Definitions

  • the present invention relates to an exhaust system component of an exhaust system for an internal combustion engine, in particular of a motor vehicle.
  • Exhaust system components include, for example, mufflers, catalytic converters, particulate filters, SCR systems, NOX storage systems and any combinations thereof.
  • To reduce the fuel consumption of motor vehicles is trying to reduce the weight of the motor vehicle. This can be done, for example, by using light metals instead of ferrous metals and / or by using plastics instead of metals in order to produce components of the vehicle which are characterized by their low weight. Since plastics have a low temperature resistance to metals, the use of plastics in the area of an exhaust system is associated with great difficulties.
  • the present invention addresses the problem of finding a way for an exhaust system component to be able to at least partially produce it from plastic.
  • the invention is based on the general idea, in an exhaust system component, a component which is not acted upon directly by hot exhaust gases to produce from plastic and a metallic component, which is also not directly acted upon by the exhaust gas, to a metallic Component to fix, which can now be acted upon directly by the exhaust gas.
  • a component which is not acted upon directly by hot exhaust gases to produce from plastic and a metallic component, which is also not directly acted upon by the exhaust gas, to a metallic Component to fix, which can now be acted upon directly by the exhaust gas.
