摘要： An electromechanical VVA system for controlling the poppet valves in the cylinder head of an internal combustion engine. The system varies valve lift, duration, and phasing in a dependent manner for one or more banks of engine valves. A rocker subassembly for each valve or valve pair is pivotably disposed on a control shaft between the camshaft and the roller finger follower. The control shaft may be displaced about a pivot axis outside the control shaft to change the angular relationship of the rocker subassembly to the camshaft, thus changing the valve opening, closing, and lift. A plurality of control shafts for controlling all valvetrains in an engine bank defines a control shaft assembly. The angular positions of the individual control shafts may be tuned to optimize the valve timing of each cylinder. The system is applicable to the intake and exhaust camshafts of diesel and gasoline engines.
摘要翻译：一种用于控制内燃机气缸盖中的提升阀的机电VVA系统。该系统以一个或多个发动机气门组为依赖方式改变气门升程，持续时间和相位。用于每个阀或阀对的摇杆子组件可枢转地设置在凸轮轴和滚筒指状随动件之间的控制轴上。控制轴可以围绕控制轴外部的枢转轴线移位，以改变摇臂组件与凸轮轴的角度关系，从而改变阀的开度，关闭和升程。用于控制发动机组中的所有阀门的多个控制轴限定了控制轴组件。可以调整各个控制轴的角位置以优化每个气缸的气门正时。该系统适用于柴油和汽油发动机的进气和排气凸轮轴。
