| 摘要 |
The present invention relates to a continuously variable valve lift comprising: a cam shaft (100) including a cam (110) on an outer circumference surface; a rocker arm (200) including a roller (210) corresponding to the cam (110) on an end, having the other end connected to a valve (220); a rocker arm bushing (201) inserted into the middle of the rocker arm (200) to be able to rotate; and a rocker arm shaft (202) placed in parallel to the cam shaft (100), and inserted into the rocker arm bushing (201). The opening degree of the valve is enabled to be varied by modifying the structures of the rocker arm shaft (202) and the rocker arm bushing (201) to optimize fuel efficiency and increase output, thereby improving marketability. |
