Abstract

Eine Brennkraftmaschine hat einen Sammler, von dem ein Saugrohr hin zu einem Einlass eines Zylinders der Brennkraftmaschine geführt ist. Es umfasst ein Gaseinlassventil, das an dem Einlass des Zylinders angeordnet ist, und ein Gasauslassventil, das an dem Auslass des Zylinders angeordnet ist, zu dem ein Abgaskanal geführt ist. Ferner umfasst die Brennkraftmaschine ein Impulsladeventil, das stromaufwärts des Gaseinlassventils in dem Saugrohr ist und abhängig von seiner Schaltstellung (S) das Saugrohr freigibt oder verschließt. Zum Einstellen einer Abgasrückführrate wird das Impulsladeventil in seine Schließstellung (CL) gesteuert, während das Gaseinlassventil den Einlass des Zylinders noch freigibt. Anschließend wird das Impulsladeventil in seine Offenstellung (OP) gesteuert, nachdem das Gaseinlassventil den Einlass des Zylinders verschlossen hat und während es den Einlass des Zylinders wieder freigibt, wobei das Gaseinlassventil und das Gasauslassventil für einen vorgegebenen Kurbelwellenwinkelbereich (VO) sowohl den Einlass als auch den Auslass des Zylinders freigeben.An internal combustion engine has a collector from which a suction pipe is led to an inlet of a cylinder of the internal combustion engine. It includes a gas inlet valve disposed at the inlet of the cylinder and a gas outlet valve disposed at the outlet of the cylinder to which an exhaust passage is directed. Furthermore, the internal combustion engine comprises a pulse charging valve which is upstream of the gas inlet valve in the intake manifold and, depending on its switching position (S), releases or closes the intake manifold. For adjusting an exhaust gas recirculation rate, the pulse charging valve is controlled to its closed position (CL) while the gas inlet valve still releases the inlet of the cylinder. Subsequently, the pulse charging valve is controlled to its open position (OP) after the gas inlet valve closes the inlet of the cylinder and releases the cylinder inlet again, the gas inlet valve and the gas outlet valve for a given crank angle range (VO) both the inlet and the outlet Release the outlet of the cylinder.
