ABSTRACT:
An improved heat gasket assembly for sealing the block and head of an internal combustion engine where the head mounts a precombustion chamber, and method of making that gasket assembly. The gasket assembly comprises a main gasket body and an armored fire ring mounted at the combustion openings. The fire ring provides a precombustion tab underlying the precombustion chamber, against which sealing occurs. To enhance that seal, spanner elements are positioned between the wire ring and the lower leg of the armor of the fire ring in the zones in which the periphery of the precombustion chamber overlie the wire ring. When the gasket assembly is compressed between the block and the head (and precombustion chamber) the spanner elements induce a more effective and consistent seal between the fire ring, the head, and the precombustion chamber regardless of whether the precombustion chamber is flush with, projects from, or is recessed with respect to, the head.
