Beam functioning fire ring

摘要

A beam functioning fire ring mounted in main gasket body combustion openings straddles the block and cylinder liner of an internal combustion engine and seals combustion gases on the liner and liquids on the block. The fire ring may have a pair of combustion gas sealing feet on the liner and a single foot on the block. The thickness of the beam diminishes providing greater sealing stress against the liner and less sealing stress against the block where the sealing requirements are less stringent.
