ABSTRACT:
A metal laminate type cylinder head gasket is installed in an engine having a cylinder block with a cylinder bore, a cylinder head with an auxiliary combustion chamber, and a mouth plate attached to the cylinder head. The gasket is basically formed of first and second plates laminating together, and a sealing device around the cylinder bore. The second plate is situated under the first plate and includes first and second beads. The first bead extends at least partly around the cylinder bore, and the second bead is located adjacent to and at a predetermined distance outwardly away from a part of a contour of the mouth plate. The second bead intersects the first bead at intersecting portions and includes a wide portion having a width wider than that of the intersecting portion. The tightening pressure applied to the second bead is concentrated at the intersection portions.
