Abstract

Bei einer variablen Ventilsteuerung für eine Hubkol­ ben-Brennkraftmaschine ist das Einlaßventil durch eine ro­ tierende Hubnockenwelle mittels eines um eine verschiebli­ che Lagerstelle verschwenkbaren Ventilhebels entgegen der Kraft einer Ventilfeder betätigbar. An dem Ventilhebel greift zusätzlich eine mit gleicher Drehzahl wie die Hub­ nockenwelle umlaufende Steuernockenwelle an, die die Schwenkbewegung des Ventilhebels abhängig von Kenn­ größen der Brennkraftmaschine steuert. With a variable valve control for a reciprocating piston ben engine is the intake valve through a ro ting lifting camshaft by means of a displaceable che bearing point opposite pivotable valve lever actuated by the force of a valve spring. On the valve lever also grabs one with the same speed as the stroke camshaft rotating control camshaft, which the Swiveling movement of the valve lever depending on characteristic Controls sizes of the internal combustion engine.
