Abstract

A spark-ignited reciprocating piston internal combustion engine includes a pre-chamber ignition system with a housing which is installed in a cylinder head of the spark-ignited reciprocating piston internal combustion engine. An ignition apparatus is disposed in the pre-chamber ignition system and the ignition apparatus protrudes into a cavity in the housing. The cavity is covered by a cover with respect to a combustion chamber of the spark-ignited reciprocating piston internal combustion engine and the cover has at least one aperture which connects the cavity and the combustion chamber to one another in a gas-conducting manner. The housing has a volume and the at least one aperture has a jet cross section and a ratio of the volume to the jet cross section is greater than 100 and less than 300.
