Definitions

  • the present invention relates to a housing of an exhaust treatment component such as, for example, a catalytic converter, an adsorber, a filter, a particle trap. or the like, for use in an exhaust treatment installation, in particular such an installation in a motor vehicle.
  • an exhaust treatment component such as, for example, a catalytic converter, an adsorber, a filter, a particle trap. or the like, for use in an exhaust treatment installation, in particular such an installation in a motor vehicle.
  • housings of this type must, in particular, be suitable for having a predefined mechanical strength even up to temperatures of up to 800° C. and above, in order to ensure permanent fixing even when the exhaust treatment component is subjected to considerable dynamic loads.
  • a housing of an exhaust gas treatment component comprising a material having the following composition:
  • the nickel/aluminum-containing austenitic steel disclosed here has a relatively high nickel content.
  • This composition is particularly suitable for receiving metallic and brazed honeycomb bodies since these consist of a material similar to that of the brazed regions themselves, and an outstanding oxidation behavior is therefore achieved overall. This applies in particular when the metallic foils are joined together with a brazing material which results in a brazing region comprising approximately 70% nickel, 18% chromium and 10% silicon.
  • Intermetallic nickel-aluminum precipitations which greatly increase the mechanical strength properties at least up to temperatures of approximately 800° C., in particular compared with a simple austenitic steel material, occur precisely with the composition claimed, and the wall thickness of the converter shell can therefore be reduced. This possibility of reducing the wall thickness additionally makes it possible to provide housings of this type at lower cost and at lower weight, which are both very desirable.
  • the housing is used, in particular, for receiving a metallic honeycomb body which is brazed to the housing at high temperature.
  • the honeycomb body may be constructed with at least partially structured metallic foils, such that passages, through which the exhaust gas can flow, are formed. All the foils are preferably brazed (at both ends) to the housing on the circumferential side.
  • the sole FIGURE is a perspective view of a component of an exhaust gas treatment system.
  • an exhaust treatment component 6 comprising a housing 1 and a honeycomb body 5 , which is positioned in the interior 4 of the housing 1 .
  • the honeycomb body 5 is designed with a plurality of corrugated and smooth metal foils 7 which are stacked and wound together such as to form passages 8 through which the exhaust gas can flow.
  • An exhaust treatment component 6 of this type may be designed, in particular, as a catalyst support, a mixing element, an adsorber, a particle trap, or the like.
  • the housing 1 illustrated here with a cylindrical shape, has a length 3 and a thickness 2 .
  • the thickness 2 is advantageously in a range of less than 1 mm. In particular, it is less than 0.8 mm.
