1 Cylinder pad
also known the cylinder head gasket located between the cylinder head and the cylinder bank of the cylinder block. Its function is to fill the microscopic pores between the cylinder block and cylinder head, with a joint surface to ensure a good seal, thus ensuring the sealing of the combustion chamber water jacket and the cylinder leakage preventing leakage.
With the strengthening of the internal combustion engine, the thermal and mechanical loads are increasing, the cylinder head gasket sealing increasingly important. Structure and material requirements are: having a sufficient strength, heat resistance and gas at high temperature and pressure conditions of high corrosion effect. A lot of damage or deterioration, corrosion-resistant. Has a certain elasticity, can compensate for unevenness of the junction surface, in order to ensure sealing, long service life.
