Abstract
An engine valve operating system for an internal combustion engine comprises a rocker arm for transferring valve actuating effect from a driving cam to an engine valve such as an intake or exhaust valve. An elongate lever or fulcrum member is pivoted at its one end section and disposed in fulcrum contact with the side of the rocker arm opposite to the driving cam. Additionally, a hydraulic actuator is provided to control the pivotal location of the lever and therefore has a movable end section which is in contact with the other end section of the lever and movable in accordance with an engine operating condition, thereby greatly improving control response of the lever while rendering unnecessary a large capacity and sized actuator.
