Abstract
An internal combustion engine ( ), especially for a motor vehicle, is described. The engine is provided with an injection valve ( ) with which fuel can be injected directly into a combustion chamber ( ) in a first operating mode during a compression phase or in a second mode of operation during an induction phase. A control apparatus ( ) is provided for switching over between the two modes of operation and for the different control (open loop and/or closed loop) in the two modes of operation of the operating variables, which influence the outputted torque of the engine ( ), in dependence upon a requested torque (mi). The fuel mass, which is to be injected in the first mode of operation, can be determined by the control apparatus ( ) in dependence upon the operating parameters of the engine ( ) which form the basis of the injections of the second operating mode.
