The function of a car cylinder head is to seal the upper part of the cylinder, form a combustion chamber, and serve as a support for the camshaft, rocker arm shaft, and intake and exhaust pipes, bearing the action of high temperature and high pressure gas. The cylinder head sucks air into the cylinder, and the spark plug ignites the combustible mixture, driving the piston to do work, and exhaust gas is discharged from the exhaust pipe.
What is the function of a cylinder head? Its main function is to seal the upper part of the cylinder, forming the combustion chamber, and serving as a support for the camshaft, rocker arm shaft, and intake and exhaust pipes. It mainly sucks air into the cylinder, ignites the combustible mixture with a spark plug, drives the piston to do work, and exhaust gas is discharged from the exhaust pipe.
What is the function of a cylinder head? Maintenance and upkeep: Leakage in the cylinder head is mainly caused by inadequate sealing of the valves or the lower end face of the cylinder head. Therefore, if there is carbon accumulation on the sealing surface of the valve seat, it should be removed in a timely manner. If the sealing surface is too wide or there are grooves, pits, dents, etc., it should be repaired or replaced with a new valve seat according to its degree. The warping deformation of the cylinder head and damage to the cylinder gasket can also cause air leakage. In order to avoid warping of the cylinder head and damage to the cylinder gasket, it is necessary to tighten the cylinder head nuts in the specified order, and the tightening torque should meet the requirements. Water leakage is mainly caused by cracks in the cylinder head or inadequate sealing due to water blockage. To prevent cracking, after starting the engine, it is necessary to warm up the engine thoroughly and gradually increase the load; The engine cannot work under overload for a long time; In extremely cold areas, make sure to drain all cooling water after parking.
What is the function of the cylinder head? Installation requirements:
1. The disassembly process should start from top to bottom, from the outside to the inside, with components first and then parts.
2. When disassembling parts with the same shape and size, such as cylinders, pistons, piston pins, connecting rods, etc., they should be marked with identification numbers and orientations before disassembly.
3. When disassembling, if it is necessary to press or drive out the shaft sleeve and pin, the direction of the knockback should be identified first, and then a copper hammer or copper rod should be used to indirectly hammer it to avoid burrs or damage to the surface of the parts.
4. When disassembling parts, do not use too much force. When parts are difficult to disassemble, the cause should be identified before disassembling to avoid damaging the parts.
5. During the dismantling process, personnel should be assigned to carry out the work and avoid being replaced by others.
6. The dismantled parts should be classified and placed according to their accuracy to avoid collision and damage to accuracy.
7. For small parts (such as balls, springs, etc.), they should be installed on the main parts after cleaning to avoid loss.
8. After cleaning the removed parts, they must be coated with lubricating oil or soaked in oil to prevent rusting on the surface of the parts.
