Abstract
Ventilsteuerungssystem (2) zur Ansteuerung von Gaswechselventilen (4) eines Verbrennungsmotors mit sowohl einer elektrohydraulischen Ventilhubsteuereinrichtung (28) mit einem ein Steuerventil (32) umfassenden hydraulischen System (30) zum gesteuerten Übertragen der Bewegung mindestens einer an einer Nockenwelle (8) angebrachten Nocke (26) auf mindestens eines der Gaswechselventile (4), derart, dass innerhalb einer Ventilsteuerungshüllkurve (42, 43) mittels des Steuerventils (32) eine Ventilerhebungskurve (44, 45) einstellbar ist, als auch mit einer Nockenwellenverstelleinrichtung (14), mittels derer die Winkelposition zwischen einer Kurbelwelle (12) und der Nockenwelle (8) verstellbar ist, derart, dass die Ventilsteuerungshüllkurve (42, 43) verschoben wird, sowie mit einer Steuereinheit (16), die derart ausgelegt ist, dass sie in Abhängigkeit von aktuellen Anforderungen wahlweise oder in Kombination die Ventilsteuerungshüllkurve (42, 43) über die Nockenwellenverstelleinrichtung (14) verschiebt und die Ventilerhebungskurve (44, 45) über die Ventilhubsteuereinrichtung (28) einstellt.
