Abstract
The present invention relates to a continuously variable valve lift system for engines, which can prevent deterioration of fuel efficiency due to a friction loss by a return spring even in a low lift operation state by making a high lift swing angle be larger than a low lift swing angle, easily implement the CVVL by reducing a lost motion angle to an optimum condition, and securely generate an advancing effect in spite of reduction of the lost motion angle. Further, the continuously variable valve lift system is easy and convenient to adjust a clearance of an oscillating cam link, prevent the clearance of the oscillating cam link from being accumulated, and has a convenience of workability in adjusting the clearance in a narrow engine room.
