Optimum Design of Cylinder Head Gasket and Related Techniques

Abstract

The trend in high performance of automotive engines in recent years has been accompanied by a movement toward more compact size and lighter weight. This has created an ever more severe environment for cylinder head gaskets, demanding complex and difficult technological countermeasures. In order to bring about necessary improvements in head gaskets, computer simulation was used to analyze their behavior and to carry out analysis of such matters as head rigidity and methods for tightening head bolts. This has made possible development of a highly reliable head gasket, and of related technology.
