    • An exhaust system of a motorcycle has exhaust pipe arrangement in which four exhaust pipes connected to front sides of cylinder heads of respective four cylinders of an engine with a pair of two cylinders being arranged in parallel with each other extend rearward of a motorcycle body by passing portions near an oil pan disposed below the engine, the respective two exhaust pipes are assembled in two sets of pipe assemblies by a pair of front side manifolds, respectively, and then, the two sets of pipe assemblies are assembled in one set of pipe assembly by another manifold disposed rearside of the paired manifolds, the one pipe assembly being connected to a silencer. The oil pan has a peripheral wall section constituting a side surface of the oil pan, the side surface has an inclination tapered downward the motorcycle body so as to provide substantially a V-shape in section substantially in parallel with bank angle lines of the motorcycle body, and the front side manifolds are disposed between a space defined by the inclined side surface of the oil pan and the bank angle lines of the motorcycle.
    • 摩托车的排气系统具有排气管装置,其中四个排气管连接到发动机的四个气缸的气缸盖的前侧,一对两个气缸彼此平行布置,通过传递向后延伸到摩托车主体的后方 在配置在发动机下方的油盘附近的部分,分别将两个排气管通过一对前侧歧管组装在两组管组件中,然后将两组管组件组装在一组管组件 通过设置在成对歧管的后方的另一个歧管,一个管道组件连接到消声器。 油盘具有构成油盘的侧面的周壁部,侧面具有向摩托车主体的下方倾斜的锥形,从而基本上平行于摩托车主体的横截面角线设置大致V字形 并且前侧歧管设置在由油底壳的倾斜侧表面和摩托车的倾斜角线所限定的空间之间。

    • In an exhaust system for a motorcycle with a V-type engine mounted thereon, the front cylinder exhaust line has a first exhaust pipe arranged to the front while the rear cylinder exhaust line has a second exhaust pipe arranged to the rear. The first and second mufflers are attached to one side of the vehicle body with the second muffler arranged in parallel to and above the first muffler and shifted behind with respect to the first muffler. The first expansion chamber of the first muffler and the first expansion chamber of the second muffler are connected to be in communication with each other by means of a communicating pipe. One end of the communicating pipe is joined to the peripheral surface of the muffler cylinder corresponding to the first expansion chamber of the first muffler while the other end is connected in parallel with the second exhaust pipe to the front-end entrance port of the second muffler corresponding to the first expansion chamber of the second muffler.
    • 在具有安装在其上的V型发动机的摩托车的排气系统中,前排气管线具有布置在前部的第一排气管,而后排气管线具有布置在后部的第二排气管。 第一和第二消声器被安装在车身的一侧,第二消音器平行于第一消声器并在第一消音器之上并相对于第一消声器向后移动。 第一消音器的第一膨胀室和第二消声器的第一膨胀室通过连通管连接成彼此连通。 连通管的一端与第一消音器的第一膨胀室对应的消音筒的周面接合,另一端与第二排气管并联连接到第二消音器的前端入口 对应于第二消音器的第一膨胀室。
