Steel laminate type cylinder head gasket

摘要

A steel laminate gasket of the invention is installed in an engine with an auxiliary combustion chamber. The gasket comprises a first plate having at least one first sealing area around a cylinder bore and at least one second sealing area adjacent the first sealing area, on which a mouth plate for defining the auxiliary combustion chamber is placed, and at least one second plate situated adjacent to the first plate. The first plate is provided with a plurality of curved beads disposed at a predetermined distance away from each other and situated inside and outside the second sealing area. The beads are formed so that a recovery amount of the bead when pressurized decreases gradually from an inner bead to an outer bead.
