ABSTRACT:
A steel 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 formed of first and second plates laminating together, a compressible member and a sealing device for sealing around the cylinder bore. The first plate includes a hole adjacent the cylinder bore. The hole is located under a part of the mouth plate to form an elongated strip between the hole and the cylinder bore. The compressible member is situated inside the hole to support the mouth plate. A bead is also formed at the elongated strip to support the mouth plate together with the wire ring. Accordingly, damage by movement of the mouth plate is substantially prevented.
