ABSTRACT:
A valve operation control system in an internal combustion engine, comprising an engine valve openably and closably supported on an engine body, a valve spring for biasing the engine valve in a valve closing direction, and valve driving means interposed between a valve-operating cam and the engine valve to transmit a force in the valve-opening direction provided by the valve-operating cam to the engine valve. The valve driving means includes a valve-opening resilient member for exhibiting a repulsive force in a direction to open the engine valve, and closed-position retaining means is interposed between the engine valve and the valve operating cam for retaining the engine valve at its closed position, with a valve-opening force provided by the valve-operating cam being accumulated by the valve-opening resilient member. The closed-position retaining means is arranged to be switchable between a retaining state and a releasing state to control the timing of opening the engine valve depending upon the operational condition of the engine.
