Definitions

  • the invention relates to an exhaust manifold for an internal combustion engine, the type specified in the preamble of claim 1.
  • an exhaust manifold for exhaust gas guidance from an internal combustion engine which consists of a multi-part inner shell and an outer shell surrounding it at a distance, and flange means for connecting the inner tube to a plurality of spaced-apart cylinder outlet channels of the internal combustion engine. Furthermore, an output flange is provided for connecting an exhaust pipe, which is attached to the inner shell.
  • the outer shell consists of shell parts which are connected to one another at their edges and encloses the inner shell at its ends led into the flange means. In this way, a space is formed between the inner shell and the outer shell, which can serve for air gap insulation or can be filled with an insulating material.
  • the flange means for all connections of the inner shell to the cylinder head are designed in the form of a continuous flange plate as a so-called composite flange, which is dimensionally stable and inelastic in relation to the much thinner sheet thicknesses of the inner shell and the outer shell. Therefore, the connection areas of the individual sections of the inner shell as Sliding seat can be designed so that the different strains caused by temperature changes can be compensated. To seal such sliding seat connections, additional sealing elements are provided which prevent the exhaust gas from escaping from the inner shell into the space between the outer shell and the inner shell. Such an arrangement is complicated in construction, expensive to manufacture and also has a high weight due to the composite flange.
  • DE-GM 80 04 882 describes an exhaust manifold which has four individual flanges lying in a row, the two middle individual flanges being connected to a first inner tube and the two outer individual flanges being connected to a second inner tube.
  • Each of these inner tubes has an outer shell, these outer shells each being composed of two shell parts connected to one another at their edges and enclosing the respective inner tube at its ends guided into the flange means.
  • a space for air gap insulation is formed between the inner tube and the outer shell.
  • the invention is based on the object of developing an exhaust manifold of the type mentioned in the preamble of claim 1 in such a way that a simple structure, a reduction in the total weight and a long service life are achieved.
  • a preferred embodiment of the subject matter of the invention is that lateral arches are connected to the straight section of the outer shell seam, the outer ends of which are connected to the inner tube.
  • the exhaust manifold can be designed such that the arc of the outer shell seam comprises a central section and sections adjoining it laterally, the radius of curvature of the central section being greater than the radius of curvature of the lateral sections.
  • the radius of curvature of the central section can be approximately five times the radius of curvature of the lateral sections.
  • the arch has a uniform curvature between its ends.
  • the radius of the arc should preferably be about 0.6 times the distance between the ends of the arc.
  • the outer shell is expediently formed from two half-shells which have a plurality of seams, of which the seams running between the input flanges are at a greater distance from the inner tube than the other seams. This creates a box construction, which results in a greater distance between the inner tube and outer shell in the areas that are adjacent to the inlet flanges.
  • the outer shell preferably has approximately the shape of a drop in a plane lying between the input flanges and running orthogonally to these.
  • a further embodiment consists in that the flange edge of one half shell is made wider than the flange edge of the other half shell, the protrusion of the wider flange edge preferably being 1 mm to 1.5 mm.
  • This shape of the flanged edges is particularly to be considered for certain joining methods, for example laser welding.
  • the push-in seam is formed from overlapping edges, the overlapping sections of which are preferably approximately 4 mm. All seams of the outer shell are welded.
  • at least one spacer preferably a spacer ring made of a material that burns without residue when heated, is provided between the inner tube and the outer shell.
  • an exhaust manifold 1 which essentially consists of an inner tube 2 carrying the exhaust gas and an outer shell 3, as well as a plurality of input flanges 10, 11, 12 and an output flange 5.
  • the inner tube 2 comprises an elbow piece 6, a T-shaped middle piece 7 and a Y-shaped connecting piece 8, each of the pieces 6, 7 and 8 being connected to one of the input flanges 10, 11, 12 and the connecting piece 8 having a connecting piece formed thereon 9 is fastened in the output flange 5 in the manner of a sliding seat.
  • the bend piece 6 has a connecting section 16 which is inserted into a sleeve section 17 of the middle piece 7 and is accommodated in the latter against the outside of the inner tube 2, possibly with little play.
  • a connection between the middle piece 7 and the connecting piece 8 is provided, specifically through a connecting section 16 ' on the middle piece 7 and a sleeve section 17 'on the connecting piece 8.
  • the outer shell 3 consists of a first half shell 14 and a second half shell 15, the edges of which lie at seams 18, 19, 20 and 21 and are welded together.
  • the first seam 18 extends between the input flanges 10 and 11, the second seam 19 between the input flanges 11 and 12, the third seam 20 follows the contour of the connecting piece 8 between the input flange 12 and the output flange 5 at a radial distance and the fourth seam 21 runs at a radial distance from the inner tube 2 from the input flange 10 to the output flange 5.
  • the first and second seams 18, 19 lie in a plane E near the flange plane, the course of the seams 18, 19 over a section 38 is at least approximately rectilinear and merge towards the input flanges 10, 11, 12 in an arc 13 with a large radius.
  • the respective outer ends 29 of the arches 13 form the connection to the pieces 6, 7, 8 of the inner tube 2, the distance between the ends 29 being designated by L.
  • rings 30, 30 ' On the inner tube 2 are two axially spaced rings 30, 30 ', which consist of a material that dissolves when heated accordingly.
  • polyethylene is considered as a material, which burns without residues and is not harmful to the environment.
  • FIG. 2 shows a section along the line II-II in FIG. 1, the illustration of the input flange and the end of the curved piece inserted into it being omitted for reasons of clarity.
  • the first half-shell 14 and the second half-shell 15 have outwardly curved edges 22, 22 'and 23, 23', on which the half-shells 14 and 15 lie mirror-symmetrically to each other.
  • the edges 22, 23 and 22 ', 23' are welded together and, due to the shape of the edges, the seams 18, 21 are formed as flared seams.
  • the seams of the outer shell 3, not shown in FIG. 2 have the form of flared seams.
  • the cross section of the outer shell 3 essentially has the shape of a drop, the first seam 18 running at a substantially greater distance from the curved piece 6 than the fourth seam 21.
  • the angle of wrap, over which the contour of the outer shell 3 is at a radially constant distance from the inner tube 6 runs, is preferably approximately 230 °.
  • 3 and 4 each show enlarged representations of the connection areas of the half-shells 14 and 15, from which the contour of the edges 22, 23 and 22 ', 23' and the shape of the flanged seam are clear.
  • the Width B of the flanged edges for mutual contact need only be small, a width B of approximately 1 mm is considered sufficient, but it can also be made larger due to the design.
  • an embodiment can also be provided in which the flange edge of one half shell is made wider than the flange edge of the other half shell, the protrusion of the wider flange edge preferably being 1 mm to 1.5 mm. This embodiment is particularly suitable for connecting the half-shells 14, 15 by means of laser welding.
  • FIG. 5 shows an embodiment variant of FIG. 1, in which the outer shell 3 is formed from two half-shells 24 and 25, the first seam 26 and second seam 27 of which run in an arc 28 of different curvature.
  • the shape is formed from a central section 35 with a large radius of curvature and laterally adjoining sections 36 with a slightly smaller radius, the outer end 34 of the sections 36 being welded to the ends of the curved piece 6 of the central piece 7 and the connecting piece 8 are passed into the openings of the input flanges 10, 11, 12.
  • the ends 34 of the arc 28 are thus also arranged at a distance L from one another.
  • the distance between the seams 26 and 27 from the inner tube 2 is not as large as in the exemplary embodiment in FIG. 1, but is still significantly larger than the distance between the seam 21 and the inner tube 2, as can be seen from the illustration in FIG. 6 emerges.
  • the embodiment of FIG. 5 corresponds to that of FIG. 1; this also applies to the reference symbols for identical parts.
  • FIG. 6 shows a section along the line VI-VI in FIG. 5, wherein, like in FIG. 2, shows a representation of the input flange and the inner tube section connected to it was waived.
  • the second seam 27 is designed as a plug seam, in which an edge 31 of the first half-shell 24 and an edge 32 of the second half-shell 25 interlock.
  • the shape of the fourth seam 21 corresponds to the flanged seam described in relation to FIG. 2.
  • the ring 30 ' is arranged between the inner tube 2 and the outer shell 3.
  • FIG. 7 shows an embodiment variant of FIG. 6, in which the fourth seam 33 opposite the second seam 27 is also designed as a plug seam, so that the edges of the half-shells 24 and 25 engage in the manner of a hat box.
  • Fig. 8 the detail VIII of Fig. 7 is shown enlarged, from which it can be seen that the overlapping edges 31 and 32 of the half-shells 24, 25 are connected to one another by a weld seam 37, an overlap section A being formed, which is preferably approx Is 4 mm.
  • FIG. 9 shows a further embodiment variant to FIG. 1, in which the contour of the first and second seams 39 and 40 corresponds to an arc 41 of uniform curvature, the ends 42 of which are fastened to the inner tube 2.
  • the radius of the arc 41 is approximately 0.6 times the distance L between the ends 42, the seams 39, 40 and the arc 41. Otherwise, this embodiment corresponds to that of FIG. 5, this also applies to the reference numerals for the same parts.
