Abstract: An exhaust line element includes an exhaust volume comprising a metal enclosure with a thickness smaller than 1 mm and at least one metal plate with a thickness comprised between 0.5 and 5 mm. The metal plate comprises a central part that does not contact the metal enclosure and between 2 and 4 fastening tabs are secured to the central part. Each fastening tab is spot and transparently welded to the metal enclosure.

Abstract: An exhaust gas system includes a first exhaust component and a second exhaust component that are spaced apart from each other by a solder gap that can be has great as 1.20 mm. A high temperature solder material is provided near the solder gap and is heated by an inductor to form an induction solder joint between the first and second exhaust components.

Abstract: A housing for a component of an exhaust system has an opening which is provided in the housing, and a pipe which is arranged in the opening and connected with the housing. The pipe projects out of the housing and is connected with a connecting pipe shortly behind the opening. The invention further relates to such a component.

Abstract: An exhaust gas collecting and cleaning device for a multi-cylinder engine comprising an exhaust-gas manifold (1) constructed as a casting and an exhaust-gas cleaning device (5) mounted near the engine, attached to the exhaust-gas manifold (1) and comprising a housing (6) and at least one exhaust-gas cleaning element (14) bedded therein. A tubular section (12), which is constructed as a sheet-metal part and projects from the casting, is cast into the exhaust-gas manifold (1) at the outlet end region thereof. To this there is joined a downstream segment of the housing (6) of the exhaust-gas cleaning device (5). According to an independent embodiment, a downstream exhaust-gas guide element (such as a corrugated pipe) instead of the exhaust-gas cleaning device is joined in corresponding manner to the exhaust-gas manifold constructed as a casting.
