Abstract

The invention discloses a continuous variable valve lift apparatus and an engine provided with the same. A continuous variable valve lift apparatus may include a camshaft, a cam portion on which a cam is formed and to which the camshaft is inserted; a slider housing to which the cam portion is rotatably inserted and is movable with respect to the camshaft; a control portion selectively changing the position of the slider housing; and an output portion rotatable around a pivot shaft and to which a valve shoe is formed. The valve shoe drives a valve unit.

Description

[0001] Cross reference with related applications [0002] This application claims the rights and interests of Korean Patent Application No. 10-2015-0088630 filed on June 22, 2015, the entire content of which is incorporated herein by reference. Technical field [0003] The invention relates to a continuously variable valve lift device and an engine provided with the device. Background technique [0004] The statements in this section only provide background information related to the present invention and do not constitute prior art. [0005] The internal combustion engine generates power by burning the fuel in the combustion chamber in the air medium sucked into the combustion chamber. The intake valve is operated by a camshaft to suck in air, and the air is introduced into the combustion chamber while the intake valve is opened. In addition, the exhaust valve is operated by a camshaft, and the combustion gas is discharged from the combustion chamber while the exhaust valve is open...
