  • Publication number: 20070289954
    Abstract: In the method according to the invention for connecting a sheet metal component (3) to a component (5) consisting of cast metal, the sheet metal component (3) and the component (5) are welded to one another by means of a pulse-welding method. In particular, a sheet metal pipe (3) can thereby be welded to the port (12) of a housing (13) consisting of cast metal. This advantage may be utilized for an exhaust system with an exhaust manifold (3) and an exhaust assembly, such as a turbocharger (5).

  • Publication number: 20060013746
    Abstract: The invention relates to an exhaust system comprising exhaust pipes, through which hot gas flows and which are connected on the inlet side to a cylinder head of an internal combustion engine, and comprising at least one catalyst support element, attached to at least one exhaust pipe. To make it possible to use a catalyst support element close to the engine without affecting the engine compartment with respect to the available space, it is proposed that the catalyst support element exhibits a cross section that is largely identical to that of the exhaust pipes and forms, as a replacement, at least one section of an exhaust pipe.
