ABSTRACT:
In order to achieve good sealing in both a cold and a warm engine by sealing features which are as simple as possible, an at least substantially metallic cylinder head gasket comprises a gasket plate with only one layer of sheet steel extending over the entire gasket plate, and around each combustion chamber opening of the gasket plate, a combustion chamber sealing element forming on at least one side of the gasket an elevation with a gasket sealing surface surrounding the combustion chamber opening in a closed manner for being pressed against an engine component sealing surface. The height profile of the gasket sealing surface corresponds prior to installation of the gasket to the topography of the sealing gap to be sealed off by the gasket when the gasket is installed, and the elevation has a metallic main body whose material is selected and whose cross section is designed such that the main body will not be deformable in its height under the maximum load occurring when the cylinder head gasket is installed and the engine is operating. At least one sealing bead is provided in the gasket plate, which surrounds at least one fluid opening of the gasket in a closed manner and is elastically deformable in its height.
