Abstract
A gasket for sealing a joint between the cylinder block and the cylinder head of a wet liner internal combustion engine comprises a pair of outer metal plates (1) having outwardly directed corrugations formed therein away from cylinder bore openings. A composite metal spacer plate (2) is disposed between the plates (1) and has a central soft metal layer and hard metal surface layers bonded or integral therewith. Characteristically the metal spacer plate (2) extends into proximity with the individual cylinder bore openings and is formed adjacent these openings on each axial face with circumferential serrations (2a) of V-shaped radial profile; the thickness of the spacer plate measured over the peaks of the serrations before the gasket is installed is somewhat greater than that of the remainder of the spacer plate while the thickness measured between the troughs of the serrations is significantly less than that of the remainder of the spacer plate.
