Abstract

An internal combustion engine is provided with 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 differentiated control and/or regulation of the performance quantities that influence the actual torque of the internal combustion engine as a function of a setpoint torque in both operating modes. A change in the actual torque 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.
