Definitions
- the present invention relates to an air gap manifold for connection exhaust gas outlet openings of an internal combustion engine, in particular Motor vehicle engine, with an exhaust gas inlet opening of an exhaust system, with an inner part with several with sliding fit into one another Exhaust guides, a surrounding the inner part, gas-tight trained Outer part and an existing between the inner part and outer part Air gap.
- the invention has for its object to provide an air gap of the specify the type mentioned above, on the one hand low in the production and on the other hand allows compliance with the emission regulations.
- the formation of the exhaust ducts of the inner part of shells is special inexpensive in production. For one, the shells be pulled economically. On the other hand is the connection of the shells by common edge forming, in particular folding, particularly favorable in the production. Especially against welded joints There is a big cost advantage, especially if at 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-free and on the other hand with little effort feasible. The tightness of the forming connection between the shells is sufficient, because the outer shell of the manifold is completely gas-tight and therefore a slight leakage of the inner part does not cause problems leads.
- the sheet thickness of the inner part can be kept relatively low because of the forming compound the shells, unlike welding, do not require a minimum thickness is. This allows different types of steel, for example also be used austenitic steel.
- 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 by cheaper welding processes become.
- the inner shells In order to prevent a displacement of the shells of the inner part in use, can the inner shells by single welding points against each other be locked. Because only single welds are needed to one To prevent displacement safely, this can be simple spot welds be used without unduly increasing costs. Alternatively or additionally, the shells can be embossed together.
- the outer part preferably consists of two half-shells.
- the exhaust ducts 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 turbocharged internal combustion engines, as the inventive manifold particularly inexpensive sweat spatter can be made.
- the preparation of an air gap bend according to the invention takes place preferably such that first each one of the exhaust ducts forming shells of the inner part according to the desired sliding seat arrangement into each other, then each one the other Part of the exhaust ducts forming shells also, and then only the associated shells of the exhaust ducts together be joined by pairwise together edge deformed, in particular folded.
- the individual exhaust ducts are initially composed of, for example, two shells and then the thus formed exhaust ducts inserted into each other, but the nesting is done separately for each half of the inner part, and only then become the two halves of all exhaust ducts of the inner part simultaneously connected with each other.
- the cross sections of the exhaust ducts in the sliding seat areas together are adjusted.
- the shells of the inner part are preferably made of sheet metal, in particular by deep drawing. Preferably beads are embossed to to increase the rigidity of the shells.
- each exhaust system made two half-shells, which then simultaneously with the other Half shells are joined together.
- the illustrated air-gap manifold comprises an inner part 1 with several with sliding fit into one another plugged exhaust ducts 2, 3 and 4 and a surrounding the inner part 1 with distance, gas-tight Outer part 5. Between inner part 1 and outer part 5 is characterized Air gap 6 is formed, which is a thermal insulation of the exhaust manifold causes.
- the exhaust ducts 2, 3 and 4 are each composed of two half-shells 2a and 2b, 3a and 3b, 4a and 4b, which are connected to one another at the edge are.
- the connection is a folded connection, as they are in Fig. 4 is shown.
- the edge of a half-shell 3a is for this bent over the edge of the other half-shell 3b. Subsequently, the Fold 7, as shown by dashed lines, tilted to the strength of the Increase connection.
- the exhaust ducts 2, 3 and 4 are, as I said, with sliding fit into each other plugged.
- the fold ends 7 at one end 2 ', 3' of the Exhaust ducts 2 and 3 before the end of the respective exhaust duct 2, 3rd As a result, a falzoker area 8 is formed, to which the associated End 3 ", 4" of the adjacent exhaust system 2, 3 and 4 with sliding seat is arranged.
- the other end 2 "of the exhaust duct 2 is together with the outer shell 5 gas-tightly connected to a first inlet flange 9.
- a second Inlet flange 10 is gas-tight with the outer shell 5 and the end 11 'of a lateral branch 11 of the exhaust system 3 is connected.
- third and fourth inlet flanges 12, 13 are finally connected to the outer shell 5 and each a rigid sleeve 14, 14 'connected gas-tight.
- the sleeve 14 is seated with sliding seat in a lateral branch 15 of the exhaust system 4 and the sleeve 14 'also with sliding fit in the second end 4' of the exhaust system 4th
- the exhaust system 4 has a second branch 16, into which a another sleeve 17 is inserted with sliding seat.
- This sleeve 17 is together connected to the outer part 5 gas-tight with an outlet flange 18.
- a secondary pipe of a conventional Exhaust system can be connected. Accordingly, the inlet flanges 9, 10, 12 and 13 at exhaust outlet openings of an internal combustion engine connected.
- the outer part 5 also has two half shells 5a, 5b.
- the dividing plane I of the half-shells 5a and 5b extends at an angle of about 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, 10, 12th and 13.
- the production of the illustrated air-gap bend essentially takes place in such a way that first 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. There can be introduced into the half-shells beads 19. Then be each one half shells 2a, 3a and 4a of the inner part 1 accordingly the desired sliding seat assembly inserted into each other. Corresponding The half-shells 2b, 3b and 4b of the inner part 1 into each other plugged. After inserting the sleeves 14 and 14 'are in one another inserted half-shells 2a, 3a and 4a and 2b, 3b and 4b in a forming tool inserted.
- the inner part is finished and will after removal from the forming tool inserted into the lower shell 5b of the outer part 5. Together with this, the inner part 1 is then gas-tight with the inlet flanges 9, 10, 12 and 13 connected, in particular welded. Then the Sleeve 17 together with the upper shell 5a of the outer part 5 gas-tight with welded to the outlet flange 18. Subsequently, the upper shell 5a of the outer part 5 is placed on the lower shell 5b and in the overlapping area gas-tight welded.
- the two half-shells 5a, 5b of Outer part 5 can be joined together by normal welding methods be because 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 gas ducts 2, 3 and 4 of the Inner part 1, in particular a larger thermal expansion due to greater heating of the inner part 1 relative to the outer part 5.
- the Outer part 5 on the other hand ensures a high gas tightness of the Lucasspaltkrümmers. In this way can with relatively very low Cost a well-fit air gap manifold can be produced.
