Abstract
PURPOSE: To prevent over-swirl and improve anti-knocking performance of an engine, by making the lift of a variable-lift intake valve maximum at the time of low-speed, high-load operation of the engine.
CONSTITUTION: Through the detection of engine load P and engine speed Q, an output signal is given to a control circuit 28 at the time of low-speed, full-load operation of the engine. By the control circuit 28, a reversible motor 27 is turned in normal or reverse direction depending on the flow rate of intake air. This causes a gear 25 to turn by the aid of a worm gear 26, so that a roller 19 supported by a lever 24 causes a relative displacement to an arm 18. This displacement of the roller 19 changed the position of fulcrum point A of the arm 18, so that the lever ratio of the arm 18 is varied and the lift of an intake valve 5 is change resultantly.
