The engine is 4216. UMP-4216. Specifications

Now popular and common commercial vehicles of GAZ brand are equipped with UMZ engines manufactured at Ulyanovsk Motor Plant.

A bit of history

The Ulyanovsk Motor Plant has begun its business from the distant 1944, and only in 1969 the enterprise produced the first UMZ engine. Until the sixty-ninth year the plant was engaged in the production of small-displacement engines UMZ-451 and their components. Since the release of the first motor, they have faithfully and faithfully served in trucks, cars with increased terrain, on small buses. In 1997, the main consumer of engines was AvtoGAZ, which completed the UMZ units with most models of the GAZel line.

Structural features

At the moment, there is a wide range of ICEs for the UMZ lineup, which are installed on different models of Sobol, UAZ and GAZel cars. Installed engines have a number of common features, but they may differ in some details and principles of operation:

• Carburettor and injector.
• Four-cylinder with in-line arrangement.
• The power of 89-120 liters. from.
• Ecological standards "Euro-0", "Euro-3", "Euro-4".

All engines are light, compact and reliable. They are distinguished by the affordable cost.

One of the features of the engine can be called the original design of the cylinder block, cast from aluminum, with pressed sleeves made of gray cast iron. The crankshafts of motors of all modifications during manufacture pass hardening of the root and connecting-rod necks with high frequency currents. A self-calibrated rubber seal seals the rear of the crankshaft.

Modifications of the model range

UMP engines have two power unit lines designed to equip different vehicles.

Cars of the GAZel family are equipped with the following models: UMZ-4215; UMP-4216; UMP-42161; UMP-42164 "Euro-4"; UMP-421647 "Euro-4"; UMP-42167.

The main part of the engines comes out in several variations, which differ in their configuration, power and economy. At the moment, the production of gasoline-powered units with an octane rating of 80 has ceased.

All engines are designed for 92 and 95 gasoline, as well as the ability to work on gas.

This review is devoted to the UMZ-4216 power plant, its characteristics and properties will be described in detail.

pros

The advantages of the motor include the right maximum torque at reduced speed, excellent technical characteristics, as well as ease of maintenance of units and units. 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-controlled fuel injection and ignition system. Detonation and oxygen sensors of the engine 4216 directly affect the operation of the complex electronic control system and the unit as a whole. To change economic characteristics and increase competitiveness, the following constructive additions were made to the power plant:

• To improve performance, the compression ratio in the cylinders was increased.
• To reduce oil consumption, modernized the system for tapping crankcase gases.
• The reliability of the motor is ensured by the use of improved parts and materials.

At the same time, the unit did not change in terms of overall dimensions and standard characteristics (working volume - 2.89 liters, stroke of pistons, cylinder size).

For the first time the GAZ-4216 engine was equipped with parts of imported production, which only increased the quality of work and durability in operation. The power unit was equipped with fuseplugs and fuel injectors produced by Siemens, as well as a Bosch throttle position sensor.

The main faults of UMZ

Previously, the most frequent engine failure was damage to the intake manifold. As claimed by the developers, the engine 4216 was installed collector, made of a fragile material. But already in 2010 this defect was corrected due to the use of a better material.

In the cooling system, too, a flaw was detected. At medium engine speeds and when the car was moving at a speed of 60 km / h, the coolant temperature was normal, but if you just slowed down or got caught in a traffic jam, the 4216 engine quickly picked up the temperature, right up to the boiling point of the coolant. The reason was covered in an electromagnetic clutch, which included a forced cooling fan.

Technical specifications

The engine runs on AI gasoline with an octane rating of 92 and 95. Four-cylinder, with a row-positioned cylinder, eight-valve. Cylinders have the following working order - 1243. Its diameter is one hundred millimeters, and the displacement of the piston is 92 millimeters. The engine capacity is 2.89 liters, it develops the power of 123 "horses" at four thousand revolutions. The compression ratio of the motor is 8.8. The maximum torque is 235.7 at 2000-2500 rpm.

"GAZelle" with the UMZ-4216 engine can develop a maximum speed of 140 kilometers per hour, which for this class of cars is a good indicator. The fuel consumption depends on the car's load, driving style and road conditions, but in general it looks like this: at a speed of 90 kilometers per hour - 10.4 liters. When driving at a speed of 120 km / h - 14.9 liters.

Supply system

It consists of the fuel supply device and various fuel lines, injectors, fuel and air filters, air supply and receiver connections, idle speed regulator.

The fuel supply is controlled by a variety of sensors: the temperature element of the injected air, the crankshaft and camshaft position sensors, the absolute pressure part, the throttle valve position. The feed control system is also equipped with an oxygen indicator. The latter is installed in the 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 of fuel equipment. Motorists say that with competent operation the total life of the power unit can reach 500 thousand kilometers. This feature is also different for the injection plant of the Zavolzhsky motor plant (the engines of ZMZ 405 and 406 are meant).

Gas distribution mechanism

In 2010, at the Ulyanovsk plant, the gasoline engine underwent a process of modernization of the gas distribution mechanism. In general, it affected the change in cam profile camshaft, which contributed to an increase in the valve stroke by one millimeter. These innovations were necessary to improve the stable operation of the unit at idle, and also to achieve the norms and requirements of the Euro-3 standard.

The valve springs did not change at the same time, and this led to the fact that the acting force on the springs crossed the norm, and now it was 180 kgf. When installing a regular set of rods on a new engine, until the state of the heated engine was reached, the knocking of the hydraulic compensators was heard.

In order to prevent this problem, the force of the springs should be changed by removing the internal springs of the valves.

Advantages of rods with hydraulic compensators

The UMZ-4216 engine with hydraulic compensators does not require additional maintenance due to the absence of valve gaps during the entire period of operation. Due to this, the noise level is noticeably reduced. High engine speed is now not critical, since the construction of the hydraulic compensators is based on the stabilization factor for the appearance of critical loads. The degree of wear of the mating surfaces of the parts of the mechanism is significantly reduced. Due to the optimization of the gas distribution phases, the harmful impurities of the exhaust gases are stably low throughout the entire operation period.

Crankcase ventilation

The motor is supplied with a ventilation system of the crankcase cavity of the closed type. Part of the gases passing through the compression rings is diverted to the intake manifold in a combined way. The system is operated by a pressure difference between the crankcase and the intake path. At the moment when the engine 4216 is operating under increased load conditions, gases are discharged through a special large branch.

On a small branch, the gas is removed when the unit is idling and at minimum loads.

In the front cover of the pusher unit is installed a regulator of the draft of the ventilation system, which performs the function of separating the microparticles of the oil from the gases and serves to prevent dust from entering into the crankcase when the draft in the intake system is increased.

Butter

The engine lubrication system is of a combined type (spraying and under pressure). The oil that sucks the oil pump out of the pallet passes through the oil channels into the oil filter housing. Then it enters the cavity of the second jumper block, and from there - into the trunk. On the crankshaft and crankshaft, the oil comes from the oil main.

Crankpins are lubricated by oil flow through the channels from the main bearings. This principle lubricates the parts of the gas distribution mechanism.

The volume of oil poured into the crankcase of the engine is 5.8 liters.

Cooling system

The cooling system is closed, water. It consists of a water pump (pump), a thermostat, a water jacket in the cylinder block and a head, a cooling radiator, an expansion tank, a forced cooling fan, connecting pipes and a heater radiator.

The engine "GAZelle" 4216, depending on the modification, can have distinctive features by the way of connecting the expansion tank and the radiator of the heater.

At this time, the cost of the engine will vary depending on the year of manufacture and on its modification. For example, the first complete set with the presence of a generator and a starter, with a diaphragm-type clutch, with flat support brackets for an updated frame will cost about 130 thousand rubles.

If you buy a 4216 engine, the price will decrease significantly (depending on the mileage of the car).

So, we found out what the Ulyanovsk plant UMZ-4216 has technical characteristics.
