Abstract

An internal combustion engine (1), especially for a motor vehicle, is described. The engine has an injection valve (8) with which fuel can be injected directly into a combustion chamber (4) either in a first operating mode during a compression phase or in a second operating mode during an induction phase. A control apparatus (16) is provided for switching over between the two modes of operation and for differently controlling (open loop and/or closed loop) the injection duration in the two modes of operation, the injection duration influencing the injected fuel mass. With the control apparatus (16), the injection duration (ti) can be influenced by a function with the switchover from the first operating mode (VH) into the second operating mode (SH).
