This paper describes a new variable valve control device called VEL (Variable Valve Event and Lift Control Device), which enables continuous control of both valve events (opening duration) and valve lifts, from the lowest lift or deactivation state (0) to a long event and high lift state. VEL is composed of two subsystems. One is a mechanical valve train system, which converts crankshaft rotation into output cam oscillation via a transmission mechanism involving a rocker arm. The valves are moved by the output cam oscillation. The other is an electric powered actuator system, which varies valve events and lifts according to driving conditions by controlling the angular positions of a control shaft. This control shaft has a eccentric control cam inserted into the fulcrum cylinder of the rocker arm, so as to change the state of the transmission mechanism and the output cam.
