Laser ignited pre-combustion chamber assembly

摘要

The present disclosure relates to a laser ignited pre-combustion chamber assembly (120) for gaseous fuel internal combustion engines. The pre-combustion chamber assembly (120) may comprise an optical window (34) configured to couple an ignition laser beam into a pre-combustion chamber (26) for providing an ignition point (36) within the pre-combustion chamber (26). The ignition point (36) may be offset a pre-combustion chamber axis (27) with an offset (140).
