CONTINUOUS VARIABLE VALVE LIFT APPARATUS

摘要

PURPOSE: A continuously variable valve lift apparatus is provided to enhance the engine performance since a valve lift apparatus advances in change of a high lift apparatus to a low lift apparatus. CONSTITUTION: A continuously variable valve lift apparatus comprises a driving shaft(10), an input cam(20), a first shaft(30), a locker arm(40), an output cam(50), a valve opening/closing unit(60) and a control unit. The input cam is off-centered from the driving shaft. The first shaft is installed in parallel to the driving shaft. The locker arm is connected to the first shaft. The locker arm moves around the pivot according to the rotation of the input cam. The output cam rotates around the driving shaft. The valve opening/closing unit is opened/closed in a state of making contact with the output cam. The control unit is installed so that the relative position of the pivot to the driving shaft is varied.
