    • An exhaust timing control apparatus for two-cycle engines of the type having one or more exhaust ports extending outwardly from the cylinder. A valve body is pivotally mounted within the exhaust passage in a recess specifically provided therefore. The valve has a control surface approaching the cylinder to define an apparent upper timing edge of the exhaust port. Holes are provided through the valve body for flow to operate to inhibit the build up of carbon deposits which often inhibit the operation of the valve. An inclined surface may be formed on the surface of the valve body to facilitate the removal of carbon. Edges may also be provided on the valve body which cooperate with the walls of the recess in the exhaust passage to knock off carbon build up such that it might be conveyed through the exhaust pipe and from the system.
    • 一种用于具有从气缸向外延伸的一个或多个排气口的类型的两冲程发动机的排气正时控制装置。 因此,阀主体可枢转地安装在排气通道内,因此具体设置在凹部内。 阀具有接近气缸的控制表面,以限定排气口的明显上限时间边缘。 通过阀体提供孔以用于流动以操作以抑制通常抑制阀的操作的碳沉积物的积聚。 可以在阀体的表面上形成倾斜表面以便于除去碳。 也可以在阀体上设置边缘,该阀体与排气通道中的凹槽的壁配合以将碳积聚起来,从而可以通过排气管和系统输送。
