Abstract
A metallic gasket installed between confronting surfaces of engine components is improved in heat conduction between the components so as to reduce the adverse thermal influence to the engine. The metallic gasket used between the confronting surfaces of, for example a cylinder head and a cylinder block is composed of an annular raised portion defining inside a gas hole in alignment with an associated cylinder bore, and a surrounding metallic sheet connected to the annular raised portion. Both the annular raised portion and the surrounding metallic sheet are made of aluminum material to render the heat conduction between the components efficient. Thus the improved gasket can reduce the adverse thermal influence such as thermal deformation, thermal stress, and so on, whether the components are made of different materials or same materials.
