Abstract

A cylinder head gasket is disclosed having a carrier layer, in which at least one through-opening for a combustion chamber is located, and a combustion chamber sealing element, which is inserted in the through-opening and extends in an intrinsically closed manner. In some examples, at least one gap is formed at least in some sections between the carrier layer and the combustion chamber sealing element, the gap extending around the combustion chamber sealing element at least in some sections. Further, in some example, the carrier layer has at least one slot-like or groove-like channel, which extends from the at least one gap between the carrier layer and the combustion chamber sealing element to the outer edge of the carrier layer.
