Currently popular and common commercial vehicles of the GAZ brand are equipped with UMZ engines produced at the Ulyanovsk Motor Plant.

A bit of history

The Ulyanovsk Motor Plant dates back to 1944, and only in 1969 the company produced the first UMP engine. Until the sixty-ninth year, the plant was engaged in the production of small-capacity UMZ-451 engines and their components.

Since the release of the first motor, they have faithfully served on trucks, off-road vehicles, on small buses. In 1997, AvtoGAZ became the main consumer of engines, which equipped most models of the GAZelle line with UMP units.

Design features

At the moment, there is a wide range of internal combustion engines of the UMP model range, which are installed on different models of Sobol, UAZ, GAZelle cars. Installed engines have a number of common features, but may differ in some details and principles of operation:

• Carburetor and injection.
• Four-cylinder in-line.
• Power 89-120 hp s.
• Environmental standards Euro-0, Euro-3, Euro-4.

All engines are light, small and reliable. They are distinguished by an affordable price.

One of the features of the engine is the original design of the cylinder block, cast from aluminum, with pressed-in liners made of gray cast iron. Crankshafts of motors of all modifications are hardened during manufacture of the main and connecting rod journals with high-frequency currents. A self-locking rubber seal seals the rear of the crankshaft.

Modifications of the lineup

UMP motors have two lines of power units designed to equip various vehicles.

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

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

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

This review is dedicated to the UMZ-4216 power plant, its characteristics and properties will be detailed.

Pros

The advantages of the motor rightfully include maximum torque at low speeds, excellent technical characteristics, as well as ease of maintenance of components and assemblies. The 4216 engine became the first domestic device that has a warranty period when a gas engine is installed on it.equipment.

Modernization

The unit is equipped with a microprocessor control system for fuel mixture injection and ignition system. The knock and oxygen sensors of the 4216 engine directly affect the operation of the integrated electronic control system and the unit as a whole. To change the economic characteristics and increase competitiveness, the following design additions were made to the power plant:

• Cylinder compression has been increased to improve performance.
• To reduce oil consumption, the crankcase exhaust system has been upgraded.
• The reliability of the motor is ensured through the use of advanced parts and materials.

At the same time, the unit has not changed in terms of overall parameters and standard characteristics (working volume - 2.89 l, piston stroke, cylinder size).

For the first time, the GAZ-4216 engine began to be equipped with imported parts, which only increased the quality of work and durability in operation. The power unit was equipped with spark plugs and fuel injectors manufactured by Siemens, as well as a German-made Bosch throttle position sensor.

Main UMP malfunctions

Previously, the most common engine failure was damage to the intake manifold. According to the developers, a manifold made of fragile material was installed on the 4216 engine. But already in 2010, this shortcoming was corrected by the use of better material.

In the systemcooling was also found to be flawed.

At medium engine speeds and when the car was moving at a speed of 60 km / h, the temperature of the coolant was normal, but as soon as the speed was slowed down or got into a traffic jam, the 4216 engine rapidly gained temperature, until the coolant boiled. The reason lay in the electromagnetic clutch, which turned on the forced cooling fan.

Technical parameters

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

A GAZelle with an UMZ-4216 engine can reach a maximum speed of 140 kilometers per hour, which is a good indicator for this class of car. Fuel consumption depends on the workload of the car, 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 l.

Power system

Consists of a fuel supply device and various fuel lines, injectors, fuel and air filters, air supply pipes and a receiver, an idle speed regulator.

Feed controlfuel is provided by a variety of sensors: charge air temperature element, crankshaft and camshaft position sensors, absolute pressure detail, throttle position.

The supply control system is also equipped with an oxygen indicator. The latter is installed in the exhaust system in front of the converter. For greater reliability and durability, the 4216 engine (injector) should only run on high-quality gasoline, taking into account regular replacement of fuel filters and periodic diagnostics of fuel equipment. Motorists say that with proper operation, the total resource of the power unit can reach 500 thousand kilometers. The injection units of the Zavolzhsky Motor Plant also differ in this feature (meaning the ZMZ 405 and 406 engines).

Timing mechanism

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

The valve springs did not change, and this led to the fact that the acting force on the springs crossed the norm, and now it was equal to 180 kgf. When installing a conventional rod set on a new engine before a warm engine condition is reachedtapped hydraulic lifters.

To prevent this problem, change the spring force by removing the internal valve springs.

Advantages of booms with hydraulic lifters

The UMZ-4216 engine with hydraulic compensators does not require additional maintenance due to the absence of valve clearances throughout the entire period of operation. This significantly reduces the noise level. High engine speeds are no longer critical, since the design of hydraulic compensators includes a factor for stabilizing the appearance of critical loads. The degree of wear of the mating surfaces of the mechanism parts is significantly reduced. Due to the optimization of the gas distribution phases, harmful impurities in the exhaust gases are consistently low throughout the entire period of operation.

Crankcase ventilation

The motor is equipped with a closed-type crankcase ventilation system. Part of the gases passing through the compression rings is discharged into the intake manifold in a combined way. The operation of the system is carried out due to the pressure difference between the crankcase and the intake tract. At the moment when the 4216 engine is operating in the mode of increased loads, gases are removed through a special large branch.

The gas is removed from the small branch when the unit is running at idle and at minimum loads.

A draft regulator of the ventilation system is installed in the front cover of the pusher block, which performs the function of separating oil microparticles from gases and serves toprevent dust from entering the crankcase at the time of increasing thrust in the intake system.

Butter

Engine lubrication system - combined type (splash and pressure). The oil that the oil pump draws from the sump passes through the oil passages into the oil filter housing. Then it enters the cavity of the second jumper of the block, and from there - into the highway. The crankshaft and camshaft main journals receive oil from the oil line.

The connecting rod journals are lubricated by the flow of oil through the channels from the main bearings. According to this principle, the parts of the gas distribution mechanism are lubricated.

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

Cooling system

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

The GAZelle 4216 engine, depending on the modification, may have distinctive features in the way the expansion tank and heater radiator are connected.

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

If you buy a 4216 engine from your hands, the price will drop significantly (depending on the mileage of the car).

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