Definitions

  • the present invention relates to a trough-shaped exhaust gas collector for one Internal combustion engine with an exhaust manifold, one engine-side flange that has multiple cylinder outlets encloses, and an outlet flange Exhaust port. It also affects one Process for the production of such Exhaust collector.
  • the exhaust gas of several cylinders is generally known summarizing an internal combustion engine Exhaust manifold with several inlet pipes, one Pipe merging and an output pipe, the Inlet pipes each at an outlet of one Internal combustion engine are flanged.
  • Exhaust manifolds are either heavy castings that are used for operation at high temperatures, as in hot exhaust gases usually occur, suitable are.
  • an elaborate cutting Rework required to fit the mating surfaces to manufacture individual inlet pipe flanges.
  • Between The cylinder head and exhaust manifold flange is one additional seal required to blow off the To prevent exhaust gases.
  • the manufacture of such Castings are complex and especially for small ones Numbers expensive. The assembly is also time and expensive.
  • the European patent application EP 0718480 A1 discloses a generic trough-shaped Exhaust collector, the engine-side flange several Encloses cylinder outlets and their exhaust gases in a common tub to which one common outlet connector with an outlet flange connected. With such a device heat losses at low operating loads significantly decreased, causing a rapid increase in Temperature of a downstream catalyst and thus an improved efficiency of the same causes.
  • the second design is one made by deep drawing from sheet metal Exhaust gas collecting pan with a thick-walled engine side Welded flange. This inevitably happens too welding delay, which is a complex post-processing and the use of an additional seal required.
  • the object of the present invention is therefore a trough-shaped exhaust manifold at the beginning to create the type mentioned, which is inexpensive in the Manufacturing and easy at the same time Handling during assembly is.
  • the exhaust manifold and motor-side flange made of an integral sheet metal part, the motor-side mounting flange in one piece trained with the exhaust manifold and at the Edge is made by reshaping the sheet.
  • the sheet is heat-resistant deep-drawn stainless steel sheet, which for the Use at hot exhaust gas temperatures is suitable.
  • the sealing edge can, for example be designed in such a way that Flange level of the motor-side fastening and Sealing flange (in the following simplified as Sealing flange) protrudes and in assembled state sealing on the flange of the Cylinder head rests. This prevents the Sealing edge blowing off hot exhaust gases. Furthermore a sealing edge designed in this way looks like one Beading and increases the stiffness of the motor side Flange.
  • the present invention provides that a Loose flange plate on the motor side Mounting flange is attached. This will make one more even distribution of the contact pressure on the entire flange and thus on the seal guaranteed.
  • the loose flange plate itself then when the unit consists of the exhaust manifold and Motor-side flange made of a relatively thin sheet is produced, a deformation-free, tight system of the engine side flange on the cylinder head.
  • the possible reduction in wall thickness in this way of the sheet not only leads to a reduction in the Manufacturing costs and the weight of the exhaust manifold and for a favorable influence on the manufacturability; also becomes the heat storage capacity of the exhaust manifold reduced, which has a positive impact on efficiency a downstream exhaust gas cleaning system affects.
  • the loose flange plate can be circumferential, undivided be executed. For easier assembly, it can however, also advantageously carried out in a divided manner be.
  • the material thickness of such loose flange plates is 5 mm to 10 mm, preferably 8 mm, wherein simple structural steels can be used.
  • the Exhaust gas collecting pan with a wall thickness of 1.8 mm to 2.5 mm, preferably 2 mm. This will create a light construction with sufficient strength created.
  • the exhaust gas collecting pan can consist of one conventional single-layer sheet.
  • a preferred development of the invention stands out however, from the fact that the exhaust manifold - and according to the molded flange on the motor side - consists of a multi-layer sheet. This can be constructed in particular as a sandwich sheet, which two layers of sheet metal and in between a layer Has fiber fleece or the like.
  • the Exhaust manifold a substantially constant Has cross-section over the longitudinal extent. This causes the wall thickness of the sheet metal part after the Thermoforming over the entire length of the Exhaust manifold is essentially the same.
  • the outlet port in the direction of the longitudinal extent of the exhaust gas collecting pan is arranged at one end thereof.
  • the outlet port in the direction of the longitudinal extent of the exhaust gas collecting pan is arranged at one end thereof.
  • Another advantageous embodiment provides that in an internal combustion engine with exhaust gas recirculation (EGR) the exhaust gas recirculation duct from the exhaust manifold is enclosed.
  • EGR exhaust gas recirculation
  • a method of making the above Exhaust collector consists of the (mechanical or hydromechanical) deep drawing one originally flat sheet metal, creating a tub with it molded circumferential mounting flange and one Pipe approach (nozzle) is formed, the punching or cutting the flange contour and opening the Pipe approach and welding one Outlet pipe flange to the open pipe neck of the Exhaust collector.
  • the deep drawing can also be done several deep-drawing steps.
  • Beneficial Further developments of the method can be done during the Forming the formation of a sealing edge in the engine side mounting flange and forming provide an on-board area on this flange.
  • MAG welding offers a suitable welding process for the stainless steels used.
  • the through holes provided for the Flange fittings can be drilled or be punched out.
  • Another advantageous manufacturing process for Exhaust collector has one or more forming steps to form a trough-shaped structure with integrally connected to the motor side Mounting and sealing flange and one-sided arranged pipe approach. This is followed by a punch or Cutting process in which the outer contour of the Sealing flange and, if necessary, the holes for the Flange screw connection and the pipe neck punched out will.
  • a rotating or divided Loose flange plate is then preferably from 5 mm to 10 mm thick simple structural steel, the Outer contour and the position of the through holes with match those of the sealing flange. After if necessary, deburring and cleaning the loose flange plate is placed on the Sealing flange and welding one also deep-drawn outlet flange pipe.
  • Fig. 1 shows an exhaust manifold with a Exhaust manifold 1, one piece molded circumferential flange 2 and an outlet flange 3, which has a flange connection 15 with a molded on the exhaust manifold 1 Pipe attachment 4 is connected by a weld 6.
  • the motor-side flange 2 has in its Circumferential area set up Board area 5 on the strength of the same elevated.
  • the flange 2 is a sealing flange circumferential sealing edge (see. Fig. 4) executed what the use of an additional seal is unnecessary.
  • a loose flange plate 9 is on the flange 2 put on.
  • the one-piece, closed loose flange plate 9 before welding of the outlet flange 3 placed on flange 2.
  • the Extent of the exhaust manifold is one Much larger than its width and depth, what the design of the exhaust manifold for in-line and V-engines corresponds. With the latter, however, come two exhaust gas collectors with mirror-inverted arrangement Outlet flanges for use.
  • Fig. 2 shows the exhaust manifold acc. Fig. 1 from Direction of the outlet flange 3, the one triangular plan with three through holes 7 for fastening screws. Furthermore is the motor-side flange 2 shown, the Outer contour at the positions of the Through holes 8 for the flange screw connection Has projections. At the outer edge of the flange 2 is shown the rim area 5, the flange gives additional rigidity.
  • Fig. 3 shows a section along the line III-III from Fig. 2 by the exhaust manifold. It is next to the exhaust manifold 1 with the engine-side flange 2, the board area 5 and the weld 6 and the outlet flange 3 on the motor-side flange 2 placed loose flange plate 9 shown. In the Sectional view is also a the loose flange plate 9 and the flange 2 penetrating in alignment Through hole 8 recognizable for a flange screw.
  • the outlet flange 3 with the flange stub 15 is in this embodiment of the same material as the exhaust manifold 1 made, the Wall thickness of the exhaust manifold 1 by a few tenths Millimeters can be less. Width B and depth T the exhaust manifold 1 have approximately the same Magnitude.
  • Fig. 4 shows detail IV of Fig. 3, the Sealing edge 10 is shown by a distance t, which is approximately 0.5 mm, over the flange plane of the motor-side flange 2 protrudes.
  • This Projection fulfills a sealing function, which leads to an additional seal between the motor side Flange 2 and engine block can be dispensed with.
  • Fig. 5 shows a section through the exhaust manifold and the loose flange plate 9 in the assembled state to one Cylinder head 11 with the intake valve 12 and the Exhaust valve 13.
  • the operation of the Sealing edge 10 clearly on the flange of the Cylinder head rests sealingly. In this way the hot exhaust gases are blown out of the Outlet channel 14 avoided.
  • the exhaust manifold points in Comparison with the prior art with a cross section shallow depth, which means that the pipe socket with the Outlet flange 3 aerodynamically and not diagonally as in the prior art perpendicular to the outlet channel 14 is attached.
