    • PURPOSE: An apparatus is provided to attenuate noises by permitting the sound fields of exhaust noises generated from the double exhaust paths to be interfered with each other. CONSTITUTION: An apparatus comprises the first exhaust path(31) and the second exhaust path(32) extended in a horizontal direction and branched off from an exhaust manifold mounted to an engine; and mufflers(7A,7B) mounted to the lower portions of the first and second exhaust paths, respectively. One of the first and second exhaust paths is formed into a zig-zag shape, and connection members(37,39) which are communicated to apertures(33a,33b,35a,35b) of curved portions(33,35) of the zig-zag shape are coupled to the curved portions. The connection members operate by actuators(40) in such a manner that the connection members change their positions in a transverse direction.
    • 目的:通过允许从双排气路径产生的排气噪声的声场相互干扰,提供了一种衰减噪声的装置。 构成:装置包括沿水平方向延伸的第一排气路径(31)和第二排气路径(32),并从安装在发动机上的排气歧管分支; 和分别安装在第一和第二排气路径的下部的消音器(7A,7B)。 第一和第二排气路径中的一个形成为锯齿状,并且连接构件(37,39)与Zig的弯曲部分(33,35)的孔(33a,33b,35a,35b)连通 锯齿状结合到弯曲部分。 连接构件以致连接构件在横向上改变其位置的方式由致动器(40)操作。
