Cylinder head: device and purpose

The cylinder head is the most important part for every modern engine. The cylinder head is equipped with absolutely all power plants, whether it is a diesel car or a gasoline one. Of course, there are differences between them - the degree of compression and the type of fuel, but the device and principle of operation of the block head do not change from this. Therefore, today we will analyze the general design of this element.

The device of the mechanism and the principle of operation

Despite its importance in the operation of the engine, the cylinder head has a very simple design. This mechanism consists of such parts as:

• gas distribution valves, namely inlet and outlet;
• spark plugs (for petrol) or injectors (for diesel);
• air/fuel mixture combustion chamber unit.

Based on the photo provided at the very beginning of the article, we see that the cylinder headis a structural part of the engine (in fact, a large aluminum cover) with pressed-in valve seats and guide bushings. It should be noted that the axes of these parts must completely coincide with each other, otherwise the entire crank mechanism will fail.

The ICE head and block are structurally interconnected using a special refractory steel-asbestos gasket. The latter excludes the possibility of gases escaping through the junction of devices and loss of compression. It should be noted that this gasket, despite its primitive design, is very important for the car. If its sealing properties are lost, the operation of the entire engine may deteriorate. First, a compression phenomenon will occur, the motor will lose its power, and then it may stop working altogether. The draft of the car stops due to unauthorized release of gases from the chamber. And given that a high compression ratio is formed inside the internal combustion engine (about 2 thousand atmospheres on diesel engines and 100 on gasoline engines), the loss of power can be significant.

The cylinder head (including GAZelle 3302) is also part of the KShM, so its relationship with the engine is direct.

Maintenance Features

Each part, no matter how reliable, sooner or later wears out, despite the fact that the cylinder head (VAZ-2110 included) can last from 200 to 400 thousandkilometers. This does not exclude the possibility of its deformation and wear earlier. As a rule, this happens due to frequent overheating of the engine, but the cylinder head may also break due to untimely replacement of the gasket. Therefore, in order for the block head to last as long as possible, firstly, do not overheat the motor and do not try to cool it with water from above. Secondly, regularly change and check the condition of the gasket. The same applies to the mounting bolts. Next, do not forget about the seasonal cleaning of the valves of the intake and exhaust strokes of carbon deposits. By following these simple tips, your engine will last a long time and without any breakdowns.
