Will the cylinder head affect the power?

2021-03-16

Since the cylinder head is a part of the combustion chamber, whether the design of the cylinder head is of high quality will affect the efficiency of the engine. The better the cylinder head, the higher the engine efficiency. Of course, the cylinder head will affect the power.

When too much carbon accumulates at the cylinder head plane and the cylinder head bolt holes nearby, the compressed high-pressure gas rushes into the cylinder head bolt holes or leaks out from the joint surface of the cylinder head and the body. There is a light yellow foam in the air leak. If the air leak is strictly prohibited, it will make a sound of "adjacent", and sometimes it may be accompanied by water or oil leakage.

The key to cylinder head air leakage is caused by poor sealing of the valve or the lower end of the cylinder head. Therefore, if there is carbon deposit on the sealing surface of the valve seat, it should be removed immediately. If the sealing surface is too wide or grooves, pits, dents, etc., should be repaired or replaced with a new valve seat according to the degree. Cylinder head warping deformation and cylinder head gasket damage also affect air leakage. To prevent cylinder head warping and cylinder head gasket damage, the cylinder head nuts must be tightened in a limited order, and the tightening torque should meet the requirements.
