Definitions

  • the present invention relates to an exhaust manifold for an internal combustion engine with at least one exhaust pipe, possibly one Exhaust pipe receiving outer shell and at least one with the Exhaust pipes and / or engine flange connected to the outer shell for connecting the exhaust manifold to the internal combustion engine.
  • Such exhaust manifolds have between the exhaust pipe and engine flange and if necessary between the outer shell and the motor flange and / or a welded connection between the outer shell and the exhaust pipe.
  • the problem occurs that foreign particles such as welding spatter in the exhaust manifold remain, the subsequent components such as later in operation Can damage catalysts and turbochargers.
  • To make this possible Avoid such exhaust manifolds with laser welded connections manufactured. But this is expensive and requires one relatively great effort for the exact manufacture of the interconnected Components.
  • the invention has for its object an exhaust manifold and a Specify processes for its manufacture that do not have these disadvantages exhibit. In particular, foreign particles in the manifold should be avoided become.
  • connection between the Exhaust pipes and the engine flanges and, if necessary, between the Exhaust pipes and the outer shell and / or between the outer shell and the motor flanges are designed as a soldered connection.
  • soldering process can be simplified and improved in that between the parts to be soldered together to a solder gap coordinated press fit is present. For one thing, this can make a close Soldering gap can be achieved, which leads to a relatively large distribution of the Lots leads.
  • the connection between the parts is not how when welding, linear but flat, which increases the strength is increased.
  • the parts to be soldered together thereby securely positioned until the soldering is complete.
  • fixation with tack weld spots and light Press fit to be provided.
  • the solder joints are arranged at a point protected from the exhaust gas flow.
  • the solder joints on a side facing away from the exhaust gas flow Side of the exhaust pipe or viewed in the exhaust gas flow direction behind one Paragraph should be arranged.
  • the solder joints are thereby in operation of the exhaust system are not directly flown by the exhaust gas flow and remain accordingly relatively cool. This makes it possible even at relative hot exhaust gases to use a solder joint on exhaust manifolds.
  • solder joints are in arranged a groove, the opening of which faces away from the exhaust gas flow.
  • the This enables solder joints to be better protected from the exhaust gas flow and be kept cool.
  • Such an embodiment is especially in engines with high exhaust gas temperatures such as gasoline engines advantageous.
  • Another way of closing the solder joints to the exhaust gas flow protect is the passage openings of the motor flanges for to design the exhaust gas flow in such a way that it flows in the direction of flow expand, and the exhaust pipes and / or the outer shell against to arrange the level encountered. This also simplifies assembly.
  • a particularly advantageous embodiment of the invention also results then when the motor flanges each around their passage openings have a groove in which the exhaust pipes and / or the outer shell the exhaust pipes are inserted.
  • the solder can do well are protected from exhaust gas and installation is particularly easy possible.
  • the outer shell of the exhaust manifold according to the invention is in known and advantageous way preferably from two half-shells. According to the invention, these two half-shells can also be used together be soldered. This means that a welding process and so that the formation of contamination is avoided. moreover the connections can be made in a single operation become.
  • the outlet flange of the exhaust manifold is also preferred with the Exhaust pipes and / or the outer shell soldered. As before, this will the formation of contaminants avoided and the simultaneous All connections can be made in one operation.
  • a copper solder with a melting temperature for example, can be used as the solder of approx. 1083 ° C, a copper-nickel solder with a melting temperature of 1085 ° C to 1100 ° C or a high-temperature nickel solder with a Melting temperature of approx. 1000 ° C can be used.
  • the parts to be soldered to each other are particularly important before soldering fixed against each other. This can simplify assembly and ensure tight and tight soldering.
  • the smallest possible solder gap is preferably set.
  • the inner component expanded at a solder point against the outer component be, for example by means of an expanding mandrel.
  • the solder gap is thereby preferably to less than 0.2 mm, in particular between approximately 0.02 and 0.015 mm set. These values have proven to be special for good soldering appropriately highlighted.
  • the soldering temperature is preferably between 1000 ° C and 1200 ° C, each according to lot.
  • a copper solder for example, it is between approx. 1100 ° C and 1150 ° C, with a copper-nickel solder approx. 1120 ° C and at a high temperature nickel solder approx. 1040 ° C.
  • the soldering is more common Way under a protective atmosphere, especially hydrogen, or in a vacuum carried out.
  • the exhaust manifold shown in FIG. 1 comprises three exhaust pipes 1, 2 and 3, each connected to a motor flange 4 at one end are.
  • the other ends of the exhaust pipes 1 and 2 are in one End of a manifold 5 inserted, the other end together with the other end of the third exhaust pipe 3 in one end of a another manifold 6 is inserted.
  • All exhaust pipes 1, 2 and 3 and the manifolds 5 and 6 are in one Outer shell 7 housed, which is formed by two half-shells 8 and 9 is.
  • the outer shell 7 is together with the exhaust pipes 1, 2 and 3 into the motor flanges 4 and together with the second manifold 6 in an outlet flange 10 is inserted. In the area of the outlet flange 10, however, only the outer shell 7 is firmly connected to the outlet flange 10, while the second manifold 6 is arranged cantilever.
  • the exhaust pipes 1, 2 and 3 are firmly connected to the engine flanges 4.
  • these have a gradation widening in the exhaust gas flow direction I. 11 so that a receptacle is formed in which the exhaust pipes 1, 2 and 3 are inserted together with the outer shell 7.
  • the exhaust gas openings 12 of the motor flanges 4 are each flush with the inner walls 21 of the exhaust pipes 1, 2 and 3 are formed.
  • solder connections between the exhaust pipes 1, 2 and 3 with the motor flanges 4 and the outer shell 7 in the area of the motor flanges 4 and the connection of the outer shell 7 with the outlet flange 10 and the connection between the two half-shells 8 and 9 the outer shell 7 are designed as solder connections.
  • a possible The type of soldered connection on the motor flanges 4 is in each case in FIGS. 2, 3 and 4.
  • solder 17 Through the sloping walls 13 and 15 and the arrangement of the outer shell 7 and the exhaust pipe 1 are two receiving areas 16 for solder 17 created, which can be used alternatively or cumulatively.
  • the solder 17 can be used as a paste be applied.
  • the soldered connection is then made by heating made, the solder 17 due to capillary action in the Gap 18 between the motor flange 4 and the outer shell 7 and in the gap 19 is drawn between the outer shell 7 and the exhaust pipe 1. Thereby creates a large-area connection that leads to a high durability leads.
  • the step 11 of the motor flange 4 just trained. That is, the wall 13 is perpendicular to Wall 14. Opposed by staggered arrangement of the exhaust pipe 1 the outer shell 7 can also have a receptacle 16 in this variant for lot 17 at level 11. The sloping wall 15 is here also trained smaller. Otherwise, the design is correct with the configuration of FIG. 2.
  • the motor flange 4 is in the area its exhaust passage opening 12 provided with a groove 20, the opening 22 points in the exhaust gas flow direction I.
  • the groove 20 are the exhaust pipe 1 and the outer shell 7 inserted, here the outer shell 7 opposite the exhaust pipe 1 is arranged offset, so that again a receptacle 16 for lot 17 is created.
  • Another shot 16 is here also through an inclined wall 15 following the wall 14 formed.
  • a solder ring is preferably used in this embodiment. The rest of the structure and the mode of action is again the same as for the Variant of Fig. 2nd
  • Such an exhaust manifold can be used in particular as a diesel manifold, because the exhaust gas temperatures are lower here.
  • Using a correspondingly higher melting solder is also the use possible with petrol engines.
  • a use of the solder joints is also due to the hidden arrangement of the solder joints by the Paragraph 11 or the groove 20 in the motor flange 4 reached.
  • One if possible low heating of the solder joint is also promoted by the fact that the Exhaust gas passage opening 12 of the engine flange 4 is flush with the inner wall 21 of the exhaust pipes 1, 2 and 3 is formed.
