Cylinder head gasket with step regulation layer

摘要

A cylinder head gasket for an internal combustion engine is formed of first and second metal plates laminated together. The first plate has a first hole, a first bead surrounding the first hole, and an inner portion extending from an edge of the first hole to an inner side of the first bead. The second plate has a second hole, and a second bead surrounding the second hole and located above the inner portion. When assembled, the first bead faces the second plate and the second bead faces the first plate. A step regulation layer formed of resin is deposited on at least a part of the inner portion of the first plate such that the second bead is placed on the step regulation layer. The surface pressure for the first bead can be easily adjusted by the step regulation layer.
