Abstract

An internal combustion engine in for a motor vehicle in (1) is described. The internal combustion engine (1) has an injection valve with which fuel can be injected directly into a combustion chamber either during a compression phase in a first operating mode or during an intake phase in a second operating mode. In addition, a control unit is provided for shifting between the two operating modes and for differential control and/or regulation of the performance quantities that influence the actual moment of the internal combustion engine in both operating modes as a function of a setpoint moment. A change in the actual moment during a shifting operation is determined by the control unit and at least one of the performance quantities is influenced by the control unit as a function thereof.
