Definitions

  • the invention has for its object to provide a simple, inexpensive to manufacture and yet allow the steady flow to the lambda sensor flange connection.
  • the manufacture of the upper part as a deep-drawn sheet metal part not only has the advantage of simple manufacture, but also the further advantage that the temperatures transmitted by the header pipes and the thermal expansions resulting therefrom are reduced via the soft drawn part. Since an air gap arises when the upper part is joined to the sealing plate, this results in an insulating effect in which the thermal bridge is far less than in the case of a solid flange. This leads to a thermal relief of the flange connection between the exhaust manifold and the further component, in particular a front pipe.
  • the upper part can, according to the invention, face away from the sealing plate and surround its opening for the header pipe Show necking.
  • the manifold can be attached to this neck, in particular welded with a circumferential weld seam.
  • the header pipe is only fastened to the upper part with an axial distance from its end edge to the sealing plate. Due to the axial spacing of the end edge, the gas flowing through can reach the lambda probe radially laterally through the connection provided. It is therefore not necessary to use a collector pipe with a side opening.
  • the upper part can have a tunnel-like configuration leading from the opening for the collecting tube to the connection for the lambda probe.
  • a connection can be made with a directed, defined flow.
  • the tunnel-like shape can be produced very easily in the manufacture of the upper part as a deep-drawn part without an additional work step.
  • the flange can have two openings for attaching two manifolds, in which case the connection for the lambda sensor is connected to both openings.
  • the lambda sensor can then take into account the exhaust gas behavior of the cylinders of the internal combustion engine leading to both manifolds.
  • connection for the lambda probe is arranged and formed symmetrically to the two openings for the header pipes. This ensures that both manifolds are evenly separated from the lambda sensor be checked so that a real averaging of the exhaust gas behavior is carried out.
  • the invention also proposes that the connections between the openings for the header pipes and the lambda probe can have the same flow resistance.
  • the upper part can be welded to the sealing plate, in particular by means of a circumferential weld seam.
  • the upper part can at least partially lie flat against the sealing plate, in particular in its edge region.
  • Fig. 1 shows a simplified view of part of the flange connection, namely that of the sealing plate placed top part 1.
  • the top part 1 just like the sealing plate 2 underneath, contains two openings 3 of equal size lying next to one another with a circular shape.
  • Each opening 3 is intended for the attachment of a header pipe which is to be connected to a corresponding further component, for example a double-flow front pipe.
  • the upper part contains a third opening 4, which also has a circular shape, but has a different size in the example shown. This opening forms a connection 5 for a lambda probe.
  • the opening 4 is arranged symmetrically to the two openings 3 for the header pipes, that is to say that the center point of the connection 5 for the lambda probe lies on the perpendicular to the middle between the two openings for the header pipes.
  • a tunnel-like connection 6 leads laterally from each opening 3 for a collecting tube approximately radially to the opening 4 for the lambda probe.
  • These connections 6 are designed as protrusions emerging from the surface of the upper part. Both connections 6 have the same length and the same cross-sectional shape, so that they also have the same flow resistance for a flowing gas.
  • FIG. 2 represents a cross section along line II-II in FIG. 1.
  • the cross section is such that it leads through the center points of the opening 3 and the opening 4 and thus also through the longitudinal center plane of the one connection 6.
  • Fig. 2 shows the upper part 1 in the same state as Fig. 1, that is placed in the correct position on the sealing plate 2, possibly already attached.
  • the sealing plate 3 contains two openings 7 corresponding to the openings 3, which are aligned with the openings 3.
  • the openings 3 of the upper part 1 are formed by neckings 8 which protrude from the sealing plate 2.
  • the neckings 8 form short cylindrical lugs into which the collecting tube 9 can be inserted a short distance.
  • the connection of the collecting tube 9 with the neck 8 is done by a circumferential weld.
  • the collecting tube 9 is only inserted into the neck 8 to such an extent that the end edge 10 of the collecting tube maintains a distance from the upper side of the sealing plate 2.
  • the upper part 1 also has a distance from the sealing plate in the area surrounding the opening 4, similar to the area of the connection 6.
  • the cross section of the transition 11 is approximately quarter-arch. Connection 6 opens into this area.
  • a nozzle 12 is inserted, which is shown in Fig. 2 slightly above the opening 4.
  • the nozzle 12 can be a turned part or an extruded part.
  • This connector 12 contains a thread on its side, not shown, facing away from the upper part 1, so that a commercially available lambda probe is screwed in can be.
  • the connection of the connecting piece 12 to the upper part also takes place in such a way that the end edge 13 is at a distance from the sealing plate 2. Again, a weld seam along the circumference of the socket 12 can be used to connect it to the upper part 1.
  • the flange thus formed which is arranged at the end of an exhaust manifold, can then be connected to the further front pipe, for example by screwing using the stud bolts 14. Wedging would also be possible.
