The Cylinder Head

The function of the cylinder head is to seal the cylinder, form a combustion space with the piston, and withstand the action of high temperature and high pressure gas. The cylinder head bears the mechanical load caused by the gas force and the tightening of the cylinder bolts, and at the same time bears a high thermal load due to contact with high-temperature gas. In order to ensure a good seal of the cylinder, the cylinder head must neither be damaged nor deformed. For this reason, the cylinder head should have sufficient strength and rigidity.
