An internal combustion engine ( ), especially of a motor vehicle, is described which is provided with a combustion chamber ( ) 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. An exhaust-gas pipe ( ) is provided in which a catalytic converter ( ) is mounted. The engine ( ) is provided with an exhaust-gas recirculation from the exhaust-gas pipe ( ) to an intake manifold ( ). A control apparatus ( ) is provided for controlling (open loop and/or closed loop) operating variables of the engine ( ). The exhaust-gas recirculation rate of the exhaust-gas recirculation is controllable (open loop and/or closed loop) by the control apparatus ( ), inter alia, in dependence upon the temperature of the catalytic converter ( ).
