The trend in the diesel engine industry is toward longer service life and higher reliability. This trend is accompanied by increased power ratings, stringent emissions standards, and improved fuel efficiency. Consequently, the functional requirements of cylinder head gaskets are often beyond the performance capabilities of traditional gasket materials (nonasbestos paper, graphite, etc.).An engineering effort focused on the functional sealing requirements of current production and future diesel engines, resulted in the development of Edge Molded Metal Plate (EMMP) Cylinder Head Gaskets. This paper examines the design and material considerations and concludes with the primary reasons for selecting EMMP gaskets.
