Abstract
An internal combustion engine (1), in particular for a motor vehicle, is described, that is provided with an injection valve (8), using which fuel can be directly injected into a combustion chamber (4) either in a first mode during an intake phase or in a second mode during a compression phase. In addition, a control unit (16) is provided for the control and/or feedback control of the fuel quantity injected into the combustion chamber (4), the control and/or feedback control being different in the two modes. The switchover from the first mode initially (26) to a transitional operation of the second mode and then (31, 37) to a normal operation of the second mode is effected by the control unit (16).
