22.10.2019

Distinguishing from them more power and better dynamics with a smaller working volume (2.3 liters vs 2.5 in 402), moreover, new engines turned out to be more economical. In the first years of release, carburetor motors were installed on the car.

Engine ZMZ 406 for cars Gas

On VOLGA and Gazelle cars used:

4061.10 - carburetor on 76 gasoline (compression ratio - 8);
4062.10 - injector at 92 gasoline (compression ratio - 9.3);
4063.10 - 92 gasoline carburetor (compression ratio - 9.3).

On some machines, the gas was used by other engines of the Savolzhsky motor factory, for example, ZMZ-405.
Since 2006, only injection motors, more modern and better characteristics, were installed on Cars Gazelle and Volga. Disadvantages inherent in carburetor options remained in the past.

ZMZ-406 is a row four-cylinder engine. Its main part is a block of cylinders made of gray cast iron.

Disassembled Motor ZMZ 406

It is heavier than aluminum, but has increased rigidity and does not require replaceable sleeves.
The engine design has changed significantly compared to the previous model (ZMZ-402). An important feature - two camshafts are located in the GBC, one of which is intended for intake valves, the other for graduation. The drive of their chain, two-stage, with hydraulic tensioners operating in automatic mode.

Each cylinder has four valves to improve the intake of the working mixture and exhaust gases. Valves are powered by hydrotherapiles and do not require adjustment of gaps. Spark plugs are located in the center of the combustion chambers, which made it possible to increase the degree of compression.

The volume of coolant, liters - 10.5.

Comparison of injection and carburetor engines

The main difference between these modifications in the method of preparation and inlet of the combustible mixture into the combustion chamber.

Carburetor for engine ZMZ 406

A traditional method is used on the carburetor 4061 and 4063, the injector 4062 applies a new (for that time) the injection option of gasoline through the nozzles controlled by an electron microprocessor.
When using injectors, the accuracy of the dosage of fuel, injection and arson takes place at an optimal moment increases. The engine performance increases, the power and torque increases, which is clearly visible when comparing the characteristics of injection and carburetor engines (see above).

Ready for installation Injector Motor ZMZ 406

Besides better characteristicsThe injection motors are more economical and malicious damage to ecology. This is due to the more complete fuel combustion under the control of an electronic unit that does not need regular maintenance.

W. carburetor engines There are advantages. This is a simplicity of design, the ability to adjust and repair without the involvement of specialists. True, it can turn into a disadvantage: with incorrect adjustment of the carburetor, various negative phenomena occur, for example, unstable rapids at idle. If you are not sure about your abilities, it is better to contact the workshop.

Features of the injector power system

It is one of the main engine, the adjustment does not require, but it is still necessary to monitor its condition. Nozzles and pressure regulator work normally only on pure gasoline. Place on proven gas stations, sometimes (better than autumn) drain sucks and water from the tank. When inclined on benzins in places of connectors, it is necessary to seal them (tighten the fitting without excessive effort or replace seals).

The cracked hoses should be replaced to avoid breaking. But note that fuel in highways for fuel pump is under high pressure (About three atmospheres), when separating the elements of the system, it must be reset.

To do this, turn off the gas station (the easiest way to remove the appropriate fuse), start the engine and wait: it will produce fuel in the system and stalls.

Run the starter (do not press the gas pedal) for a few seconds. Remove the negative battery terminal to avoid accidental spark. Now you can disconnect the desired items.
After performing the work, do not forget to put the fuse of the gas station and the terminal. Turn on the ignition and wait a few seconds, pumps the fuel into the system. Get the engine and check if there are leaks.

Defining a malfunction in the engine control system

This system comes in information from various sensors mounted on the engine, the normal operation of the power and ignition nodes depends on it. There is an opinion that it is possible to determine the malfunction in this system only in technical Center With the help of special devices. It is not quite true, you can find a problem on your own.

On the appearance of a problem is noting alarm " Check Engine»On the instrument panel, burning continuously. Each malfunction has its own code that the system writes into memory, the task is to obtain it and determine the cause according to the special table.

To find out the code, find the diagnostic connector located in motor compartment on right. Remove the cover from it and closer the copper wires 10 and 12. Now the control unit is in the issuance of information. Sit to the driver's seat and turn on the ignition, you will see the outbreaks of the alarm. Your task is to count them.
The fault code consists of two or three digits. The number of signalkor flashes is equal to the digit, then pause and the next digit.

For example, the fault code 26 will be shown like this:

2 short flashes, each lasts 0.5 seconds;
Pause with a length of 1.5 seconds, which means the transition to the next digit;
6 short flashes;
Long pause about 4 seconds, meaning the end of the code.

The control unit begins to transmit information from code 12 repeating three times. This shows the serviceability of the diagnostic system. Then the malfunction code, it also repeats three times; Then - the transition to the next problem, if it is. After listing all the codes in memory, the block will repeat all the information until you take the jumper from the connector. So you can not rush and check again.

After determining the malfunction code, look at the table (it can be printed and carry it in the glove compartment). You will immediately see what it is not working. If the memory is empty, only code 12 is transmitted.

SCM 406 Motor Device Scheme

It should be noted that the failure of one of the sensors will not lead to the engine stop (except for the angular position sensor crankshaft, whose refusal is very unlikely). If a malfunction occurs, the computer goes to the emergency program, the engine works worse, but you can get to the workshop.

ZMZ 402 and its enhanced injector version of the model 405.

It is strange that this installation is marked with a great value than its heir. The inexperienced motorist will think that the ZMZ 406 is designed much later than the 405th and is more productive. Well, let's look at what the 406th engine is different.

a brief description of

This engine refers to a number of 4-cylinder carburetor gasoline installations. ZMZ 406 has an inline layout of cylinders. Quantity in GBC - 2. Operation of the cylinders: 1-2-4-2. The operating volume of the engine is 2.3 liters, power - 130 horsepower.

Device

Based on Figure No. 2, we see that the engine ZMZ 406 consists of:

Carter pallet.
Masloballcher.
Oil pump.
Pump drive roller.
Crankshaft.
Rod.
The driven gear of the oil pump drive.
Covers of the same device.
The drive gear of the oil pump drive.
Pistons.
Pasters
Exhaust valve.
The inlet pipeline with the receiver.
Camshaft inlet valve.
Hydraulic pusher.
The camshaft of the exhaust valve.
Covers CHC.
Oil level pointer.
Graduation manifold.
Exhaust valve.
Cylinder block.
Cork plug holes.

Note: The numbering of the parts of the ZMZ 406 engine coincides with the designation of the devices in Figure 2.

As for the development, this unit was constructed in conjunction with the German company Mercedes, due to which engineers managed to increase the intersavice interval to 15 thousand and significantly improve the service life of the main parts of the engine. As practice shows, ZMZ 406 can serve up to 300-400 thousand kilometers without any boring blocks and replacing cylindrophone groups. However, this value is largely depends on the state of the chain. If it comes into a malfunction, the entire motor will fail. Hence such a disagreement: one engine can serve as 400 thousand without problems, and others break through hundreds. But it was definitely a positively involved in the reliability of this unit for the reliability of this unit, because compared to the 402nd motor, its resource of operation was almost twice.

ZMZ 406 - the thing is very serious, because the process of boring parts becomes more complicated by the 16th valves. Therefore, due to the complicated design, the price of overhaul of this motor is from 1 to 2 thousand dollars. However, at the same time, you should not forget that 16 valves provide excellent dynamics of the machine and serve where much longer than 402nd.

In conclusion, I would like to say one thing: the Zavolzhsky 406th engine really passed the stage of evolution and became an example for the imitation of many Russian automakers. His amazingly large operating resource and excellent power characteristics brought the Gorky and Volga plants one step closer to modern times. And even compared to American "Cminuse", which are staffed on a par with ZMZ, all "Gazelles" and "Volga", it does not lose its popularity, and the demand for it is growing.

The power unit of the ZMZ-406 family is gas engine internal combustionwhich is produced by Zavolzhsky Motor Plant OJSC. Development began in 1992, and the motor was carried out in the 1997 engine. For the first time, the fuel injection system was applied.

The ZMZ-406 engine was widespread and was installed on the Gorky Plant vehicles (GAZ-3102, 31029, 3110 and model Row The Gazelle family).

The Flag of Family became the Motor ZMZ-4062.10 with a 2.28 liter volume and a capacity of 150 "horses".

Power plant ZMZ-4062.10 is designed for configuration passenger cars and minibuses. And Motors ZMZ-4061.10 and ZMZ-4063.10 - for configuration trucks Small load capacity.

Engine description

Pre-motor was designed for newcomer nutrition and ignition systems that were controlled by a microprocessor.

This engine was first equipped with four valves for each cylinder, with dual chain drivers and two camshafts. Also installed electronic fuel supply system and electronic ignition.

Four cylinders have an inline location, cooling water shirt and fuel controlled injection.

The procedure for working pistons: 1-3-4-2.

ZMZ-406 The injector works on gasoline A-92. Previously, the carburetor version of the engine 4061, which worked for seventy sixth gasoline. She had restrictions in terms of release.

The unit is unpretentious in service. It has a high degree of reliability. Later on its base, the installations of the ZMZ-405 and 409 were developed, as well as a diesel version of the motor with the ZMZ-514 marking.

The lack of engine can be attributed to the bulky of the drive of the gas distribution mechanism, which is explained by its low quality Performances and a number of technological flaws.

Specifications ZMZ-406

This power unit was produced from 1997 to 2008. Cylinder cylinder was made by casting from cast iron, it has an inline position of cylinders. The engine mass is 187 kilograms. Equipped with a carburetor fuel supply system or an injector. The working stroke of the piston is 86 millimeters, and the diameter of the cylinder is 92 millimeters. At the same time, the operating volume of the engine is 2286 centimeters of cubic and is able to develop power in 177 "horses" at 3500 revolutions per minute.

Carburetor Motor.

ZMZ-406 Carburetor (402th Motor) was produced since 1996 and managed to establish itself as a simple and reliable unit. This device develops power 110 horse power. The fuel consumption of the car on this engine often depends on the driving manner and operating conditions. The power supply system of the carburetor unit is quite reliable. With timely maintenance and normal operation, using high-quality lubricating material and gasoline, it can pass to 500 thousand mileage mileage without serious breakdowns. Of course, with the exception of the crankshaft boring, which is necessary for this aggregate every 250 thousand kilometers.

Ignition system

On the ZMZ-406 engines, the ignition is carried out by igniting the fuel mixture using the microprocessor system. For all operating modes of the engine, the electronics sets the desired flammings advance angle. It also performs the function of adjusting the workflow of the coercive economizer idle move. Due to the work of this system, the engine is distinguished by its high economic indicators, the norm of the toxicity of the exhaust gases is monitored, the moment of detonation is eliminated and the power of the power node increases. On average, the Gazelle car consumes about 8-10 liters of gasoline per 100 kilometers of the path with average loads. However, if we translate it to propane or methane, the "appetite" cars increase almost twice.

Ignition diagnostic mode

When the car ignition is turned on, the SMZ-406 motor diagnostic diagnostics system automatically enters (the ZMZ-405 carburetor is not an exception). The fact of good operation electronics signals the light sensor. It should be ground when the engine starts.

In the event that the diode continues to glow, this indicates a malfunction of the elements and parts of the electronic ignition system. In this case, the breakdown should be immediately eliminated.

Injector Motor.

By technical characteristics and integral parts engine with injector system Nutrition is not particularly different from the carburetor analogue of the 405th model.

With due operation, this unit is no less reliable and practically rather than with a carburetor, and in addition he has its advantages:

Stable idling.
Low level harmful emissions in atmosphere.
The utility coefficient ZMZ-406 The injector is significantly higher, the nonsense with the carburetor, since fuel mixture served in a timely manner necessary quantity. Correspondingly, fuel economy is evident.
Increase fuel economy.
Does not need a long warning of the engine in winter.

The only minus injector motor It is high cost in repair and maintenance of the system.

Conduct diagnostic I. repair work It is not possible without special equipment and diagnostic stands. Therefore, to implement dIY repair Engine ZMZ-406 Injector - a fairly troublesome case. Often, when a breakdown occurs in the injection system, the motorist has to use the services of specialized fuel equipment maintenance centers, which may be expensive and take a fairly long time. In order to face this problem as close as possible, it is necessary to replace fuel filters in a timely manner and refuel the car with high-quality gasoline.

Block head

All modifications of the engines were equipped with one head, which corresponded to the requirements of "Euro 2". With the introduction of additional requirements "Euro 3", it was finalized and improved. It is not interchangeable with the previous model.

There are no idle systems in the new head, now their functions are assigned to an electronic controlled choke. The front wall of the part is equipped with holes for fastening the chain's protective casing, and on the left side there are fed to mount the intake system receiver brackets. The part has pressed inserts from cast iron and valve guide sleeves. The latter do not need periodic adjustment, since their drive is carried out using cylindrical pushers with hydrocomathers. The UMZ-406 upgraded head decreased in a 1.3 kilogram weight. By installing it on the engine, use the metal multilayer blocking of the block head.

Cylinder block

Improving ZMZ-406 engine, engineers were able to modify the crankcase and upgrade the casting process. So, it was possible to equip the block with ducts in the casting between the cylinders. Due to this, this element has become rigid, and the fastening of the head is carried out due to deeper threaded holes and elongated bolts. At the bottom of the crankcase there are samples that form crankshaft supports together with indigenous bearing caps. The lids are cast from the cast iron and are attached to the block with bolts.

Camshaft

The CMP-406 camshaft is made by low tide from cast iron with subsequent processing and hardening. Shafts are driven by chain transmission. On the engine installed two shafts, whose cam profiles have the same size.

The axial offset of the cams is one millimeter in relation to hydrotrifers. This factor contributes to the rotation of the elements of hydraulic drives with the engine running, which significantly affects the wear of the working surface of the pusher and makes it uniform.

The chain drive of the shafts has hydraulic tensioners that operate from oil pressure in the lubricating system. Details act on the chains directly through plastic shoes, which are attached on the axes. On the ZMZ-406 engines, after modernization, it began to apply instead of the sprats of an asterisk after modernization to increase practicality and durability. The latter are fixed on swivel levers. The mounting axes of stars are interchangeable with the axes of the shoes. Instead of the extension of the axis, the top chain tension shoe began to use a spacer, the mount of which to the block is carried out by bolts.

ZMZ-406 engine is equipped with drive chains distributional shafts. They are not able to replace the chains that were installed on earlier versions of motors.

Pistons

They are molded from aluminum alloy and have grooves under two rings of compression and one oil slimming. During operation, the bottom of the piston is cooled through the oil in the top head of the connecting rod.

The spherical working surface of the upper compression ring has a layer of coating chrome, which contributes to the best wretch of the ring. The second element is covered with a layer of tin. Occarbing ring - combined type, it consists of an expander and two steel disks. Fastening the piston to the connecting rod is carried out with the help of a finger recorded on two corkscrew rings.

Crankshaft

Molds from cast iron, followed by processing and hardening the surface of the necks of high frequency. Installed in the block on five native bearings.

The movement of the crankshaft, respectively, the axis is limited to corkscrew semirings, which are placed in flowing grooves of support and the lid of the third indigenous bearing. There are counterweights in the amount of eight pieces. A flywheel is fastened to the back of the shaft, in the opening of which the spacer sleeve and rolling bearing are pressed primary Vala Transmission shift boxes.

Butter

The power plant ZMZ-406 is equipped with a combined lubrication system. Under the action of pressure, the process of lubrication of piston fingers, connecting rod and indigenous crankshaft bearings, the supporting points of the camshaft, the hydraulic wheel of the valve, the intermediate shaft and the led gear of the oil pump are lubricated. All other parts and motor elements are lubricated by sprinkling oil.

The oil pump is a gear type, has one section and is activated from the intermediate shaft through the screw gears. The lubrication system is equipped with an oil radiator and a complete cleaning filter.

Ventilation of the closed crankcase, with a compulsory gases.

So we led detailed description All nodes, aggregates and engine systems. The ZMZ-406 scheme is in the photo above.

Car 3110 first appeared on russian market In 1996, he went to mass production since the beginning of 1997. Updated model It came to shift a few morally obsolete car GAZ 31029, and although externally cars 3110 and 31029 have similarities, a lot of changes occurred in the updated version.

Gas 3110 - Deep restyling 31029 or new model?

If you look at the side of the Volga 3110, it is practically no different from the model 31029. The same doors remained, the front wings have not changed, and the front optics have not changed. The outlines of the hood 3110 Although others, however, without any alterations, the body item is installed on the "twenty-ninth". But on the "top ten" it became completely different rear end Body:

trunk lid;
rear lights;
rear bumper.

In the chassis and power units, more significant changes occurred:

the front brakes have now become discs, they changed long ago outdated drums on the front axle;
instead of "fourteenth" wheel disks Installed stamped R15 discs;
the ZMZ 406 engine now went into a series, on 31029 these motors were set as prototypes.

Most changes occurred in the car's intra-alone space:

fully changed the instrument panel;
between the seats, a soft comfortable armrest with a bar appeared;
more comfortable and comfortable steel all seats in the cabin;
changed the steering wheel itself with the steering column.

The "fashionable" was even a ceiling lighting ceiling - he already looked quite modern, and the lamps of daylight mounted in it.

Machine Gas 3110 is a medium-sized passenger sedan C class, with a fairly roomy salon and a capacious trunk. But the "dozen" is equipped with a metal shelf under spare wheelAnd the bracket has a lot of sizes. The regiment under the reserve suits not all car owners, as it occupies almost a third of the trunk.

Compared to 31029, on the "top ten" brakes have become much softer and more efficient due to:

applications on the front axle of disks;
installation of rear brake drums of another sample.

On the model, the gas 3110 has almost ceased to set 4-stroke gears, and only the "five suggests" came with the motor ZMZ 406. The car has a gas 3110 Volga. Specifications are as follows:

auto dimensions (length / height / width) - 4.87 / 1.42 / 1.8 m;
body type - 4-dar. sedan;
the number of passenger seats - 5 people, including the chauffeur;
developed speed (maximum) - 147 km / h;
volume luggage compartment - 500 l;
full weight, taking into account passengers and luggage load - 1.8 tons;
the cutting mass (weight of a car with refilled tanks, without cargo) - 1.4 tons;
wheel base - 2.8 m;
road clearance - 156 mm;
transmission type - 4-art. or 5-st. MCPP;
rear / front wheel track - 1.42 / 1.51 m;
radius of wheel drives - R15;
standard tire size - 205/65.

If on the first cars 3110, the ZMZ-402 and 4021 engines often met, then in the future these motors were installed on "Volga" more and less. 4-st. MCPs walked on the machines until 2000, and in the future they completely disappeared on gas 3110. At the "Volgovaya dozen" of a limited series was put diesel engine GAZ-560 (5601), designed under the license of the Austrian company Steeier. Despite the excellent technical characteristics of the diesel engine, the car owners did not use much success:

The "tenth" Volga is difficult to call a speed car, especially if 402 engine installed on the machine. According to the technical characteristics of GAZ-3110 with the ZMZ-402 engine, the speed is gaining speed to 100 km / h per 19 seconds, and this indicator, to put it mildly, no. According to the passport, fuel consumption in urban mode with 402-m is equal to 14 l / 100 km, on the track it decreases to 8.8 liters. In fact, the winter "dozen" could "eat" and 17-18 l - K151 carburetor, which is completed 3110, rather "voracious", besides, it is capricious and requires accurate adjustment.

Filling capacity by car GAZ 3110:

engine oil - 5.5 l (for SMZ-402 and 4021 motors), 5.8 l (for DVS ZMZ-4062). The data is indicated for dry engine, when replacing the oil is required by approximately 0.5 l less;
fuel tank - 55 liters (in some 75 l);
cooling fluid in the radiator - 9.8 l;
oil in the gearbox - 0.85 l (4-st. KPP), 1.2 liters (5-st. CPP);
oil B. rear axle - 1.6 l;
the presence of lubrication in the steering gearbox is 0.4 liters (without GUR), 1.6 liters (with power steering).

"Volga" has long been required injector Engine, severe and pretty overall car clearly lacked a dynamic motor. ZMZ-406 - It is the engine that needs a model of GAZ 3110. It cannot be said that with the 406th machine it becomes much more economical, but the Volga accelerates with these DVS is much faster, the engine is felt in the engine. According to passport data, the "tenth Volga" with ZMZ-4062 has the following characteristics:

GAZ 3110 "Volga" with engine 406 (injector) is equipped only with a five-speed mechanical gearbox, fuel system Manager the electronic unit. Unlike the ZMZ-402, which has the lower arrangement of the camshaft and the gear drive of the timing, the 406th engine is equipped with a chain transmission (two chains) and two camshafts located on top, in the head of the cylinder block.

It should be noted that the timing chains at 406-M DVS - sick place, they stretch and rush quite often. The details of the gas distribution mechanism should be on mileage 70-80 thousand km, the first sign of the timing fault - the sound of "diesel" on idling. The big advantage of the motor is that when the chain breakdowns or the leakage of it in the teeth, the valve gears in the block is not bent, so the repair is not too expensive.

There is another lack of 4062 motors (and it is already more serious) - even with a slight overheating on the engine pierces gasket GBC., the surface of the head itself is deformed. In the event of a strong fixation of the gasket, the plane of the GB is no longer a perdition of milling (the head is strongly crucial), and then the part is subject to replacement, and the GBC ZMZ 406, unlike other parts for gas, is not suiced.

The technical characteristics of the ZMZ-4062 engine are as follows:

volume - 2280 cm³;
power - 131 liters. from.;
fuel system - injector type;
fuel used - AI-92 (AI-95);
the diameter of the sleeves is 92 mm;
compression - 9.1;
piston stroke - 86 mm.

ZMZ 406 became a basic engine for power aggregates Models 405 and 409, new models of motors are installed on Gazelle and UAZ cars. Before DVC ZMZ 402 in the 406th there are significant advantages over power and dynamics - with a smaller volume (2.3 l versus 2.445 liters) and a piston period (86 mm versus 92 mm) engine 406 (131 liters) significantly more powerful 402 (90 l. P.) And 4021 (100 l. P.).

Like another any car model, the Volga has its own characteristic diseases. Among the shortcomings of the machine should be noted:

corrosion exposure - especially quickly rust lower doors, rear arches, thresholds;
frequent breakdowns of the main brake cylinder, vacuum brake amplifier, injector sensors;
the hum of the main pair of the rear axle;
flow radiator cooling;
knock of hydrocomathers.

Other sores in the gas-3110 car also a lot - the quality of Russian spare parts is not too good. But many car owners forgive the car all its disadvantages, as it has very important advantages:

An inline four-cylinder engine is equipped with a complex microprocessor fuel injection and ignition control system (KMSud).

The cylinder block is cast from gray cast iron. Between the cylinders there are channels for coolant.

Cylinders are made without plug-in sleeves.

At the bottom of the block there are five supports of the native crankshaft bearings. The covers of the indigenous bearings are made of carpet cast iron and are attached to the block with two bolts.

The bearing caps are mounted together with the block, so they cannot be changed in places. On all covers, except for the lid of the third bearing, their sequence numbers are knocked out.

The lid of the third bearing in conjunction with the block is processed along the ends to install the hemisphere of the stubborn bearing.

The cover of the chain and the crankshaft crankshaft cover are brought to the ends of the block bolts.

Oil Carter is mounted below the block.

From above on the block installed the head of the cylinder block, cast from an aluminum alloy.

It has intake and exhaust valves. For each cylinder, four valves are installed, two intake and two graduation.

Inlet valves are located with right side Heads, and prom - with left.

Valve drive is carried out by two camshafts through hydraulic pushers.

The use of hydrotherapists eliminates the need to adjust the gaps in the valve drive, as they automatically compensate for the gap between camshafts and valve rods.

Outside on the housing of the hydrotrapist, there is a groove and an oil supply hole inside the hydrotrodeter from the oil highway.

The hydrotrode has a steel housing, inside which the guide sleeve is welded. In the sleeve installed a compensator with a piston.

The compensator is held in the sleeve with a locking ring. Between the compensator and the piston installed the expansion spring.

The piston rests on the bottom of the housing of the hydrotrode.

At the same time, the spring presses the reverse ball valve housing.

When the cam distribution Vala Does not click on the hydrotrodeter, the spring presses through the piston the body of the hydrotrode to the cylindrical part of the camshaft camshaft, and the compensator is to the valve rod, choosing the gaps in the valve drive.

The ball valve in this position is open, and the oil enters the hydrotherapler.

As soon as the camshaft camshaft turns and presses the pusher body, the housing drops down and the ball valve will close.

Butter located between the piston and the compensator begins to work as a solid.

The hydrotrode under the action of the camshaft camshaft moves down and opens the valve.

When the cam turning, stops pressing on the body of the hydrotrode, it moves up under the action of the spring, opening the ball valve, and the entire cycle is repeated again.

In the head of the block with a large tension, the seats and guide sleeves of the valves are installed.

In the lower part of the block of the block, combustion chambers are performed, in the top - the distribution shafts are located.

Aluminum covers are installed on the supports. The front cover is common to the supports of intake and exhaust camshafts.

Plastic stubborn flanges are installed in this lid, which are included in the grooves on the cervication shafts.

The covers are mounted together with the head of the block, so they cannot be changed in places. On all covers, in addition to the front, selected rooms are knocked out.

Distributional shafts are cast from cast iron. The cam and graduate shaft profiles are the same.

The fists are shifted by 1.0 mm relative to the axis of the hydrothels, which during the operation of the engine makes them rotate.

This reduces wear of the surface of the hydrotrode and makes it uniform. From above, the block head is closed with a lid cast from an aluminum alloy.

Pistons are also cast from aluminum alloy. On the piston's donkey, four deepening under the valves are performed, which prevent the piston blows on the valves in violating the phases of the gas distribution.

For proper Installation Piston in the cylinder on the side wall at the battle of the piston finger cast inscription: "Before." The piston is installed in the cylinder so that this inscription is facing the front of the engine.

On each piston are installed two compression and one oil slim ring.

Compression rings are cast from cast iron. The barrel-shaped working surface of the upper ring is covered with a layer of porous chrome, which improves the rings' host.

The working surface of the lower ring is covered with a layer of tin. On the inner surface of the lower ring there is a flow. The ring should be installed on the piston of this duct up, to the bottom of the piston.

The oil slimming ring consists of three elements: two steel disks and an expander.

The piston is attached to the connecting rod using the piston finger "floating type", i.e. The finger is not fixed in either piston, nor in the connecting rod.

From moving the finger is held by two spring retaining rings, which are installed in the grooves of the pistons of the pistons.

Steel rods forged, with a core of a foreign cross section. Bronze sleeve is pressed into the top head of the rod.

The lower head of the connecting rod with a lid, which is attached by two bolts.

The nuts of connecting rod bolts have self-locking threads and therefore do not stop.

The connecting rods are processed together with the connecting rod, and therefore they cannot be rearranged from one rod to another.

In the lower head, the connecting rod is installed thin-walled skeeping inserts. The crankshaft is cast from high strength cast iron. The shaft has eight counterweights.

From axial movement, it holds the stubborn semi-horses installed on the middle neck. A flywheel is attached to the rear end of the crankshaft.
