SUPPLY AND IGNITION DEVICE FOR A GAS ENGINE, AND METHOD FOR OPERATING A SUPPLY AND IGNITION DEVICE FOR A GAS ENGINE

摘要

The invention relates to a supply and ignition device (18) for a gas engine (10), comprising at least one injector (20) for directly injecting a combustion gas into a combustion chamber (12) of the gas engine (10), comprising a pre-combustion chamber (30) into which a fuel can be introduced, comprising a plurality of overflow openings (32) which are arranged such that they are distributed over the circumference of the supply and ignition device in the circumferential direction of the injector (20), and via which the pre-combustion chamber (30) can be directly fluidically connected to the combustion chamber (12), and comprising an external ignition device (33) for igniting a fuel-air mixture including the fuel introduced into the pre-combustion chamber (30), wherein the pre-combustion chamber (30), the overflow openings (32) and the external ignition device (33) are formed by a first unit (40), and wherein the injector (20) is formed by a second unit (42) that is separate from the first unit (40).
