Patent ID: 12006904

Abstract:
A spark-ignited reciprocating piston internal combustion engine may include a pre-chamber ignition system which is arranged in the cylinder head of the reciprocating piston internal combustion engine and in which an ignition device is arranged, comprising an ignition electrode in a housing, said ignition electrode protruding into a cavity of the pre-chamber ignition system. The cavity is covered from the combustion chamber of the reciprocating piston internal combustion engine by a cover, and the cover has at least one first opening which connects the cavity and the combustion chamber together so as to conduct gas. A metal transverse brace with at least one second opening, which connects opposite sides of the housing together, is arranged in the cavity in the region of the ignition electrode, wherein the metal transverse brace is made of a first metal material in a central region and a second metal material in a region contacting the housing.
