Head gasket protecting device for internal combustion engine

Abstract

Abstract PURPOSE:To enable to obtain durability even if an inexpensive material is used for a head gasket by interposing the gasket between a cylinder head and a cylinder and adding a protective member for sealing the gasket from a combustion chamber. CONSTITUTION:A head gasket 24 is interposed between a cylinder 21 and a cylinder, i.e., a cylinder block or cylinder liner 23. A heat gasket protective member 25 formed annularly of ceramics is arranged between the upper surface of the cylinder liner 23 and an annular groove 21a formed on the head 21, thereby sealing the gasket 24 from a combustion chamber 26. In this manner, high temperature gas in the chamber 26 can prevent the direct contact with the gasket 24, thereby reducing the thermal load of the gasket 24. Accordingly, durability can be maintained while the gasket 24 is formed of an inexpensive usual material, and the cost can be reduced.
