Abstract

An internal combustion engine , particularly for a motor vehicle, which is provided with an injector (8) with the assistance of which fuel can be injected directly into a combustion chamber either in a first operating mode, during an induction period, or in a second operating mode, during a compression period. Furthermore, a control unit is provided for determining the air mass supplied to the combustion chamber , and for differently controlling and/or regulating the fuel mass injected into the combustion chamber in both operating modes. The control unit switches over between the first operating mode and the second operating mode as a function of the air mass supplied to the combustion chamber.
