The valve guide bracket drives the valve unit.

Description

[0001] Cross References to Related Applications [0002] This application claims the benefit of Korean Patent Application No. 10-2015-0088630 filed on June 22, 2015, the entire contents of which are hereby incorporated 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 merely provide background information related to the present disclosure and may not constitute prior art. [0005] An internal combustion engine generates power by burning fuel in a combustion chamber in a medium of air drawn into the combustion chamber. The intake valve is operated by the camshaft to draw in air, which is drawn into the combustion chamber while the intake valve is open. In addition, the exhaust valves are operated by the camshaft to expel combustion gases from the combustion chamber while the exhaust valves are open. [0006] Desired op...
