Abstract

The invention discloses a continuously variable valve timing device and an engine provided with the device. The device may include: a camshaft; a first and a second cam part, and two cams are formed to the first and second cam parts, the camshaft is inserted into the first and second cam parts, the relative phase angles of the first and second cam parts with respect to the camshaft are variable; the first and second inner brackets, which respectively transmit the rotation of the camshaft To the first and second cam parts; first and second slider covers, into which the first and second inner brackets are rotatably inserted, respectively, the relative positions of the first and second slider covers with respect to the camshaft are variable the cam cap; it rotatably supports the first and second cam parts together with the cylinder head, the slider cover is slidably mounted to the cam cap; the control shaft, which is arranged parallel to the cam shaft and selectively makes the first and second cam parts a slider housing that moves; and a control portion that selectively rotates the control shaft to change the position of the inner bracket.

Description

[0001] Cross References to Related Applications [0002] This application claims priority and benefit from Korean Patent Application No. 10-2015-0088631 filed on June 22, 2015, the entire contents of which are incorporated herein by reference. technical field [0003] The invention relates to a continuously variable valve timing device and an engine equipped with the device. Background technique [0004] 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. [0005] Optimal operation of the intake and exhaust valves depends on the engine speed. That is, the optimum lift or optimum opening / closing timing of ...
