Definitions

  • the present invention relates to an exhaust system of an internal combustion engine with at least one exhaust manifold with several inlet pipes for connection to exhaust gas outlets of the internal combustion engine and one Collecting device for summarizing the inlet pipes, the one Has outlet opening, which with subsequent elements of the exhaust system, in particular a catalyst housing is connected.
  • the exhaust gases emerging from the outlets of an internal combustion engine are usually via exhaust manifolds in one or more main exhaust pipes summarized.
  • the exhaust manifold has several for this Inlet pipes and a collecting device with an outlet opening, which with a further exhaust pipe or directly with a catalytic converter connected is.
  • the exhaust duct in the exhaust manifold has important for the exhaust gas back pressure.
  • One goal is the lambda sensor with the individual Exhaust gas flows from all inlet pipes flow as evenly as possible in order to to have the same conditions for each cylinder of the internal combustion engine.
  • the flow of a subsequent catalyst should be as possible be even.
  • the present invention has for its object an exhaust system to improve the type mentioned.
  • an advantageous Lambda and catalyst flow can be achieved.
  • the production should be as simple as possible and the stability of the exhaust system be as high as possible.
  • the collecting device as one-piece collector housing is made of rigid material.
  • the collection device By designing the collection device as a one-piece collector housing an advantageous construction of the rigid material Exhaust system can be reached.
  • the production can be simplified be because the one-piece collector housing, for example, by Hydroforming including necking for the pipe connection is inexpensive to manufacture and only simple Pipes are needed.
  • the collector housing has at least two, preferably three openings for connecting inlet pipes and an outlet opening through which the collector housing with subsequent Parts of the exhaust systems are connected.
  • the combination of a collector housing according to the invention is also advantageous made of rigid material with relatively flexible pipes, length compensation due to different thermal expansion enable.
  • the inlet pipes can be made relatively short be so that the collector housing is very close to the exhaust outlets of the Internal combustion engine can be introduced. This saves space and advantageously increases the exhaust gas temperature in a subsequent one Catalyst.
  • the collector housing is additionally has an opening for inserting a lambda probe.
  • the lambda sensor is therefore in a room in which the exhaust gas flows all inlet pipes of the exhaust system meet, so that one largely uniform flow to the lambda probe through the various Exhaust gas flows can be achieved.
  • the Redesign of the exhaust gas flow for the catalyst inflow after the Lambda probe take place, i.e. separately from the lambda flow. By this separation can optimize both inflows individually become.
  • the outlet opening an outlet pipe connected to the collector housing, which is designed in particular as a catalyst inflow pipe.
  • the outlet pipe fulfills a double function, and there can be a good inflow of catalyst can be achieved.
  • the catalyst inflow pipe is close to is guided in front of the catalyst, with the catalyst housing over a surrounding the catalyst inflow pipe, in particular funnel-shaped Tube is connected directly to the collector housing.
  • the openings in the collector housing are according to a further embodiment of the invention at least partially punched out. This allows the Manufacturing simplified and cheaper.
  • the inlet pipes open out in the collector housing such that the exhaust gas flow directions of all Flue gas flows converge at a collection point.
  • the exhaust gas flow is optimized.
  • the inlet pipes preferably open into the collector housing in such a way that the exhaust gas flow directions in each case opposite one perpendicular to the exhaust gas flow direction are inclined in the plane running in the outlet opening, in such a way that the exhaust gas flow directions of the inlet pipes face the same side of this plane as the exhaust gas flow direction in the Outlet.
  • the outflow of the exhaust gas through the outlet opening is thereby improved and the exhaust gas back pressure can be reduced.
  • a preferred arrangement of the lambda probe is on that of the outlet opening opposite side of the collector housing. For one thing, this can the arrangement of the probe tip at the collection point of the exhaust gas flows can be achieved well and on the other hand the exhaust gas flow becomes proportional little affected. In addition, this is structurally advantageous.
  • the inlet pipes open into the collector housing in particular in such a way that the collection point of the exhaust gas flows is inside the collector housing located.
  • the lambda flow occurs through this configuration within the collector's housing and before the realignment of the Exhaust gas flow for the catalyst outflow. Through this separation the flow to the lambda probe and the catalyst continues improved.
  • the collector housing preferably has molded connection pieces for the inlet pipes and / or the outlet pipe.
  • This configuration has on the one hand constructive advantages and on the other hand the assembly the exhaust system simplified. Above all, this configuration enables Welding the collector housing to the inlet pipes and the Outlet pipe on the outside. Penetration of sweat into it Interior of the exhaust system and the problems associated with it, in particular this can increase the risk of impairment of the catalytic converter be avoided.
  • the collector housing at least partially mirror-symmetrical to a plane that perpendicular to the connecting line of the exhaust gas outlets of the internal combustion engine runs.
  • the inlet pipes and / or the lambda probe are arranged in mirror symmetry and trained.
  • this allows the exhaust gas flow be made even more even.
  • this configuration the advantage that the components of the exhaust system are standardized can.
  • the same components can be used for different exhaust lines be used.
  • the internal combustion engine may be at least partially identical. This can save costs and simplify storage become.
  • the inlet pipes are preferably at least in sections with a oval cross section. This will make it more malleable the inlet pipes through which a better length compensation at different thermal expansion of the pipes can take place.
  • the exhaust system partially shown in Figures 1 and 2 includes two three-jet exhaust manifolds 1, 1 ', the inlet side with an engine flange 2, 2 'and on the outlet side via inlet funnels 3a, 3a' with a Catalyst housing 3, 3 'are connected.
  • To the catalytic converter housings 3, 3 ' each connects a further exhaust pipe 4, 4 ', which in turn each with a flange 5, 5 'for connection to a further one Exhaust pipe is connected.
  • the collector housing 9, 9 ' has walls into which Connection pieces 10, 10 ', 11, 11' and 12, 12 'are molded, and is from relatively rigid material formed.
  • FIGS. 3 to 6 enclose the walls of the collector housing 9, 9 'a collecting space 13, in which the exhaust gas flows out of the inlet pipes 6, 6 ', 7, 7', 8, 8 ' become.
  • the exhaust gas flow directions I, II, III are common Collection point 14 directed inside the collection room 13.

This will between the outlet pipe 21 and the inlet funnel 3a, 3a 'of the catalytic converter housing 3, 3' form an annular space 21a, which is connected to the exhaust gas flow as a shunt and as insulation acts for the exhaust gas flow.
  • the inlet pipes 6, 6 ', 7, 7' and 8, 8 ' are each welded with the collector housing 9, 9 'connected.
  • the weld seam is located in each case on the outside of the exhaust system, so no welding Contamination can get inside the exhaust system.
  • the inlet pipes 6, 6 ', 7, 7' and 8, 8 ' are each preferred by internal high pressure forming manufactured and exhibit in a medium range between their respective inlet ends and their respective outlet ends an oval cross-section.
  • This training with an oval cross section results in a relative high deformability of the inlet pipes 6, 6 ', 7, 7' and 8, 8 ', so that at Heating a length compensation can take place.
