A method for operating an internal combustion engine especially of a motor vehicle is described wherein fuel is injected directly into the combustion chamber either in a first operating mode during a compression phase or in a second operating mode during an induction phase. The fuel mass (mK), which is to be injected into the combustion chamber, is determined in both modes of operation, inter alia, in dependence upon a computed desired torque (Mdes) which is to be outputted by the engine. An injection duration (ti in ms) is determined from the fuel mass (mK) which is to be injected. Then, an injection angle (alphai in degrees) is determined from the injection duration (ti in ms) in dependence upon the rpm (nmotor) of the engine (1) Finally, the fuel is injected into the combustion chamber during the injection angle (alphai in degrees).
