Ignition system for internal combustion engines

A spark ignited gaseous fuel internal combustion engine comprising:

• at least one cylinder movably accommodating an associated piston, the at least one cylinder and the associated piston defining a main combustion chamber for combusting an air/fuel mixture therein;
• and
• at least one ignition system, comprising:
• an ignition device having an igniting portion defining an ignition region, the ignition device being configured to initiate an ignition event in the ignition region for initiating a combustion process in the main combustion chamber;
• and
• at least one fuel supply channel configured to supply pressurized fuel into the ignition region for enriching the ignition region with fuel, wherein the pressurized fuel is supplied to the ignition region at crank angles between about 30° and about 0° before the ignition event is initiated by the ignition device.
