Ventilantriebsvorrichtung für Brennkraftmaschine und Verfahren

摘要

The present invention relates to provide a valve moving apparatus for an internal combustion engine comprising a control device (28) for switching at least one valve by controlling a driving condition of an intake/exhaust valve, a load detecting device (17) , a switch control device for outputting a switch signal to the control device, and a gear shift detecting device (29). The gear shift detecting device (29) detects whether a gear is shifted to a relatively low gear in a gearbox. If the gear is shifted to a relatively low gear, a switching point for switching an actuation of the valve is shifted to a low load side in order to reduce shock caused by switching.
