Catalysis unit for use in cylinder-head gasket, has substrate with coating containing catalytically active material, where catalysis unit is arranged in combustion chamber area of internal combustion engine

摘要

The catalysis unit (134) has a substrate (136) with a coating containing catalytically active material. The substrate is suitable for arrangement in a recess at a peripheral surface of a cylinder of an internal combustion engine. The catalysis unit is arranged in a combustion chamber area of the combustion engine. The catalysis unit is arranged in an annular gap at a fire land of a piston of the combustion engine. An independent claim is also included for a cylinder-head gasket for an internal combustion engine, includes a catalysis unit.
