    • A multi-mode valve control mechanism for an engine includes a primary cam follower rotatably mounted within a mount and having one end engaging a camshaft. One or more secondary cam followers are rotatably mounted within the mount and having one end engaging the camshaft. Each secondary cam follower is operatively coupled to a shaft. A follower is dedicated to each cam lobe. A frequency and a duration at which valves in a valve train are actuated is changed by activating only the primary cam follower in a first mode of operation, or activating both the primary cam follower and the one more than one secondary cam followers in a second mode of operation, depending on whether the control mechanism has been activated or not. In either mode of operation, the entire valve train assembly is actuated.
    • 用于发动机的多模式阀控制机构包括可旋转地安装在安装件内并具有与凸轮轴接合的一端的主凸轮从动件。 一个或多个次级凸轮从动件可旋转地安装在安装件内并具有与凸轮轴接合的一端。 每个次级凸轮从动件可操作地联接到轴上。 跟随者专用于每个凸轮凸角。 通过在第一操作模式下仅启动主凸轮从动件或者以第二模式激活主凸轮从动件和多于一个的次级凸轮从动件来改变阀系中的阀被致动的频率和持续时间 的操作,取决于控制机构是否已被激活。 在任一操作模式下,整个气门机构组件被致动。
