    • An exhaust system for a combustion engine which comprises at least one exhaust manifold with a plurality of inlet pipes for connection to exhaust ports of the combustion engine. The exhaust system comprises a collector device for merging of the inlet pipes, which has one outlet opening. The outlet opening is connected to subsequent elements of the exhaust system, such as catalytic converter housing. The catalytic converter inflow pipe is guided up to just before the catalytic converter; and the catalytic converter housing is connected directly to the collector housing via a pipe surrounding the catalytic converter inflow pipe. The collector device is made as a one-piece collector housing of a material stiff in bending.
    • 一种用于内燃机的排气系统,其包括具有多个用于连接到内燃机的排气口的入口管的至少一个排气歧管。 排气系统包括用于合流入口管的收集器装置,其具有一个出口开口。 出口开口连接到排气系统的后续元件,如催化转化器壳体。 催化转化器流入管被引导到催化转化器之前; 并且催化转化器壳体通过围绕催化转化器流入管的管道直接连接到集电器壳体。 收集器装置被制成具有刚性弯曲的材料的一体式收集器壳体。

    • A built-up airgap-insulated exhaust manifold of an exhaust system of a motor vehicle includes at least two exhaust pipes with an inlet flange attached in each case to one end and to be fastened to the cylinder head of an internal combustion engine of a motor vehicle. The exhaust pipes include a pipe bend and at least one branched pipe piece connected to the latter. If a plurality of branched pipe pieces are arranged they are connected to one another in a row and the last pipe piece in the row forms a header connected at one end to the exhaust tract leading further on in the exhaust system. The exhaust manifold has at least one exhaust pipe, which is designed as a double pipe with airgap insulation between an outer and an inner pipe, and possessing at least one exhaust pipe without an air insulation gap. The outer pipe and the inner pipe of the airgap-insulated exhaust pipe bear against one another at the end which is plugged together with and welded to an associated inlet flange.
    • 机动车辆的排气系统的积层气隙绝缘排气歧管包括至少两个排气管,每个排气管的入口凸缘在每个壳体中连接到一端并且被紧固到电动机的内燃机的气缸盖 车辆。 排气管包括管弯头和与后者相连的至少一个分支管件。 如果配置有多个分支的管件,则它们彼此连续连接,并且排中的最后一个管件形成在一端连接到排气系统中更进一步的排气道的集管。 排气歧管具有至少一个排气管,其被设计为在外管和内管之间具有气隙绝缘的双管,并且具有至少一个没有空气绝缘间隙的排气管。 空气绝缘排气管的外管和内管在端部彼此抵靠,其端部与一个相关联的入口法兰连接并焊接在一起。
