Design
Four-stroke engine with a complex microprocessor fuel injection control system and ignition, with multipoint phased fuel injection, with inline cylinders and pistons rotating one common crankshaft, with the lower arrangement of the camshaft, with a customized exhaust gas release system. The engine has a liquid cooling system of a closed type with forced circulation. Combined lubrication system: under pressure and splashing.
Cylinder block
The main constructive difference between the engines is that they have an aluminum block with flooded thin-walled sleeves from a special wear-resistant cast iron (ICH-33M). Between the cylinders there are ducts for coolant. The sleeve is a thin-walled casting made by centrifugal casting. The minimum diameter of the outer surface of the sleeve (based on the base of the booths) after machining is 106 ± 0.2 mm.
The crankshaft seal cover is cast from aluminum alloy and attached to the bottom of the block with two studs with a diameter of 8 mm. After mechanical processing of the working surface of the sleeves (boring and honing), the sleeves are broken down by diameter by five dimensional groups (A, B, B, G, D). The marking of the dimensional group designation for each sleeve is applied to the lateral surface of the water shirt located inside the cavities of the pushers boxes.
Crankshaft
The crankshaft is cast from high-strength cast iron HCH50, has five supports, assembled with flywheel and clutch is dynamically balanced: permissible imbalance of no more than 35 g cm.
Shatun.
Rolling rods - steel (steel 45g2) forged with a core of a foreign cross section. In the piston head of the rod, a thin-walled sleeve of tin bronze is pressed. The crank head rod is detachable. The cover of the crank head is attached to the rod with two bolts with a grinding plant.

To ensure the required gap, the pistons are separated (by diameter) to five groups indicated by the corresponding letter, which is knocked on the bottom of the piston. Piston Fold Floating Type, the outer diameter of the finger is 25 mm, internal - 14 mm. The whole finger is 148g.
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.

Figure 6.13 - Oil filter
At the inlet in the oil filter is a check valve 5, which opens under a pressure of 3-7 kPa, created 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.
1 and 2 - pipelines; 3 - oil separator
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.
In 1997, the Motor Plant in Ulyanovsk began assembling engines of high power. The first sample was the carburetor UMP 4215, and a year later, the engineers created the engine 4216, equipped with an injector fuel supply and subfolding under the Euro 2. Serial release began in 2003, and a modification was released to the market basic modification 42164 and varieties that meet the requirements of Euro 4.

Typical malfunctions
The UMZ plant declares the resource of the 4216 line engines in 250 thousand to the need for overhaul. In practice, malfunctions are manifested earlier.
The main problems with which you have to face the owners of commercial cars with engine UMP From the series under consideration:
- high flow Oils on a volunteer through piston rings;
- leakage of oil;
- shup of engine valves;
- refusal of electronic sensors;
- engine overheating for various reasons.
Premature breakdowns usually lead:
- violation of the rules of operation - the driver is overly "twist" the engine and overloads it, or exceeds the maximum allowable loading of the machine;
- riding under heavy conditions;
- incorrect, unqualified or late maintenance;
- the use of bad fuel, lubricant or cooler.
Marriage in the 4216 series is relatively rare, so the fault is most often connected with the actual breakdown, and not factory flawlessness, although there are such cases.
Other possible problems:
- The engine "zaplivit" with oil, the liquid appears on the details.
Possible cause - the wear of the rear seal of the crankshaft. The problem is often manifested with a long ride for revolutions of more than 2500, 4216th is not designed to work on very high revolutions. Replacing the surpasses problem completely eliminates.
- Engine vibrations, the engine "pulls" idling or in motion.
The problem arises due to unevenness combustible mixture in cylinders. Its reasons may be faults in the ignition system (candles, coils, etc.) or injection (for example, clogged nozzle). The car consumes a lot of fuel, on dashboard CHECK light can light up, and an ignition skip error is written to the computer. In this case, a comprehensive diagnosis is required.
- Engine knocks.
Most often, the causes are becoming inclined valves. To solve the problem, adjustment should be carried out. This procedure applies to regular and normally, every 15 thousand runs should be carried out. In addition to the valves, the problem can be partially solved by installing hydrocompensators.
If the valves are in order, check the status of connecting rod liners and camshafts.
- Engine vibration.
Typically, the motor begins to vibrate due to problems with ignition or physical wear of pillows. It is also possible to unbalance the crank-connecting mechanism.
- Engine overheating.
Possible reasons for the fact that the engine began to warm up - breakage of the pump or thermostat, or education air traffic jam in the cooling system.
Ignition problems and fuel supply systems
These malfunctions are considered characteristic of engines with the 4216 injector.
- The car is not included in self-diagnostic mode.
The reason is the failures in the ECU or diagnostic.
- After activation of the ignition does not go out Check.
Possible causes - a failure of the ECU, control circuits or control system as a whole.
- The gas station does not start after turning the ignition key.
Probable reason - the output of the pump failure, problems with the ECU, power circuits, or pump relay.
- Starter "does not twist" the engine.
Perhaps the battery is discharged, the throttle or starter itself, or there is a breakdown in the control / feeding chains of the starter.
- The engine is started not from the first time, the turns are floating, the motor stalls, from the exhaust goes smoke in black.
The reason is the malfunction of the synchronization sensor or an increase in the gap between the synchrocheter and the crankshaft synchronization disk.
- The engine does not start "on the hot", the temperature sensor shows the temperature of the coolant higher than 70 degrees.
Possible problems - no fuel pressure in the highway, the pressure is too low or, on the contrary, high, failed RXX, the crankshaft sensor, the control unit, or when installed, confused the coil control circuits.
You must carefully check all these nodes. Thus, the pressure of the fuel may be precipitated by the banal cause of an empty tank or air traffic jam in the highway. Low pressure occurs when the fuel channels and the filter are clogged, the appearance of the supply in the inlet path, faulty regulator Pressure of gasoline or leakage of benzins. Too high pressure can appear due to a broken pressure regulator, clogged plum pipe or benzone pump breakage.
- Crankshaft in idle mode rotates too fast.
The reasons: throttle valve It is closed until the end, the temperature sensor was fucked, the RXH channel is not closed.
- Failures in the work of the cylinder, or a complete refusal of such.
Causes: Armor or tip malfunction, Candle clearance disruption, Nagar on it, or full breakdown of spark plugs, nutritional / nozzle control problems, clogging or breakage of the latter. Occasionally a malfunction arises due to the failure of the ECU.
- Feed / cease to work two cylinders immediately.
Possible causes: Malfunction of ignition coils (or their feeding and control systems), ECU failure.
- Unstable work at idle.
Probable faults leading to this: Subsiduction on the inlet, in the ventilation of the engine crankcase or brake system, getting water to the tank, the rattles of contacts of DPDZ.
- Sleepy during acceleration.
The error occurs due to problems with the ignition or the rattling of contacts of DPDZ.
- The engine cannot reach the maximum power.
Causes: The throttle of the throttle opens not to the end, clogged fuel filter, Rassed DPDZ, polluted air filter, Sensor broke absolute pressure Or will fail the high-voltage engine chains.
- Abnormally high fuel consumption, CO emission.
Leading to this problems: the failure of the absolute pressure sensor, the depressurization of the nozzles, air supply, too high pressure in the fuel line (see above).
- Abnormally high emission ch.
As a rule, it arises due to faulty high-voltage chains.
- Motor detonation.
It is possible to flood low-quality gasoline (with a disturbed ratio of fractions, a low octane number, or diluted with water). Also, the problem can be wounded in impaired shielding of detonation sensor cables, cracking of the sensor or the failure of the ECU.
Caparent
In the case of 4216 overhaul It becomes necessary if:
- knocking the crankshaft (it means it reached a critical degree of wear);
- bC sleeves are worn out;
- after replacing the oil pump, the pressure remains low.
All this is the indicators to the full bulkhead, engine defecting and replace damaged parts.
