Abstract
A cylinder deactivation system for a vehicle and a variable valve lift system is fabricated with an end pivot structure that can control two valves at the same time. The structure ensures reliability since a latching pin does not receive a shear force and provides an excellent assemblage and a cost reduction by minimizing the number of parts Such a cylinder deactivation system may include a rocker shaft having an oil supply hole, a rocker arm, a middle arm, and a latching portion separating the rocker arm from the middle arm when an oil pressure operates through the oil supply hole.
