    • F01N13/16—Selection of particular materials

Definitions

  • the present invention relates to a silencer for the exhaust system of an internal combustion engine Motor vehicle, comprising a housing with a made from a two-layer sheet.
  • the housing shells of modern motor vehicle silencers are often made from a two-layer sheet manufactured, the individual layers of different Material. While the outer, for the mechanical strength designed position mostly a structural steel is used to manufacture the inner layer, exposed to the highly corrosive exhaust gas condensate is, stainless steel is used. Despite the one with the two-ply Structure of the housing shell associated effort such a design is still cheaper than the production of a functionally identical silencer with a single-layer casing made of stainless steel. This depends on the extreme price differences for stainless steel on the one hand and structural steel on the other together.
  • Spacers therefore ensure in particular Areas of strong curvature, as in typical oval Mufflers occur for the possibility of one Gas exchange between the two sheets.
  • the latter was particularly oval in cross-section due to the particularly firm contact of the inner sheet on the outer sheet in the areas of strong curvature the lower area in any case if in this Area neither in the inner sheet nor in the outer sheet a vent hole was intended to be hermetically sealed.
  • the at least one in the inner sheet or in that Outer plate provided vent hole in particular With regard to the salt water and condensate problem can be arranged in an optimized manner. Specifically, this means that with a suitable design of the silencer by the provided according to the invention by the spacers guaranteed air ring gap already one in the inner plate or arranged in the outer plate Vent hole is sufficient to remove gases from any Place between the two sheets by evaporating Manufacturing backlogs arise.
  • That vent hole can, if it is in the Outer sheet is provided on a splash proof Position be arranged; and becomes that vent hole provided in the inner panel, so it can in Area of the upper half of the silencer arranged be so that the penetration of condensate through that Vent hole between the inner panel and the outer panel is excluded.
  • a single vent hole is sufficient to allow the entire space between the inner sheet and the To ventilate the outer sheet, advantageously in that that the area through which in the case of the arrangement of the Vent hole in the outer panel splash water through get between the inner panel and the outer panel can, is minimal.
  • Spacers can be according to a preferred one Further development of the present invention in the form a surface structure of the inner sheet executed his. This is particularly cheap, but not at all mandatory. For example, the execution also comes the spacer in the form of a surface structure of the outer sheet. You can also do both Inner sheet like the outer sheet for producing corresponding Spacers have a suitable surface structure exhibit. Another way of realization the spacer provided according to the invention is between the inner sheet and the outer sheet insert an appropriately structured intermediate layer, for example in the form of a wire mesh. All these other options do not change anything the fact that from a manufacturing point of view Execution of the spacers in the form of a surface structure of the inner sheet proves to be particularly cheap.
  • the surface structure selective elevations of the inner sheet or of the outer sheet includes. This ensures comparatively large channels between the points of contact of the Inner sheet and the outer sheet through which evaporating residues get to the vent hole and can escape through it.
  • the amount of the above specified increases is particularly preferred between 0.5 times and twice the value the thickness of the sheet in question. Here are the increases particularly preferably evenly over that Distributed sheet. Your extension is chosen that it is particularly preferred between 2% and Make up 20% of the surface of the sheet in question.
  • the present can be particularly advantageous Realize the invention in such a silencer of the generic type, whose coat from a flat two-layer sheet metal blank is wound. Across from Half-shell mufflers come here Advantage of the full connection of the area between the two sheets through the continuous Air ring gap especially for wearing.
  • the silencer illustrated in the drawing includes a housing with a jacket 1 and two ends arranged end floors 2.
  • the interior 3 of the Muffler is through two partitions 4 in total divided into three functional chambers.
  • In the middle functional chamber open the upstream end floor and penetrating the neighboring partition Exhaust gas inflow pipe 5 and one on the outflow side End floor and the neighboring partition penetrating exhaust gas discharge pipe 6.
  • the silencer has an oval cross section.
  • the casing 1 of the housing is made of a flat, two-layer Sheet metal blank wrapped.
  • the outer sheet 7 is made relatively thick-walled; it is made of structural steel.
  • the inner sheet 8 is relatively thin-walled performed; it is made of stainless steel.
  • the inner sheet 8 has a surface structure in shape of arranged evenly distributed over the sheet punctiform knobs 9. Those pimples 9 that are about the thickness of the inner panel 8 to the outside raise the rest of the inner panel 10, form spacers 11, through which the inner panel 8 and the Outer sheet 7 to form an air ring gap 12 a defined distance from each other.
  • the air ring gap 12 surrounds the inner sheet 8 above it entire circumferential surface. It is over one in the inner panel 8 provided, in the upper vertex area arranged vent hole 13 in the interior 3 of the Muffler vented into it. Alternatively, there would be ventilation of the air ring gap 12 into the environment via a vent hole arranged in the outer plate 7 into consideration. It is understood that in the area of Front edges 14 of the silencer of the air ring gap 12 is tightly sealed by suitable measures, for example by flared seams, which the end floors 2 and the outer plate 7 of the housing shell 1 with each other connect.
