摘要

A method of manufacturing a cylinder head gasket comprising the steps of preassembling a main gasket body and a fire ring and then precompressing the gasket to alter the characteristics of one of the gasket body and fire ring, so that a portion of the available design head load will be taken up by each of the gasket body and fire ring when the precompressed gasket is assembled in an engine at the available design head load. The precompressed gasket fire ring displays different thickness and compression characteristics resulting from the precompression of the preassembled gasket, enhancing the capacity of the gasket effectively and consistently to seal a head and block at the available design head load.
