Abstract
A method and system for igniting a lean fuel mixture in a main chamber of an internal combustion engine by igniting a rich air-fuel mixture in a pre-combustion chamber which is fuelled using a controlled valve. For a stable and consistent ignition of the main chamber and simultaneous reduction of emission of the internal combustion engine, a closed loop control adjusts the fuel amount and the fuelling time for the pre-combustion chamber in order to achieve a light off in an optimal time window and by sufficient ignition energy.
