    摘要： In a VVA apparatus for an internal combustion engine wherein the position of contact of a cam face of a VO cam with respect to the top face of a valve lifter is changed in accordance with a change in a rocking fulcrum of a rocker arm to alter the valve lift, the maximum valve lift is obtained in a first rotated position of a control shaft where an axis of a control cam is adjacent to a driving shaft. The minimum valve lift is obtained in a second rotated position of the control shaft where the axis of the control cam is positioned near a first pivotal point of the rocker arm and a crank arm with respect to a first line connecting the axis of the control shaft and the axis of the control cam upon the maximum valve lift.

    摘要： There is provided a system for controlling an intake valve (53) of an internal combustion engine, including a variable valve mechanism (10) having a control shaft (12) to continuously vary a valve lift amount of the intake valve according to a rotational angle of the control shaft and an actuator (41) to drive the control shaft, and a control unit (50) that controls the actuator so as to set the control shaft to a first rotational angle position at which the valve lift amount takes a first value during an engine idling period and to a second rotational angle position at which the valve lift amount takes on a second value larger than the first value to provide a required intake quantity to start the engine during a time from the beginning of an engine speed decrease period, through an engine stop period, until the completion of a cranking period of the engine.
