Abstract
A continuously variable valve lift system includes a driving swing arm, a camshaft, a valve structure, a control shaft and an adjusting swing arm. The valve structure includes a roller rocker arm and a valve connected to the roller rocker arm. The driving swing arm has a driving arc surface. The driving arc surface contacts with the roller rocker arm to drive the valve to perform a reciprocating movement. The driving swing arm is sleeved on the control shaft and is capable of swinging around the control shaft. The control shaft is provided with a mounting part. The adjusting swing arm is connected to the mounting part and is capable of swinging relative to the mounting part. The adjusting swing arm is disposed between the camshaft and the driving swing arm. Two sides of the adjusting swing arm are contacted respectively with the camshaft and the driving swing arm.
