ABSTRACT:
An engine valve control mechanism (12) for varying the amount of opening and/or timing of a cylinder valve (16) in a valve gear train (14) of a multi-cylinder, internal combustion engine having an overhead camshaft (24) which actuates the valve via a rocker arm (18) pivotally bridged between a valve stem end (16e) and a hydraulic lash adjuster (31). The valve gear train portion for each intake is provided with a valve control mechanism by providing the camshaft with a high lift lobe (24c) and two low lift lobes (24a) for actuating the valve and by providing the rocker arm with a rigid link, two low lift cam roller followers (36) fixed to a shaft (40) rotatably mounted on the link, and a high lift cam follower (38) rotatably mounted on the shaft (40) and rotatable between first and second positions for respectively engaging and not engaging the high lift cam lobe (24c). A latch member (44) and a solenoid (54) control the position of the high lift cam follower (38).
