Abstract
A continuously variable valve lift device for a vehicle is provided, which includes a drive shaft rotating in association with a crank shaft and having a drive cam formed on an outer periphery thereof, a locker arm shaft provided apart from the drive shaft and having one end that supports a rocker arm rotating and rocking in association with the drive cam, output cams rotatably installed on the drive shaft to interlock with the other end of the rocker arm, and a variable drive part straightly moving the rocker arm shaft in a vertical direction of the rocker arm shaft to vary a valve lift. When a valve is shifted from the high-lift state to the low-lift state, a pumping loss is reduced to improve the fuel consumption ratio. Also, since an advance function is provided, an exhaust-side CVVT can be deleted to greatly reduce the manufacturing cost.
