Continuously variable valve lift/timing apparatus

摘要

A continuously variable valve lift/timing apparatus includes: a cam provided on a camshaft; a swing arm rotatable about a first end connected to a cylinder head and includes a second end; an actuating arm which includes: a rotation shaft rotatably coupled to the second end; an output cam coupled to the rotation shaft and has an output surface; and an input roller connected to the rotation shaft and comes into contact with the cam, and of which a relative distance with respect to the rotation shaft is variable; a valve opening and closing unit which comes into contact with the output surface so as to be opened and closed; a swing arm control unit which varies a relative position of the second end; and a lift timing control unit which varies a relative position of the input unit.
