Definitions

  • the present invention relates to an air gap manifold for connecting exhaust gas outlet openings of an internal combustion engine, in particular motor vehicle engine, with an exhaust inlet opening of an exhaust system, with an inner part with a plurality of push-fit into each other exhaust ducts, a surrounding the inner part, gas-tight outer part and an existing between the inner part and outer part air gap.
  • An example of such an air gap bend is in EP 0 582 985 A shown.
  • the invention has for its object to provide an air gap bend of the type mentioned, on the one hand is low in the production and on the other hand allows compliance with the emissions regulations.
  • the exhaust ducts of the inner part are at least partially formed by shells, which are connected to each other by common edge-side forming, in particular folding.
  • the formation of the exhaust ducts of the inner part of shells is particularly inexpensive to manufacture.
  • the shells can be pulled cheaply.
  • Especially compared to welded joints results in a great cost advantage, especially when exhaust manifolds for turbocharger must be manufactured without welding spatter. Only expensive laser and TIG welding techniques can then be considered.
  • the forming compound of the shells according to the invention is for a sweat-spatter and on the other hand with little effort feasible.
  • the tightness of the forming connection between the shells is sufficient, since the outer shell of the manifold is absolutely gas-tight and therefore a small leakage of the inner part does not cause problems.
  • the thickness of the inner part can be kept relatively low, since no minimum thickness is required for the forming connection of the shells other than welding.
  • various types of steel for example, austenitic steel can be used.
  • the shells of the inner part may be provided with beads.
  • the shells of the outer part may have beads to increase the rigidity.
  • the shells of the outer part are preferably welded together.
  • the welded joints can be arranged on the outside, so that there is no risk of contamination of the interior of the exhaust manifold. It can also be used more cost-effective welding processes.
  • the inner shells can be locked by individual welds against each other. Since only a few spot welds are required to reliably prevent displacement, simple spot welds can be used without undue cost increase.
  • the shells can be embossed together.
  • the outer part preferably consists of two half-shells.
  • the exhaust passages of the inner part preferably each consist of two half-shells.
  • a particularly advantageous use of the air gap bend according to the invention is given in internal combustion engines with a turbocharger, since the manifold according to the invention can be made particularly inexpensive welding spatter free.
  • the preparation of the air-gap bend according to the invention is carried out such that first the one part of the exhaust ducts forming shells of the inner part are inserted into each other according to the desired sliding seat arrangement, then the respective other part of the exhaust ducts forming shells also, and then only the associated shells of the exhaust pipes together be joined together by pairs together edge formed, in particular folded.
  • the individual exhaust ducts are not first composed of, for example, two shells and then inserted the exhaust ducts formed in one another, but the nesting is done separately for each half of the inner part, and only then are the two halves of all exhaust ducts of the inner part connected to each other simultaneously.
  • the cross sections of the exhaust ducts in the sliding seat areas are adapted to each other.
  • the shells of the respective exhaust ducts are locked if necessary by welding points against each other. Then, the inner part is inserted into the shells of the outer part and these are connected in a gas-tight manner by welding.
  • the shells of the inner part are preferably made of sheet metal, in particular by deep drawing. Preferably beads are embossed in order to increase the rigidity of the shells.
  • two half shells are manufactured per exhaust guide, which are then connected to each other simultaneously with the other half shells.
  • the illustrated air gap manifold comprises an inner part 1 with a plurality of push-fit into each other inserted exhaust ducts 2, 3 and 4 and a surrounding the inner part 1 at a distance, gas-tight outer part 5. Between inner part 1 and outer part 5 is thereby formed an air gap 6, the heat insulation of Exhaust manifold causes.
  • the exhaust ducts 2, 3 and 4 are each formed of two half shells 2a and 2b, 3a and 3b, 4a and 4b, which are connected to one another at the edge.
  • the connection is a folded connection, as in Fig. 4 is shown.
  • the edge of one half-shell 3a is bent around the edge of the other half-shell 3b.
  • the exhaust ducts 2, 3 and 4 are, as I said, inserted into each other with sliding fit.
  • a falzoker area 8 is formed, to which the associated end 3 ", 4" of each adjacent Exhaust guide 2, 3 and 4 is arranged with sliding seat.
  • the other end 2 "of the exhaust gas guide 2 is connected in a gastight manner together with the outer shell 5 to a first inlet flange 9.
  • a second inlet flange 10 is gas-tightly connected to the outer shell 5 and the end 11 'of a lateral branch 11 of the exhaust gas guide 3.
  • Third and fourth inlet flanges 12, 13 are finally gas-tightly connected to the outer shell 5 and to a respective rigid sleeve 14, 14.
  • the sleeve 14 is seated in a lateral branch 15 of the exhaust gas guide 4 and the sleeve 14 'is also fitted with a sliding fit in the second end 4' Exhaust system 4.
  • the exhaust gas guide 4 has a second branch 16, in which a further sleeve 17 is inserted with sliding seat.
  • This sleeve 17 is connected in a gastight manner with an outlet flange 18 together with the outer part 5.
  • a continuing pipe of a conventional exhaust system can be connected. Accordingly, the inlet flanges 9, 10, 12 and 13 can be connected to exhaust gas outlet openings of an internal combustion engine.
  • the outer part 5 also has two half shells 5a, 5b.
  • the parting plane I of the half-shells 5a and 5b extends at an angle of approximately 90 ° to the parting plane II of the half-shells 2a, 2b, 3a, 3b, 4a and 4b of the inner part 1, and approximately parallel to the plane of the flanges 9, 10th , 12 and 13.
  • the production of the illustrated air-gap bend essentially takes place in such a way that firstly all half-shells 2a, 2b, 3a, 3b, 4a and 4b of the inner part 1 and 5a and 5b of the outer part 5 are produced.
  • beads 19 can be introduced into the half shells.
  • each one half shells 2a, 3a and 4a of the inner part 1 are inserted into each other according to the desired sliding seat arrangement.
  • the half-shells 2b, 3b and 4b of the inner part 1 are inserted into one another.
  • the sleeves 14 and 14 ' the nested shells 2a, 3a and 4a and 2b, 3b and 4b are inserted into a forming tool.
  • the inner part is finished and is used after removal from the forming tool in the lower shell 5b of the outer part 5. Together with this, the inner part 1 is then gas-tightly connected to the inlet flanges 9, 10, 12 and 13, in particular welded. Then, the sleeve 17 is welded gas-tight together with the upper shell 5a of the outer part 5 with the outlet flange 18. Subsequently, the upper shell 5a of the outer part 5 is placed on the lower shell 5b and welded gas-tight in the overlapping region.
  • the two half-shells 5a, 5b of the outer part 5 can be connected to each other by normal welding methods, since the weld is on the outside.
  • the illustrated and described embodiment of the inner part with sliding seats allows otherwise in a known manner a substantially unhindered thermal expansion of the exhaust ducts 2, 3 and 4 of the inner part 1, in particular a greater thermal expansion due to the greater heating of the inner part 1 relative to the outer part 5.
  • the outer part on the other hand ensures a high gas-tightness of the air-gap bend. In this way, a well-fit air-gap manifold can be produced at a relatively low cost.
