  • Patent number: 9097145
    Abstract: Disclosed is a continuously variable valve lift actuator of an engine. The continuously variable valve lift actuator of an engine changes rotating angles of a rocker arm and a lift arm having a four-bar link structure to control an intake amount of air of an intake valve based on a running state of a vehicle, and adjusts a location and a length of a link bar by taking into consideration a rotating direction of a cam shaft and interference according to layout of the engine to advance an open time of a valve. The continuously variable valve lift actuator of an engine can reduce pumping loss by controlling an intake amount of air by changing an elevating distance of a valve according to a running state of a vehicle, and the fuel efficiency and the efficiency of the engine can be improved by advancing the open time of the valve.
