    摘要： A vehicle exhaust system includes a subsystem having an exterior pipe formed of a polymer. A rigid liner extends along the length of the exterior pipe and defines a passageway. A fiber insulating layer is formed between the rigid liner and the exterior pipe. The liner is formed to define at least one groove circumscribing the periphery of the passageway. The groove defines a region of increased volume of the exhaust passage along the length. The liner is further formed to define at least one void extending between the wall of the liner and the insulating layer, around the periphery of the passageway. A plurality of apertures in the liner, allow sound waves to pass from the passageway into the fiber insulating layer, and into the void.

    摘要翻译： 车辆排气系统包括具有由聚合物形成的外部管的子系统。 刚性衬垫沿着外管的长度延伸并且限定通道。 在刚性衬套和外管之间形成纤维绝缘层。 衬套形成为限定围绕通道周边的至少一个凹槽。 该槽限定沿着该长度的排气通道的体积增加的区域。 该衬垫进一步形成为限定在该通道的周边周围延伸的至少一个在衬套的壁和绝缘层之间延伸的空隙。 衬垫中的多个孔允许声波从通道进入纤维绝缘层，并进入空隙。
