Method for operating an internal combustion engine, having a main combustion chamber and an antechamber, with gas fuel.

摘要

The invention relates to, inter alia. a method for operating an internal combustion engine (10), having a main combustion chamber (16) and an antechamber (22), with gas fuel. A major amount of gas fuel is fed into the main combustion chamber (16) via the antechamber (22). An ignition amount of gas fuel is fed into the prechamber (22) before the piston (18) reaches top dead center to form an air-gas fuel mixture in the prechamber (22) that is richer than in the main combustion chamber (16). The air / gas fuel mixture in the prechamber (22) ignites by itself. The air / gas fuel mixture in the main combustion chamber (16) ignites by the self-ignited air / gas fuel mixture in the prechamber (22).
