Abstract

An internal combustion engine, in particular for a motor vehicle, is described. The internal combustion engine is provided with a control unit for determining a setpoint fuel mass and/or a setpoint air mass as a function of a setpoint torque. The control unit is also provided for transitioning from a first operating mode to a second operating mode of the internal combustion engine. An actual torque is determined by the control unit during the transition to the second operating mode of the internal combustion engine. A torque difference between the setpoint torque and the actual torque is also calculated by the control unit. Finally, the setpoint fuel mass and/or the setpoint air mass is controlled by the control unit as a function of the torque difference.
