A continuously variable valve actuation (CVVA) system may include a driving cam rotated by a driving force transmitted from a crankshaft, and a driven cam pressed by the driving cam to be rotated around a first end thereof serving as a rotational axle of the driven cam, wherein the driven cam has a cam face at a second end thereof so as to press and open a valve when rotated, and wherein a vertical distance between the rotational axis of the first end of the driven cam and a rotational axis of the driving cam is configured to be adjusted by moving a position of the rotational axis of the first end of the driven cam. |
