Abstract
The invention relates to a method for operating an internal combustion engine operated with a self-ignitable fuel, with an approximately homogeneous fuel-air mixture being produced in the combustion chamber in the self-ignition ranges (CI), a high compression ratio suitable for a self-ignition of the fuel being provided and the combustion occurring in the self-ignition ranges (CI) predominantly by self-ignition. In order to control the start of combustion in the self-ignition range (CI) in the easiest possible way it is provided that in the self-ignition range (CI) the pressure and/or temperature of the homogeneous fuel-air mixture are set in such a way, preferably depending on the charge composition and/or charge temperature, that the self-ignition would be achieved only after the actually desired start of combustion in the zone of the upper dead center and the combustion of the homogeneous fuel-air mixture is initiated locally in the self-ignition range (CI) by an external energy impulse.
