More Information
Summary:A valve actuation mechanism is provided for hydraulically controlling cylinder deactivation and variable valve lift operation. The valve actuation mechanism includes a hydraulic circuit that is selectively pressurized to secure the reciprocating member in an extended position to transmit motion from the camshaft lobe to the intake or exhaust valve, and is bleed to allow the reciprocating member to reciprocate. 提供用于液压地控制停缸和可变气门升程操作的气门致动机构。所述气门致动机构包括液压回路，所述液压回路被选择性地加压以将往复构件固定在延伸位置中以将运动从凸轮轴凸角传递到进气门或排气门，并且被泄放以允许所述往复构件往复运动。
