Abstract
An internal combustion engine is equipped with a variable valve controlling system, in which the single actuator is disposed in a cylinder head on one side where one ends of the rocker-arm shafts are disposed, while enabling the single actuator to activate the rocker arms irrespective of the arrangement of the rocker-arm shafts. In the internal combustion engine, a hydraulic cylinder of a hydraulic actuator is disposed so as to transverse a timing chamber. Operation elements extend respectively from sidewalls of a plunger in the hydraulic cylinder, and activate respective rocker-arm shafts. In a motorcycle on which the engine is mounted, a frame member of a vehicle frame is disposed outside the hydraulic actuator.
