凸轮轴 (8) 由曲轴的后齿轮系驱动。 凸轮轴的旋转需与曲轴的旋转精确正时。 该正时确保了保持活塞运动和气门运动之间的正确关系。
各气缸的凸轮轴中机加工有两个凸轮 (9)。 一个凸轮用于转动进气门的气门机构部件，另一个凸轮用于转动排气门的气门机构部件。
随着凸轮轴的旋转，气门挺柱 (7) 上的滚轮绕凸轮轴凸轮转动。 推杆 (6) 将该运动传递给摇臂 (4)。 摇臂随着摇臂轴组件 (5) 转动。 随着运动传递到气门桥组件 (3) 顶部，摇臂起着杠杆作用。 气门桥组件将运动从摇臂传递到气门杆顶部。 气门桥组件同时操作两个气门。 各气缸各有一对进气门和一对排气门。
旋转线圈 (2) 向气门启动旋转运动，使气门打开和关闭。 气门的转动使气门上的积碳保持在最低水平，这样就使气门使用寿命更长。
气门弹簧 (1) 用于为气门提供弹簧张力。 当挺柱绕凸轮轴凸轮转动一圈时，该力使气门关闭。
