Ignition system for internal combustion engines

摘要

The present disclosure generally relates to a method for operating a gaseous fuel internal combustion engine including at least one main combustion chamber (8) and at least one ignition device (34) configured to initiate an ignition event within the ignition region (38). The disclosed method may comprise supplying pressurized fuel to the ignition region (38) at times between about 30° to about 0°, particularly between about 10° to about 2° crank angle before the ignition event is initiated by the ignition device (34) for enriching the ignition region (38) with fuel, and initiating an ignition event in the ignition region (38) for combusting the enriched air/fuel mixture within the ignition region (38).
