Abstract

An internal combustion engine (1), especially of a motor vehicle, is described. The engine (1) is provided with a combustion chamber (4) into which fuel can be injected in a first operating mode during a compression phase and in a second operating mode during an induction phase. The engine (1) is provided with a control apparatus (18) for switching over between the operating modes. The engine (1) includes an exhaust-gas recirculation having an exhaust-gas recirculation valve (14). The engine (1) is switched by the control apparatus (18) into the first operating mode when the exhaust-gas recirculation valve (14) is jammed in the open state.
