    • A marine outboard engine has an upper motor cover, a lower cover, an engine, a driveshaft, a gear case, a rotor shaft, and a bladed rotor. First and second exhaust housings are disposed in the lower cover below the engine. The second exhaust housing at least partially surrounds the first exhaust housing. A first exhaust chamber is formed by the first exhaust housing. The first exhaust chamber fluidly communicates with the engine. A second exhaust chamber is formed between the second exhaust housing and the first exhaust housing. The second exhaust chamber fluidly communicates with the first exhaust chamber. A third exhaust chamber formed between the second exhaust housing and the first exhaust housing below the second exhaust chamber is also disclosed. The third exhaust chamber fluidly communicates with the second exhaust chamber and an exterior of the marine outboard engine.
    • 船用舷外发动机具有上电机盖,下盖,发动机,驱动轴,齿轮箱,转子轴和叶片转子。 第一和第二排气罩设置在发动机下方的下盖中。 第二排气罩至少部分地围绕第一排气罩。 第一排气室由第一排气罩形成。 第一排气室与发动机流体连通。 第二排气室形成在第二排气室和第一排气室之间。 第二排气室与第一排气室流体连通。 还公开了在第二排气室和第二排气室下方的第一排气室之间形成的第三排气室。 第三排气室与第二排气室和船用舷外发动机的外部流体连通。

    • A personal watercraft includes a hull and an engine. The engine has an air intake system through which air is delivered to combustion chambers of the engine. An overturn switch detects overturn of the hull. A control device stops an operation of the engine based upon an output of the overturn switch. A throttle valve is disposed in the air intake system to be actuated by a throttle valve actuator. The control device controls the blocks the intake system based upon the output of the overturn switch to inhibit water from moving toward the combustion chambers. The control device allows the engine to be restarted during a preset period of time after stopping the engine operation.
    • 个人船舶包括船体和发动机。 发动机具有进气系统,通过该进气系统将空气输送到发动机的燃烧室。 翻转开关检测船体的翻倒。 控制装置基于翻转开关的输出停止发动机的操作。 节气门设置在进气系统中以由节流阀致动器致动。 控制装置基于翻转开关的输出来控制进气系统,以阻止水朝向燃烧室移动。 控制装置允许在停止发动机操作之后的预设时间段期间重新启动发动机。

    • An air intake assembly for a personal watercraft provides air to an internal combustion engine located within a hull cavity includes a housing having a generally horn-shaped configuration that includes a base and an outer end. The housing has an air passage that extends from a base to an outer end. An adaptor assembly connects the base to the hull and is arranged to form a seal around an opening in an upper portion of the hull. The adaptor assembly includes an opening aligned with the air passage. An air intake valve assembly is mounted in the opening with the valve assembly being arranged to be open to allow air flow into the hull when the upper portion of the housing points upward from a horizontal plane through the upper portion of the hull and being further arranged to close whenever the outer end of the housing has a downward pointing component.
    • 用于个人船只的进气组件为位于船体腔内部的内燃机提供空气,包括具有大致喇叭形构造的外壳,该外壳包括底座和外端。 壳体具有从基部延伸到外端的空气通道。 适配器组件将底座连接到船体,并且布置成围绕船体上部的开口形成密封。 适配器组件包括与空气通道对准的开口。 进气阀组件安装在开口中,阀组件被布置成敞开,以便当壳体的上部从水平面向上指向穿过船体的上部时进入船体,并进一步布置 每当外壳的外端具有向下指向的部件时就关闭。
