Definitions

  • the invention relates to an exhaust system of an internal combustion engine according to the preamble of claim 1 and a method for producing the collecting chamber of an exhaust system according to the preamble of patent claim 6.
  • Such an exhaust system of a Brennkratt engine is known from DE 40 24 801 A1, in which two exhaust pipes open approximately vertically into a collecting chamber arranged between two catalysts.
  • the collection chamber and the respective adjacent catalysts are formed in an oval-cylindrical metal housing.
  • No details are given in the cited publication on the detailed structure of the collecting chamber or the metal housing and on its manufacturing process.
  • two mainly used manufacturing methods for such a collecting chamber or a corresponding housing are known.
  • housings or collecting chambers are manufactured using the so-called internal high pressure forming process (IHU).
  • IHU internal high pressure forming process
  • the invention is based on the object to improve an exhaust system according to the preamble of the main claim to the effect that it has a simpler construction and is simpler, faster and more cost-effective to manufacture.
  • favorable cross-sectional profiles and connection methods are to be made possible, in particular in the inlet region of the exhaust pipes. 3ie are improved with regard to component rigidity, stress curve and permanent bending / vibration resistance.
  • the lateral surface of the collecting chamber is made from a wound sheet metal, which is closed with a longitudinal seam to form a hollow body, and the longitudinal seam runs at a distance from the entry point (s)
  • unfavorable seam profiles in the entry area of the exhaust pipes are avoided compared to the half-shell construction.
  • This also avoids structural changes in this area, so that overall a lower component rigidity and an improved fatigue strength or fatigue strength is achieved and smoother transitions at the entry points are possible.
  • the production is simplified or less expensive, since the comparatively short seam area means that much less welding effort is required.
  • connection of the exhaust pipes to the collecting chamber can be produced particularly easily and has a more favorable course with regard to the fatigue strength if circumferential edges which are drawn outwards are formed in the region of the entry points and which are connected to the outlet exhaust pipes. These peripheral edges can be formed from a preformed sheet metal element by a relatively simple forming process. Appropriate shaping ensures a transition between jacket and exhaust pipe which is favorable with regard to the bending strength or bending stiffness.
  • Fig. 1 is a schematically illustrated internal combustion engine and its exhaust system.
  • Fig. 2 is a partially shown view of this exhaust system, partially in

  • An internal combustion engine installed in a motor vehicle has - without limitation to this embodiment - two cylinder rows 1, 2 in a boxer arrangement.
  • Further manifold exhaust pipes 8 are connected to these nozzles and feed the exhaust gas from the cylinder banks 1, 2 to a housing 9.
  • This housing 9 extends at the rear of the internal combustion engine transversely to its longitudinal direction ? and has an approximately circular shape in cross section (FIG. 3).
  • the two collecting exhaust pipes 8 open into a collecting chamber 10 formed centrally in this housing 9, on the two end faces of which a catalyst 12 formed from two monoliths 11 is connected.
  • the collecting chamber 10 has a cylindrical jacket 17, which consists of a wound sheet metal and is enclosed on its front sides by the jacket 18 of the respectively adjacent catalyst 12 and a housing 19 encompassing it.
  • the front ends of the collecting chamber 10 or its jacket i7, the jacket 18 of the catalytic converter 12 and the further housing 19 are firmly connected to one another by a circumferential weld seam (not shown in more detail).
  • the jacket 17 of the collecting chamber 10 consists - as already mentioned above - of a flat sheet metal plate which is formed into a cylindrical tube by winding and welding on a longitudinal seam 20. Opposite the longitudinal seam 20, two inlet openings 21 are formed in the jacket 17, each of which is provided with a peripheral edge 22.
  • Monitoring regulations may require a separation of the exhaust lines of cylinder banks 1 and 2. It is possible to do this in the collection chamber 10 to use a partition 24, which consists of an approximately plate-shaped sheet metal and is inserted during assembly from one of the open end faces into the collecting chamber 10 and positioned and fastened between the two inlet openings 21.
  • the jacket 17 of the collecting chamber 10 consists - as previously mentioned - of a wound sheet.
  • the starting workpiece for the collecting chamber 10 or its jacket 17 is a flat sheet metal plate which is formed in several process steps.
  • the flat sheet metal blank which is cut to the intended dimensions, is bent in a U-shape in a first shaping step, the radius of curvature corresponding to the radius of the collecting chamber 10.
  • Domes or sockets pointing outward are drawn into the curved outer surface of the U-shaped intermediate piece by means of a stamp and a counterform.
  • these domes are pre-drilled in the area of their cover and then widened such that the walls run approximately parallel and their inside diameter corresponds to the outside diameter of the exhaust pipes 8.
  • the parallel legs of the U-shaped intermediate part are rolled up, so that a cylindrical shape is formed.
  • the two end faces of the wound sheet, which are now adjacent to one another, are joined together by welding in a longitudinal seam.
  • Other shapes of the weld seam are easily possible.
  • the longitudinal seam can be overlapping or with bent edges.
  • the exhaust pipes 8 are inserted into the inlet openings 21 with their peripheral edges 22 and connected to the jacket 17 by an annular seam.
  • the front ends of the collection chamber are connected to the jacket 18 of the catalysts 12 and the further housing 19. This is also done via a circumferential, ring-shaped weld.
  • the cross-sectional shape of the jacket 17 of the collecting chamber 10 is not limited to the circular cylinder shape described. It is easily possible for example, to form oval-cylindrical or also asymmetrically curved cross-sectional areas.
  • a correspondingly constructed collecting chamber can be arranged, into which, for example, two exhaust pipes open laterally (in the jacket) and one exhaust pipe open on the front.
