Motortechnik: Alternativen der variablen Ventilsteuerung

Öffnungsdauer, Ventilhub und Bewegungsablauf beim Öffnen und Schließen der Ventile werden in der Regel durch die Form des Nockens bestimmt. Bei einem steilen Nocken ("scharfer" Nocken) wird das Ventil schnell geöffnet und geschlossen. Es bleibt zudem länger offen. Ist der Nocken hingegen eher eiförmig ausgelegt, wird das Ventil langsam angehoben und geschlossen. Es bleibt nur kurze Zeit voll geöffnet. Bei unsymmetrischer Auslegung bewirkt die flache, auflaufende Bahn am Nocken ein langsames Öffnen, die steil ablaufende Bahn ergibt ein längeres Offenhalten des Ventils und ein schnelleres Schließen. So kann der Konstrukteur einem Motor ganz bestimmte Charakteristika mit auf den Weg geben.
