Abstract
An internal combustion engine ( ), especially for a motor vehicle, is described. The engine has an injection valve ( ) with which fuel can be injected directly into a combustion chamber ( ) either in a first operating mode during a compression phase or in a second operating mode during an induction phase. A control apparatus ( ) 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 ( ), 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).
