An engine and its cylinder head gasket

Abstract

This utility model discloses an engine and its cylinder head gasket. The cylinder head gasket of this utility model includes a cylinder head gasket body, and a groove is provided on the upper surface of the cylinder head gasket body. Sealing parts are provided on both the inner and outer sides of the groove, respectively defined as an inner sealing part and an outer sealing part. The groove on the upper surface of the cylinder head gasket body reduces the area of ​​the upper surface, increases the surface pressure of the sealing surfaces of the inner and outer sealing parts, and reduces cylinder head gasket deformation caused by heat conduction. The cylinder head gasket of this utility model has good sealing performance and can effectively improve the sealing performance of the high-temperature and high-pressure combustion chamber of medium and large engines, ensuring the normal operation of the engine.
