气缸垫是发动机的主要零件。气缸垫应能在长期高温高压条件下,保持气缸体与气缸盖之间的良好密封。气缸垫被压紧后,气缸垫的变形应能补偿气缸体和气缸盖由加工所造成的不平度。当气缸垫拆下后,应能恢复其弹性,以便下次继续使用。 Cylinder pad is the main part of the engine. Cylinder pad should be able to maintain a good seal between the cylinder block and the cylinder head under long-term high temperature and pressure conditions. After the cylinder cushion is compressed, the deformation of the cylinder cushion should be able to compensate for the unevenness caused by the machining of the cylinder block and the cylinder head. When the cylinder pad removed, should be able to restore its flexibility in order to continue to use the next time.
