Abstract

A pre-chamber ignition system for a spark-ignited reciprocating piston internal combustion engine includes a housing where the housing is installable in a cylinder head of the spark-ignited reciprocating piston internal combustion engine and where the housing has a cavity. An ignition device is disposed in the housing and the ignition device projects into the cavity of the housing. A cover covers the cavity with respect to a combustion chamber of the spark-ignited reciprocating piston internal combustion engine and the cavity and the combustion chamber are connectable together in a gas-guiding manner by an aperture in the cover. The housing consists of a material having a thermal conductivity of more than 170 W/(m*K) and the cover consists of a material having a thermal conductivity of less than 170 W/(m*K).
