Definitions

  • the present invention relates to a two-shell, air gap-insulated exhaust gas merging with at least two inlets and at least one outlet, at least an exhaust gas-carrying unit from an outer shell surrounded and each outlet of each exhaust gas-carrying unit fluidically with at least two inlets the relevant exhaust gas-carrying unit is connected.
  • Exhaust gas mergers of the type specified above are in a number of different designs known. What they have in common is that the double-shell, Air gap-insulated design prevents heat loss should be so that a downstream of the engine Catalytic emission control device if possible quickly after starting the engine, i.e. after one if possible short light-off time reaches their working temperature.
  • the present Invention the object of an exhaust gas merging to create the type specified at the beginning, which is particularly compact at low manufacturing costs Construction allows, the production of the exhaust gas Unit in thin-wall technology may be possible with the objective of a particularly quick start of the catalytic converter within a period less than 30 seconds after starting to enable the engine in question.
  • each of the exhaust gas Units comprises at least two pipe pieces, the one at each of its first ends has an inlet define and in the area of their opposite, the second ends lie flat against each other.
  • the above at least two pipe sections protrude with their second, abutting ends in a first opening of a Inner shell part, the at least one second, one Has outlet defining opening.
  • the said Inner shell part is assembled from two half shells. And in the area of their second, contiguous The ends are the at least two pieces of pipe mentioned in their longitudinal direction to each other and relative to the inner shell part slidable.
  • Exhaust gas merging is thus the mixed construction of at least one composed of at least three parts exhaust gas-carrying unit such that an out two half-shells joined together inner shell part at least two pieces of pipe that have their final shape especially when using the process of hydroforming can get connected.
  • each of the two pipe sections along its Longitudinal direction in the area of the relevant end relative to the inner shell part and relative to the other Pipe piece is displaceable, there is a particular compact, producible at comparatively low costs, functional design.
  • the heat capacity the exhaust gas-carrying unit can be minimized, since the exhaust gas-carrying unit due to the invention Design of the exhaust gas merging in Thin-wall technology (e.g. with a wall thickness of only 0.8 mm) can be produced.
  • a first preferred development of the invention is characterized in that the inner shell part a third opening defining another inlet having. In this way, particularly inexpensive 3-in-1, 6-in-1 and 6-in-2 exhaust mergers produce.
  • the spacer can in particular consist of such a material (e.g. PE) that it under the influence of, for example, heat, chemical Solvents or the like dissolves as this such is known from the prior art.
  • the spacer can be used, for example, as a spacer ring be executed, which on the assigned ends of the pipe pieces that are adjacent to one another are pushed on.
  • the annular spacer element is also conceivable by wrapping the associated ends of each other adjacent pipe pieces with a strip-shaped material manufacture.
  • spacer in that the assigned ends of the adjacent pipe sections in a given layer thickness with a spreadable, hardening compound coated or in a flowable hardening mass can be dipped.
  • Spacer can also be between the at least two pipe pieces lying flat against one another during the Assembly of the exhaust gas-carrying unit correspondingly flat Spacer plates are inserted with regard to their Material is the same as for the annular spacer.
  • Yet another preferred development of the invention is characterized in that both the pipe pieces and the inner shell part each have a flow deflection of about 90 °, describing the level the flow deflection of the inner shell part essentially stands vertically on the level of the flow deflection of the pipe pieces.
  • the particular advantage of this Further training lies in the particularly compact Design of the exhaust gas junction.
  • Exhaust gas mergers e.g. 4-in-1, 4-in-2, 6-in-1, 6-in-2).
  • Exhaust gas combination marked essentially by two in a common outer shell Exhaust gas leading arranged in mirror symmetry to each other Units, their respective outlets to each other in a common outlet opening of the outer shell lead.
  • the exhaust gas merging designed as a 6-in-1 or 6-in-2 elbow, see above have the two inner shell parts particularly preferred each a third, defining a further inlet Opening up, with these two inlets in particular can be connected to a common flange plate.
  • the common flange plate helps that the two inner shell parts their predetermined position adhere to each other.
  • the Outer shell of the exhaust manifold As for the outer shell of the exhaust manifold according to the invention, As for another one Development of the invention characterized in that the Outer shell is composed of two half shells, the dividing plane transverse to the direction of flow runs in the area of the inlets. This is particularly so in terms of ease of installation and Manufacturing costs are particularly low since the two Half shells using a single, uninterrupted Weld seam can be connected to each other.
  • One of the two half-shells has one of the numbers number of inlet openings corresponding to the inlets through which the pipe pieces with their first ends and possibly the one on the at least one inner shell part step through the molded inlet. Is particularly cheap if, in the case of the double mentioned above, spatial flow deflection the division plane the outer shell runs through the common outlet opening.
  • the present invention not limited to such exhaust gas mergers is, in which all pipe sections of an exhaust gas Unity from the same direction and through the same Open the opening in the inner shell part. Rather comes within the scope of the present invention, that, for example, two pairs of pipe pieces from opposite directions and through different Openings in a single, common inner shell part open, with a common on that inner shell part Outlet can be molded. In this case too, namely for the production of a 5-in-1 or 6-in-1 exhaust gas junction to the inner shell part or two inlets.
  • the exhaust gas junction shown in the drawing comprises an outer shell 1 and two as main assemblies contained therein while maintaining an air gap exhaust gas-carrying units 2 and 3.
  • the outer shell 1 is composed of two half shells 4 and 5.
  • the exhaust gas-carrying unit 2 is assembled from the inner shell part 6 and the two Pipe pieces 7 and 8, the inner shell part 6 in turn assembled from the two half-shells 9 and 10 is.
  • At the half-shell 10 there is an inlet 11 formed.
  • Two further inlets 12 and 13 of the exhaust gas Unit 2 are formed by one each first end of the two pipe sections 7 and 8.
  • inlets 12 and 13 defining ends are opposite ends Pipe pieces 7 and 8 shaped D-shaped; here are the two pipe sections 7 and 8 flat back to back to each other on (see Fig. 5).
  • the two pipe sections 7 and 8 project together into an opening 14 of the inner shell part 6, in such a way that the two Pipe pieces along their longitudinal axis in this area relative to each other and relative to the inner shell part 6 can move.
  • Points in the area of the opening 14 the inner shell part 6 a substantially oval Cross section on; the parting plane 15 of the inner shell part 6 is guided so that the two half-shells 9 and 10 in the area of the flat sides of the inner shell part are put together.
  • Another opening 15 of the inner shell part 6 defines the common Outlet of the exhaust gas-carrying unit 2, through which that entering through the three inlets 11, 12 and 13 Exhaust leaves this exhaust-carrying unit again.
  • the second exhaust gas-carrying unit 3 is essentially constructed in the same way as the exhaust gas-carrying unit 2, so the above explanations also for this be valid. It should only be noted that in one of the Pieces of pipe protrude 17, on which one Exhaust gas recirculation can be connected.
  • the outlet 18 of the second exhaust gas-carrying unit 3 D-shaped shaped (see Fig. 6).
  • the two outlets 16 and 18 lie flat against each other back to back and are both via the common outlet 19 of the outer shell 1 connected to the outlet flange 20.
  • the outer shell 1 it is characteristic that the Parting plane 21 along which the two half-shells 4 and 5 are joined together, not in the direction of flow level defined in the area of the inlets lies, but rather across this. Accordingly points the half-shell 5 of the outer shell 1 six short inlet connections 22 on which the six inlets of the two exhaust-gas-carrying units 2 and 3 lie on the inside.
  • the outlet runs the parting plane 21 due to the specific Geometry of the exhaust gas merging, which is through a double flow deflection by 90 ° each distinguished, through the outlet 19.
