    Abstract: Systems and methods are provided for operating an internal combustion engine in a two-stroke mode or a four-stroke mode to achieve greater fuel efficiency and minimize emissions. The system comprises a mode-adaptable valve; a valve rocker arm to actuate opening and closing of the mode adaptable valve; a cam follower of a first cam for carrying out a two-stroke mode; a cam follower of a second cam for carrying out a four-stroke mode; and a pin to mechanically couple the valve rocker arm to the cam follower of the first cam or the cam follower of the second cam. Coupling the valve rocker arm to the cam follower of the first cam enables a two-stroke mode and coupling the valve rocker arm to the cam follower of the second cam enables a four-stroke mode.

    Abstract translation: 提供了用于以二冲程模式或四冲程模式操作内燃机以实现更高的燃料效率和最小化排放的系统和方法。 该系统包括可适应模式的阀; 阀门摇臂，用于启动模式适应阀的打开和关闭; 用于执行二冲程模式的第一凸轮的凸轮从动件; 用于执行四冲程模式的第二凸轮的凸轮从动件; 以及将阀摇臂机械地联接到第一凸轮的凸轮从动件或第二凸轮的凸轮从动件的销。 将阀门摇臂连接到第一凸轮的凸轮从动件，可以进行二冲程模式，并将阀门摇臂与第二凸轮的凸轮从动件联接起来，实现四冲程模式。
