ABSTRACT:
Method and apparatus for suspending valve actuation for use in an internal combustion engine is disclosed. Each of intake and exhaust valves is normally actuated by a rocker arm operated by a cam in synchronism with an engine operation. The rocker arm is supported at one end by a supporting member held to a cylinder head by means of a retaining member. The supporting member is selectively floatable with respect to the cylinder head to thereby effect suspension of valve operation. The supporting member is then held at a position where sliding contact between the rocker arm and the cam is prevented.
