Abstract

Bei einer Hubkolbenbrennkraftmaschine wird in den Zylindern ein brennbares Kraftstoffgemisch mit Kraftstoff und Frischgas gebildet, wobei die Zuführung des Frischgases durch Einlaßkanäle und die Abführung von Verbrennungsabgasen durch Auslaßkanäle erfolgt, welche von Einlaßventilen und Auslaßventilen freigebbar sind, die zur Durchführung des Ladungswechsels von einem Ventiltrieb angesteuert werden. In einem Teil des Lastbereiches der Brennkraftmaschine ist eine Betriebsart mit Fremdzündung (Otto) vorgesehen mit Gemischzündung durch eine Zündkerze. In einem anderen Lastbereich wird die Brennkraftmaschine mit einer Kompressionszündung (RZV) des Gemisches betrieben, bei welcher die Steuerung der Gaswechselventile derart verändert wird, daß Verbrennungsabgase im Brennraum zurückgehalten und beim folgenden Arbeitsspiel des Zylinders an der Frischgemischbildung teilnehmen. DOLLAR A Um mit einfachen baulichen Mitteln Klopfen und Laufungleichförmigkeit der Brennkraftmaschine insbesondere beim Wechsel der Betriebsarten zwischen Fremdzündungsmodus (Otto) und der Betriebsart mit Kompressionszündung (RZV) zu vermeiden, ist erfindungsgemäß vorgesehen, die Phasenlage (PHI) der Öffnungsvorgänge der Gaswechselventile im Arbeitszyklus zu verändern.In a reciprocating internal combustion engine, a combustible fuel mixture with fuel and fresh gas is formed in the cylinders, wherein the supply of fresh gas through intake ports and the discharge of combustion exhaust gases through outlet channels, which are releasable from intake valves and exhaust valves, which are controlled to perform the charge exchange of a valve train , In a part of the load range of the internal combustion engine, a mode with spark ignition (Otto) is provided with mixture ignition by a spark plug. In another load range, the internal combustion engine is operated with a compression ignition (RZV) of the mixture, in which the control of the gas exchange valves is changed so that combustion exhaust gases retained in the combustion chamber and participate in the following working cycle of the cylinder in the fresh mixture formation. DOLLAR A to avoid simple structural means knocking and nonuniformity of the internal combustion engine especially when changing modes between spark-ignition (Otto) and compression ignition (RZV), according to the invention provides to change the phase position (PHI) of the opening operations of the gas exchange valves in the work cycle ,
