Definitions

  • the invention relates to an exhaust manifold according to the preamble of claim 1.
  • Exhaust manifolds are used to divert exhaust gases from combustion chambers of an internal combustion engine in a common exhaust main or in a catalyst.
  • a further exhaust manifold of this type is known from DE 199 52 648 A1, in which the individual exhaust pipes and a shell surrounding them and the collecting pipe are welded to a fastening flange with which the exhaust manifold can be fastened to an engine block.
  • the present invention addresses the problem of providing an embodiment with simplified assembly for an exhaust manifold of the type mentioned.
  • the webs and the wall of the adapter are formed as a one-piece component, which eliminates additional fastening measures. In addition, thereby simplifies the assembly of the exhaust manifold.
  • this one-piece component may be formed as a stainless steel precision casting, which additionally increases the fatigue strength of the assembled exhaust manifold.
  • the transition from the Output ends of the exhaust pipes to the adapter are made particularly favorable.
  • a weld for attachment of the output ends is formed on the webs, this can be particularly easily prepared so that do not form in the flow cross-section protruding drips or noses. These measures reduce the flow resistance and the tendency to vortex formation, which improves the flow characteristics of the exhaust manifold.
  • such a weld can then be formed particularly uniform and homogeneous. The welds are then of high quality and have a correspondingly high
  • the webs in the flow direction, ie away from the output ends, upper project beyond the opening edge portions adjacent thereto, wherein a welded connection between the webs and the adjoining opening edge portions is formed in each case by a fillet weld.
  • a fillet weld can be especially be easily prepared, since there is a favorable burner position.
  • an exhaust manifold 1 has a plurality of exhaust pipes 2, which are provided on the input side with input ends, not shown here, for connection to an engine block of an internal combustion engine, where appropriate a suitable flange is arranged at the input ends.
  • the exhaust manifold 1 shown here is provided for four cylinders and therefore comprises four exhaust pipes 2, of which, for the sake of clarity, however, only three are shown.
  • a common adapter 4 which consists essentially of a circular cylindrical wall 5 and webs 6, which extend in the interior of the adapter 4 star-shaped to the wall 5.
  • the wall 5 is integral with the webs 6, in particular as a stainless steel investment casting produced.
  • four receptacles 7 are provided in the adapter 4, which are each formed between two adjacent webs 6 and extending between these webs 6 wall portion of the wall 5.
  • the receptacles 7 each have the shape of a quarter circle.
  • the output ends 3 In each of these recordings 7 one of the output ends 3 is plugged in, for which the output ends 3 are designed complementary to these recordings 7. Accordingly, the output ends 3 here also have a cross section in the form of a quarter circle.
  • the output ends 3 When inserted into the receptacles 7 output ends 3, the output ends 3 are arranged side by side in the adapter 4, wherein they are also completely covered by the wall 5 of the adapter 4.
  • the webs 6 are each arranged between two adjacent output ends 3, so that at each web 6 on each side of an output end 3 in the region of an adjoining opening edge portion 8 rests on the web 6. Due to the shape of the output ends 3 is also adjacent to the wall 5 opening edge portion 9 on the inside of the wall 5 at.
  • the exhaust pipes 2 are aligned in the region of their output ends 3 parallel to each other.
  • the exhaust pipes 2 extend in the region of their output ends 3 parallel to an outlet cross-section of the adapter 4, from which the exhaust gas transported from the exhaust manifold 1 enters into an exhaust main line, not shown, to be connected to the adapter 4. This means that the complete flow diversion takes place before the adapter 4, so that the Exhaust part flows of the exhaust pipes 2 in the outlet cross-section of the adapter 4 flow parallel to each other to unite to a common exhaust gas flow entering the exhaust main.
  • the receptacles 7 are adapted for the output ends 3 of the exhaust pipes 2 with respect to their inner contour in the corner relatively accurately to the outer contour of the output ends 3, so that no or only minor gaps or openings between the adapter 4 and the exhaust pipes inserted therein 2 train.
  • the adapter 4 may be equipped with a flange, not shown here, which may be e.g. attached to the wall 5, in particular made in one piece with this.
  • the exhaust pipes 2 are welded in the region of their output ends 3 to the webs 6 and to the wall 5 of the adapter 4.
  • a corresponding weld is designated 10 in FIG.
  • These welds 10 are in each case along the respective opening edge 11 completely encircling and thus executed closed, which on the one hand a high-quality connection of each individual exhaust pipe 2 is achieved to the adapter 4. On the other hand, this automatically results in a high-quality sealing of the plugged into the receptacle 7 output end 3 relative to the adapter. 4
  • the weld 10 can be particularly easily formed as a fillet weld. Such a fillet weld 10 can be easily produced with high quality, without affecting the flow-through cross sections occur.
