    • PROBLEM TO BE SOLVED: To provide an exhaust conduit for reducing complicatedness more than a conventional technology.SOLUTION: Each exhaust conduit (1, 1a, 1b, 1c and 1d) for an internal combustion engine includes a piping system (10) and at least one deformation compensating part (20) arranged in the extension in the longitudinal direction of the piping system for absorbing the deformation of the piping system (10). The piping system includes at least one cylinder connection part (40; 40a) arranged on the side of a wall (11) of the piping system for exhausting a cylinder of the internal combustion engine. The exhaust conduit for reducing the complicatedness more than the conventional technology. The exhaust conduit is particularly provided by mutually integrally forming the piping system and at least the one deformation compensating part.
    • 要解决的问题:提供一种排气管道,以减少比传统技术更复杂的排气管道。 解决方案:用于内燃机的每个排气管道(1,1a,1b,1c和1d)包括管道系统(10)和至少一个变形补偿部分(20),该变形补偿部分(20)沿纵向延伸 用于吸收管道系统(10)的变形的管道系统。 所述管道系统包括布置在所述管道系统的壁(11)侧的至少一个气缸连接部分(40; 40a),用于排出所述内燃机的气缸。 排气管道比传统技术更为复杂。 排气管道特别地通过相互整体地形成管道系统和至少一个变形补偿部件来设置。 版权所有(C)2012,JPO&INPIT

    • PROBLEM TO BE SOLVED: To avoid an environmental load caused by gas generated when spacer elements of a double wall pipe burn.SOLUTION: The double wall pipe (1) has an outer pipe (10) having an internal diameter (A) and an inner pipe (20) having an external diameter (I) and being arranged inside the internal diameter of the outer pipe, and thereby a tubular gap (ZR) is formed between the internal diameter of the outer pipe and the external diameter of the inner pipe. At least one curved position (30) is provided along the axial direction (AR) of the double wall pipe. At the curved position, spacer elements (40) filling the gap in the diameter direction are provided between the inner pipe and the outer pipe. Each spacer element fills only part of the gap in the axial direction. The double wall pipe avoids environmental contamination caused by removing each spacer element. This point is achieved especially because each spacer element is formed by metallic foam and thereby the element continues to remain in the gap.
    • 要解决的问题:为了避免双壁管的间隔件燃烧时产生的气体引起的环境负荷。 解决方案:双壁管(1)具有内径(A ID )的外管(10)和具有外径 (I AD ),并且布置在外管的内径的内侧,从而在外管的内径和外径之间形成管状间隙(ZR) 的内管。 沿双壁管的轴向(AR)设置至少一个弯曲位置(30)。 在弯曲位置,在内管和外管之间设置有沿直径方向填充间隙的间隔元件(40)。 每个间隔元件仅在轴向方向填充间隙的一部分。 双壁管道避免了通过拆卸每个间隔元件导致的环境污染。 这一点尤其是因为每个间隔元件由金属泡沫形成,从而元件继续留在间隙中。 版权所有(C)2012,JPO&INPIT
