The piston works under high temperature, high pressure, high speed and poor lubrication.

The role of the cylinder head is to seal the gas, form a combustion space with the piston, and withstand the role of high temperature and high pressure gas. The working condition of the cylinder head is: (1)the cylinder head is subjected to the action of high temperature and high pressure gas, and bears a large bolt pre-tightening force, resulting in large mechanical stress. (2)The structure of the cylinder head is complex, and the temperature field is seriously uneven, resulting in large thermal stress, which will cause cracks and overall deformation of the cylinder head
