ABSTRACT:
The invention concerns a method for operating an internal combustion engine (1, 18) having a plurality of combustion chambers (4), in the case of which the combustion chambers (4) are charged with fuel and air or with a fuel/air mixture. In order to prevent torque jumps from occurring when cylinders (3) of the internal combustion engine (1, 18) are shut down and when switching the operating mode of direct-injection internal combustion engines (18), it is proposed that the charging of the combustion chambers (4) with fuel and air or with a fuel/air mixture be controlled individually via open-loop or closed-loop control for each combustion chamber (4). In the case of a direct-injection internal combustion engine (18), a certain number of combustion chambers (4) can be operated with homogenous-charge operation, and the remaining combustion chambers (4) can be operated with stratified-charge operation in accordance with the level of torque required.
