 mm in one direction, which includes the shank of the ignition distributor of the ignition sensor.
Between the drive roller and the pump roller there is an intermediate plate 10 connected to them hinged. This ensures some freedom to install the pump. But to reduce wear in hinged drive connections and to ensure its impeccable operation, it is necessary to install a pump as soon as possible with a drive hole.

Oil cleaning filter (Figure 6.13) Four-change, collapsible design, located on the block on the right side of the engine (it is possible to install an oil filter VAZ-2101 of an unblocked design). The filter element 3 is located in the filter housing, through which all the oil passes from the engine parts. If the filter element is strongly contaminated or the viscosity of the oil (with low temperatures The surrounding air), then the bypass valve 11 will miss the oil main oil into the oil highway. The bypass valve is designed for pressure drop 58-73 kPa.

At the entrance B. oil filter The check valve 5 is located, which opens under a 3-7 kPa pressure generated by the oil pump. When stopping the engine, it closes and does not allow oil from the body, thereby protects the short-term "oil starvation" of the engine at the next start of the engine.
The oil radiator is set before the waters of the water radiator and is attached to the sidewalls of the blinds. Oil fence in the radiator is carried out from the oil line. The position of the crane handle along the hose corresponds to the open position of the crane, and across the closed.
Engine crankcase ventilation system. The engine has a closed ventilation system (Figure 6.14), which is a combined crankcase ventilation with two pipelines 1 and 2. Pipeline 1 connects the engine crankcase with a mixing chamber of the carburetor through a fluid feeder with a diameter of 2 mm, located below the throttle axis. SPAC of gases on it goes when the engine is running on low loads of the idle mode. On the other engine operation modes, most gases are discharged through the pipeline 2. To separate the droplets of oil (suspended state in crankcase), an oil separator is installed in the front cover of the pusher box.

- change oil.
Common breakdowns
The most common malfunction of the engine UMW-4216 includes:
Engine UMW-4216
- Oil leakage. It occurs due to a loose fit of the crankshaft seal, due to the exceedment of the recommended number of revolutions - 2500.
- Hanging at idle, Motor "Troit". Factory defect.
- Tapping in the motor. Perhaps after every 15 thousand km run. The culprits are unregulated valves or problems with the crankshaft.
- Strong vibration. Problems in the work of the crank-connecting mechanism or the ignition system.
- Motor overheating. It occurs due to the failure of the thermostat, pump or gasket extension.
Tuning options
For this motor Only one version of the tuning, optimizing the "urban" regime, is advisable. To do this, carefully adjust the valves, "bring to mind" the head of the BC and upgrade the combustion chambers.

This engine is the only one among russian enginesThe installation on which gas equipment does not lead to loss of warranty.
Motor lubrication system UMP-4216 combined: under pressure and splashing. Through the oil treatment, the oil is suused with an oil pump and through a full-flowered oil filter is supplied to the oil highway.
On the oil pump, a reducing valve is installed with a reworking oil into a highway bypassing the filter element when it is high resistance (clogging, a cold engine start). The bypass valve opens when the pressure difference at the inlet and outlet from the filter 58-73 kPa (0.60-0.75 kgf / cm2). At ambient temperature above, plus 5 degrees need to open an oil radiator crane. The crane is open when his lever is directed along the hose.
Before the crane of the oil radiator, a limiting valve is installed, which opens the oil access to the radiator only at a pressure of more than 70-90 kPa (0.7-0.9 kgf / cm2). All lubrication valves are adjusted at the factory and regulate them in operation is prohibited.

Pressure in the engine lubrication system UMP-4216.
Pressure in the engine lubrication system UMP-4216 at an oil temperature plus 80 degrees with a disconnected oil radiator should not be less than 125 kPa (1.3 kgf / cm2) at a speed of rotation of the crankshaft 700 revolutions per minute and 245 kPa (2.5 kgf / cm2) at 2000 revolutions per minute. During the operation of the car, it is necessary to follow the operation of oil pressure sensors. An emergency oil pressure sensor is triggered at a pressure of 39-78 kPa (0.4-0.8 kgf / cm2).
It is forbidden to operate the car with a burning lightning lamp of an emergency oil pressure. On the warm engine UMP-4216, with a good lubrication system in idling mode and with a sharp braking, the warning lamp may be lit, but must immediately go out with increasing the rotation frequency of the crankshaft.
Maintenance of the Motor Lubrication System UMW-4216, used motor oils.
Check the oil level in the UMW-4216 engine crankcase is necessary before departure and every 300-500 mileage kilometers depending on the engine status. The oil level should be between marks P and 0 oil level pointer. The volume of oil is fused into the engine crankcase from the tag 0 to the tag P, is approximately 2 liters. The oil level is measured 2-3 minutes after stopping the heated engine.
In the Carter of the UMW-4216 engine, it is necessary to fill in the characteristics not lower than B3 / D1 a hundred AAI 003 or SF / CC via an APJ classifier. Classes sAE viscosity 15W-30, SAE 15W-40 All-season, SAE 20W-40 - for areas with a hot climate, SAE 5W-30, SAE 10W-30 - for areas with a cold climate. The exhaust oil is to drain from the engine crankcase immediately after the trip until it is hot. In this case, the oil merges quickly and completely.
The first oils must be made after running the engine, after 2,000 mileage kilometers with simultaneous replacement of the oil filter. Subsequent oil replacements are carried out every 10,000 kilometers of the car's mileage with a simultaneous replacement of the oil filter. It is recommended to flush the engine lubrication system through two oil shifts.
To wash the lubrication system, it is necessary to drain the hot engine from the hot engine crankcase, pour a special detergent oil by 3-5 mm above the tag 0 on the oil level index and give the engine to work for 10 minutes. Then deteriorating oil to merge, replace the replaceable oil filter and pour fresh oil. Mixing residue is allowed detergent After plum S. fresh oil. In the absence of detergent oil, the flushing can be made of clean engine oil.
