Abstract

Diese Ventilsteuerung ist für eine Brennkraftmaschine der Hubkolbenbauart mit mehreren Zylindern geeignet, bei der wenigstens eine Nockenwelle Ventile zur Gaswechselsteuerung in einem Brennraum der Brennkraftmaschine betätigt, wobei vorzugsweise ein Teil der Ventile in Abhängigkeit zumindest eines Parameters der Brennkraftmaschine bezüglich Hub durch mit der Nockenwelle zusammenwirkenden Schaltelementen verstellbar ausgebildet sind.This valve control is for an internal combustion engine of the reciprocating piston type with several Suitable cylinders, at least one camshaft valves for gas exchange control actuated in a combustion chamber of the internal combustion engine, preferably part of the Valves as a function of at least one parameter of the internal combustion engine with respect to the stroke adjustable by switching elements interacting with the camshaft are.

Zur Überprüfung der Funktion eines oder mehrerer der Schaltelemente werden Meßwerte der Nockenwelle detektiert und bei definierten Abweichungen als Funktionssignal angezeigt.Measured values are used to check the function of one or more of the switching elements the camshaft is detected and displayed as a function signal in the event of defined deviations.
