    • An internal combustion engine includes a cylinder having a combustion chamber and an exhaust passage that can discharge gas from the combustion chamber, at least one valve body that is provided in the cylinder and can take an open state in which the combustion chamber and the exhaust passage communicate with each other and a closed state in which the combustion chamber and the exhaust passage are shut off, and a piston that reciprocatingly moves in the combustion chamber. The internal combustion engine can switch an operation cycle to two-cycle operation in which the piston reciprocates once and four-cycle operation in which the piston further reciprocates once in the open state of the valve body in addition to the two-cycle operation. The internal combustion engine includes detecting means for detecting a throttle opening or information concerning the throttle position and control means for controlling opening and closing timing when the valve body comes into the open state or the closed state. The control means controls the opening and closing timing on the basis of the information obtained by the detecting means, whereby the operation cycle is switched.
    • 内燃机包括:具有燃烧室和能够从燃烧室排出气体的排气通路的气缸;至少一个阀体,该至少一个阀体设置在气缸中并且可以处于打开状态,在该打开状态下,燃烧室和排气通道 以及在燃烧室和排气通道被关闭的关闭状态下相互连通,以及在燃烧室内往复运动的活塞。 内燃机除了二循环运转之外,还可以将运转周期切换为活塞往复一次的二循环运转和活塞在阀体的打开状态下进一步往复一次的四循环运转。 内燃机包括用于检测节气门开度或与节气门位置有关的信息的检测装置和用于在阀体进入打开状态或关闭状态时控制开启和关闭正时的控制装置。 控制装置基于由检测装置获得的信息来控制开启和关闭正时,由此切换操作周期。

    • A two-cycle engine having a cylinder (ll), an exhaust port (l5a) through the wall of the cylinder and an exhaust passage (l5) extending from the exhaust port with an exhaust timing control device located in the exhaust passage. The device includes a valve body l9 which, in a first embodiment, is pivotally mounted in the exhaust passage and extends to the exhaust port. In a second embodiment, the valve body (30) is fixed at one end and operates as a flexible resilient member to achieve variation in timing control. Each valve body is biased against a cam mechanism (26) which may be rotated to actuate the valve body for controlling exhaust timing. The cam also provides a sealing mechanism between the valve body and the upper surface of the exhaust passage.
    • 具有气缸(11),穿过气缸壁的排气口(15a)和从排气口延伸的排气通道(15)的双循环发动机具有位于排气通道中的排气正时控制装置。 该装置包括阀体19,其在第一实施例中枢转地安装在排气通道中并延伸到排气口。 在第二实施例中,阀体(30)固定在一端并作为柔性弹性构件操作以实现定时控制的变化。 每个阀体被偏置抵靠凸轮机构(26),凸轮机构(26)可旋转以驱动阀体以控制排气正时。 凸轮还在阀体和排气通道的上表面之间提供密封机构。
