What is the function of a car's cylinder head?

The function of a car's cylinder head is to seal the upper part of the cylinder, forming the combustion chamber, and to support the camshaft, rocker arm shaft, and intake and exhaust pipes, withstanding the effects of high-temperature and high-pressure gases. The cylinder head draws air into the cylinder, the spark plug ignites the combustible mixture, driving the piston to work, and exhaust gases are discharged from the exhaust pipe.
What is the function of the cylinder head? Its main function is to seal the upper part of the cylinder, forming the combustion chamber, and to serve as a support for the camshaft, rocker arm shaft, intake pipe, and exhaust pipe. It mainly draws air into the cylinder, uses a spark plug to ignite the combustible mixture, drives the piston to work, and exhaust gases are discharged from the exhaust pipe.
What is the function of the cylinder head? Maintenance and upkeep: Cylinder head leaks are mainly caused by poor sealing of the valves or the lower end face of the cylinder head. Therefore, if there is carbon deposit on the valve seat sealing surface, it should be removed promptly. If the sealing surface is too wide or has grooves, pits, dents, etc., it should be repaired or replaced with a new valve seat according to its condition. Warping of the cylinder head and damage to the cylinder gasket can also cause leaks. To avoid warping of the cylinder head and damage to the cylinder gasket, the cylinder head nuts must be tightened in the specified order, and the tightening torque must meet the requirements. The main cause of water leakage is cracks in the cylinder head or poor sealing due to water blockage. To prevent cracking, after starting the engine, it must be fully preheated, and the load must be gradually increased; the engine cannot operate under overload for a long time; in extremely cold areas, the coolant must be drained after parking.
What is the function of the cylinder head? Installation requirements:
1. The disassembly process should be from top to bottom, from outside to inside, components first, then parts.
2. When disassembling parts of the same shape and size, such as cylinders, pistons, piston pins, connecting rods, etc., the identification number and direction should be marked before disassembly.
3. When disassembling, if it is necessary to press out or knock out bushings or pins, the direction of rebound should be identified first, and then indirect tapping should be performed with a copper hammer or copper rod to avoid burrs or damage to the surface of the parts.
4. When disassembling parts, do not use excessive force. When parts are difficult to disassemble, the cause should be investigated before disassembly to avoid damaging the parts.
5. During the disassembly process, a designated person should be responsible, and others should not be allowed to substitute.
6. Disassembled parts should be placed according to their precision classification to avoid collisions and damage to precision.
7. Small parts (such as ball bearings, springs, etc.) should be installed on the main parts after cleaning to prevent loss.
8. After cleaning the disassembled parts, they must be coated with lubricating oil or immersed in oil to prevent rust on the surface of the parts.
