摘要： A variable lift deactivateable valvetrain system for an engine is provided. The system includes a camshaft, a rocker shaft, a valve and at least one rocker arm rotateably connected to the rocker shaft and arranged to engage the camshaft. A connecting rocker arm is rotateably connected to the rocker shaft and is in constant engagement with the valve. The connecting rocker arm is arranged to operate in selective engagement with the at least one rocker arm to provide a variable lift deactivateable valvetrain configuration. The system further includes a low lift rocker arm having a low lift pin assembly and a high lift rocker arm having a high lift pin assembly. The low and high lift pin assemblies are arranged to selectively engage the connecting rocker arm responsive to oil pressure selectively directed to the low and high lift pin assemblies.

摘要： A rocker shaft arrangement for a valvetrain system of an engine is provided. The rocker shaft arrangement includes a split rocker shaft having two fluidly separate internal regions. Each of the fluidly separate internal regions is arranged to selectively carry an independent supply of pressurized oil for distribution to valvetrain components. The two fluidly separate regions of the split rocker shaft are each further arranged to supply pressurized oil independent of each other to one of a high lift rocker arm and a low lift rocker arm of a rocker arm assembly for an engine valvetrain system.

摘要： A position sensing system uses two sensing elements to sense the rotary position of target wheels mounted on two camshafts. The two sensing elements are mounted in a common sensor housing and preferably the two sensor elements share power and ground wires, and each sensor element has its own signal wire. The wires preferably are contained within a common conduit that extends from the housing to a location outside of the rocker cover. The end of the conduit may support one-half of an electrical connector that terminates the wires from the sensors. Mounting the two sensing elements in a common housing simplifies mounting the sensors on the engine, and reduces the number of wires required to power and derive signals from the two sensors. The target wheels are mounted directly on the camshafts and are positioned along the axis of the camshaft, spaced from the camshaft ends.
摘要翻译： 位置感测系统使用两个感测元件来感测安装在两个凸轮轴上的目标轮的旋转位置。 两个感测元件安装在公共传感器壳体中，并且优选地，两个传感器元件共享电力和接地线，并且每个传感器元件具有其自己的信号线。 电线优选地包含在从壳体延伸到摇臂盖外部的位置的公共导管内。 导管的端部可以支撑端接传感器的电线的电连接器的一半。 将两个感测元件安装在公共壳体中简化了将传感器安装在发动机上，并且减少了从两个传感器供电和导出信号所需的电线数量。 目标轮直接安装在凸轮轴上，并且沿着凸轮轴的轴线定位，与凸轮轴端部间隔开。
