Abstract:
1. A metallic cylinder head gasket for an internal combustion engine having at least one combustion chamber, the gasket comprising: at least one sheet-metal layer having an outer edge, the at least one sheet-metal layer defining at least one opening corresponding to the at least one combustion chamber of the internal combustion engine, the at least one opening extending transversely through the at least one sheet-metal layer and having an edge, the at least one sheet-metal layer defining at least one bore corresponding to the at least one opening, the bore defining an axis and extending from the outer edge to the edge of the opening; a membrane sealing the at least one bore at a combustion-chamber side of the at least one bore proximate to the edge of the at least one opening, the membrane being adapted for exposure to a gas pressure of the combustion chamber; and a pressure sensor disposed in the sheet-metal layer, the pressure sensor being pressurized axially relative to the at least one bore by movement of the membrane by the gas pressure of the combustion chamber.
