Abstract

A gasket body has a combustion opening and a coolant opening close to the combustion opening to define a narrow region of the gasket between the openings. An inner armor layer has an inner C-shaped section folded over an edge of the combustion opening adjacent to the coolant opening. The inner armor layer has top and bottom portions extending over the top and bottom surfaces of the narrow region of the gasket body. An outer armor layer has an outer C-shaped section folded over the inner C-shaped section. The outer armor layer has top and bottom portions extending over the top and bottom portions of the inner armor layer. The bottom portion of the outer armor layer extends across the entire width of the bottom surface of the narrow region of the gasket body and has a second C-shaped section folded up and over an edge of the coolant opening adjacent to the combustion opening.
