Abstract

Die Erfindung betrifft ein Verfahren zum Betrieb einer Kolbenbrennkraftmaschine mit Kraftstoffeinspritzung, insbesondere Kraftstoffeindirekteinspritzung, mit je Zylinder jeweils wenigstens einem Auslaßventil, das mit einer Abgasanlage in Verbindung steht, und wenigstens einem Einlaßventil, das mit einer Lufteinlaßanlage in Verbindung steht, und mit Mitteln zur Erhöhung des Ladedrucks in der Lufteinlaßanlage, das dadurch gekennzeichnet ist, daß eine Steuereinrichtung zur variablen Einstellung zumindest der Öffnungszeitpunkte der Einlaßventile vorgesehen ist und daß im unteren Drehzahlbereich über die Steuereinrichtung die Einlaß-Öffnet-Zeitpunkte der Einlaßventile so gestellt werden, daß eine Ventilüberschneidung mit dem Schließzeitpunkt der zugehörigen Auslaßventile gegeben ist und so der Zylinder vor dem Ladungswechsel im Bereich des oberen Totpunktes mit frischer Ladeluft gespült wird.The invention relates to a method for operating a piston internal combustion engine with fuel injection, in particular direct fuel injection, with each cylinder at least one exhaust valve, which communicates with an exhaust system, and at least one inlet valve, which communicates with an air intake system and with means for increasing the Boost pressure in the air intake system, which is characterized in that a control device for variably adjusting at least the opening timing of the intake valves is provided and that in the lower speed range via the control device, the inlet-opening times of the intake valves are set so that a valve overlap with the closing time of the given exhaust valves and so the cylinder is purged with fresh charge air in the region of the top dead center before the charge change.
