Cylinder head gasket arrangements for engine assemblies

摘要

A cylinder head gasket arrangement for an engine assembly is disclosed. The engine assembly (10) comprises a cylinder block (12) having defined therein at least one cylinder barrel (1, 2) and a cylinder head (14) adapted to be attached to the cylinder block. The arrangement includes a cylinder head gasket (18) that is adapted to be compressed between the cylinder head and the cylinder block. The head gasket (18) comprises a sheet member (20) supporting a sealing ring (22) adapted to seal around the cylinder barrel. The sealing ring (22) is adapted to follow, around at least a portion of the cylinder barrel (1, 2), a curvilinear path lying substantially along a cylinder block neutral fibre (N/F) associated with the cylinder barrel.
