ABSTRACT:
A valve moving control apparatus for an internal combustion engine comprising a control device for switching at least one valve by controlling a driving condition of an intake/exhaust valve, a load detecting device, a switch control device for outputting a switch signal to the control device, and a gear shift detecting device. The gear shift detecting device 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 torque shock caused by switching.
