Cylinder head gasket with seal coatings
摘要:
A metal gasket seals two engine members of an internal combustion engine. The metal gasket includes a metal gasket member extending substantially throughout an entire area of the engine members and has two surfaces to contact the engine members. At least two seal coatings are coated on the two surfaces of the gasket member to constitute sealing lines on the surfaces of the gasket member. One of the sealing lines on one surface of the metal gasket member is shifted from the other of the sealing lines on the other surface of the metal gasket member. Micro coatings are coated on the two surfaces of the gasket member. The thickness of the micro coating is less than that of the seal coating.
