Design Methodology for Automotive Multi-Layer Steel Cylinder Head Gaskets

Automotive cylinder head gaskets today must not only ensure a dry joint, they must also assist in minimizing cylinder bore and cam journal distortion, decrease crevice volume to help meet stringent emissions requirements, and have the durability to perform well over extended warranty periods. In order to accomplish these varied goals, Multi-Layer Steel gaskets are proving to be the design of choice in an increasing number of automotive cylinder head gasket applications. This paper will discuss how and why a specific design methodology for multi-layer steel cylinder head gaskets successfully addresses today's engine manufacturers' requirements and shows additional promise for the future.
