Brennkraftmaschine und Verfahren zum Steuern der Umschaltung des Betriebsmodus

The invention relates to an internal combustion engine provided with at least one cylinder (1) and comprising a fuel injection system, a controllable means for intake air charging (C) for supplying air under pressure to an air intake manifold, a control unit (4) for controlling the fuel injection system, a spark ignition system and the intake air charging means. The control unit is arranged to switch the engine from a first combustion mode using a higher manifold pressure to a second combustion mode using a lower manifold pressure, and further arranged to control the intake air charging means to cause a surge in the intake air charging means, in order to evacuate the higher manifold pressure. The invention further relates to a method for controlling the internal combustion engine and a vehicle provided with such an internal combustion engine.
