Abstract:
A method for operating an internal combustion engine operated with a self-ignitable fuel, with an approximately homogeneous fuel-air mixture being produced in a combustion chamber in at least one self-ignition range, a high compression ratio suitable for a self-ignition of the fuel being provided and the combustion occurring in the self-ignition range predominantly by self-ignition, wherein in the self-ignition range the pressure or temperature of the homogeneous fuel-air mixture are set in such a way, 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 by an external energy impulse.
