Cylinder head: device and purpose

The head of the block of cylinders is the major detail for each modern engine. GBC manages absolutely all power plants, whether it's a diesel car or a gasoline. Of course, there are differences between them-the degree of compression and the type of fuel, but the device and the principle of the head of the unit do not change from this. Therefore, today we will analyze the general construction of this element.

Mechanism and principle of operation

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

• Valves for gas distribution, namely intake and exhaust;
• Spark plugs (in the case of gasoline) or injectors (in the case of a diesel engine);
• Combustion chamber of the fuel-air mixture.

Based on the photo provided at the very beginning of the article, we see that the cylinder head is a structural part of the engine (in fact, a large aluminum cover) with pressed 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 engine head and the unit are structurally connected together by means of a special fireproof steel-asbestos gasket. The latter eliminates the possibility of gas escaping through the junction of devices and loss of compression. It should be noted that this gasket, in spite of its primitive design, is very important for the car. In the event of loss of its sealing properties, the performance of the entire engine may deteriorate. First, the phenomenon of compression will occur, the motor will lose its power, and then completely stop working. The thrust of the car is stopped due to unauthorized outflow of gases from the camera. And given that the internal combustion engine produces a high degree of compression (about 2 thousand atmospheres on diesel and 100 on gasoline engines), the loss of power can be significant.

The head of the cylinder block (GAZ 3302 including) is also part of the KSM, so its relationship with the engine is immediate.

Features of maintenance

Every detail, however reliable it may be, is sooner or later exposed to wear, despite the fact that the head of the cylinder block (VAZ-2110 including) can last from 200 to 400 thousand kilometers. This does not exclude the possibility of its deformation and wear before. As a rule, this is due to frequent engine overheating, but the cylinder head may break due to the untimely replacement of the gasket. Therefore, to ensure that the head of the unit lasts as long as possible, first, 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 inlet and exhaust bars it deposits. With these simple tips, your engine will last a long time and without any breakdowns.
