Abstract

The present invention provides a continuously variable valve duration device and a related engine. The continuously variable valve duration device may include: a camshaft; a first cam portion and a second cam portion, and the first cam portion and the second cam portion Cams are respectively formed on the upper part, the camshaft is inserted into the first cam part and the second cam part, and the relative phase angle of the first cam part and the second cam part relative to the camshaft is variable; the first inner bracket and the second inner bracket a bracket that transmits the rotation of the camshaft to the first cam portion and the second cam portion, respectively; the slider housing unit, the first inner bracket and the second inner bracket are rotatably inserted into the slider housing unit, and the slider housing The relative position of the body unit with respect to the camshaft is variable; the control shaft, parallel to the camshaft, the control rod is eccentrically formed on the control shaft; the lifting device, the lifting hole and the rotation hole are formed on the lifting device; and the control part, The control shaft is selectively rotated to control the position of the slider housing unit.

Description

[0001] Cross-references to related applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2015-0178653 filed on December 14, 2015, the entire contents of which are hereby incorporated by reference. technical field [0003] The present disclosure relates to a continuously variable valve duration device and an engine provided with the continuously variable valve duration 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] Internal combustion engines generate 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, and when the intake valve is opened, the air is drawn into the combustion chamber. In addition, the exhaust valve is operated by the camshaft, and combustion gas is exhausted from the...
