Abstract
The present invention is directed to a valve operation control apparatus for use in an internal combustion engine. The device comprises a cylinder with at least two intake or two exhaust valves, one of the two valves including a pause member for holding the valve in a closed position. The control apparatus comprises a control circuit operatively coupled to the pause member. The control circuit has at least two open degree sensors responsive to two different degrees of opening of a throttle valve of the engine and at least two engine speed sensors responsive to two different speeds of the engine, wherein the control circuit controls the operation of the pause member in response to predetermined combinations of the operation of the open degree sensors and the engine speed sensors.
