摘要： A first exhaust chamber and a second exhaust chamber are disposed within a body of a watercraft. The first exhaust chamber communicates with an exhaust port of an engine through a first exhaust pipe. A first space of the first exhaust chamber communicates with the second exhaust chamber through a first inverted-U shaped pipe. The second exhaust chamber communicates with another space of the first exhaust chamber through a second inverted-U shaped pipe. The first and second inverted-U shaped pipes are each positioned in the flow path of the exhaust gas and bent to be substantially inverted-U shaped. The other space of the first exhaust chamber communicates with an outside of the body through a second exhaust pipe. An uppermost portion of the first inverted-U shaped pipe and an uppermost portion of the second inverted-U shaped pipe are located higher than a waterline of the watercraft.

摘要： Disclosed is a personal watercraft comprising an engine capable of achieving a high power without increasing the diameter of an output shaft where a crankshaft-side sprocket is attached, and thus without increasing the diameter of the sprocket. The engine is configured such that an extended shaft that is separable from the crankshaft and has a diameter smaller than that of the crankshaft is connected to one end portion of the crankshaft so as to be coaxial with the crankshaft, and a sprocket is provided on the extended shaft. With such a structure, by forming the extended shaft of a material having relatively high strength, the diameter of the extended shaft can be made smaller than that of the crankshaft, and hence, the diameter of the sprocket provided on the extended shaft can be reduced. Since the diameter of a camshaft-side sprocket can be reduced, the size of the entire engine can be reduced.
摘要翻译：公开了一种个人船舶，其包括能够实现高功率而不增加安装曲轴侧链轮的输出轴的直径的发动机，因此不增加链轮的直径。发动机构造成使得与曲轴分离并且具有小于曲轴的直径的延伸轴连接到曲轴的一个端部以与曲轴同轴，并且链轮设置在延长轴。通过这样的结构，通过形成具有相对高强度的材料的延伸轴，延伸轴的直径可以比曲轴的直径小，因此可以减小设置在延伸轴上的链轮的直径。由于可以减小凸轮轴侧链轮的直径，所以可以减小整个发动机的尺寸。
