Definitions

  • the invention relates to an exhaust gas introduction device for an air intake duct system an internal combustion engine with an air intake duct housing, with a collective inlet, wherein the air intake duct housing consists essentially of an upper housing part and a lower housing part and the collective inlet with a Fresh air inlet channel cooperates, in which a throttle valve is arranged is and with an exhaust gas inlet arranged in the air intake system, which with an exhaust gas recirculation valve and an influencing the exhaust gas inlet jet Flow guide cooperates.
  • the flow guide ensures that the thermal Load for the exhaust gas recirculation valve is not too great and that the direct Impact of the hot exhaust gas from the exhaust duct on the fresh air in the Fresh air inlet duct no disadvantageous deposits of dirt particles, such as B. soot on the channel walls. Furthermore, the Flow guide body with a uniform mixing of the hot exhaust gas serve the fresh air.
  • the flow guide was used as an independent additional component, for example as a sheet metal part, inserted into the fresh air inlet duct, which causes a high assembly effort.
  • the invention is therefore based on the object above to avoid the disadvantage mentioned.
  • the upper housing part and / or the lower housing part have shaped elements which are in the assembled state of the air intake duct housing form the flow guide.
  • an exhaust gas introduction device for an air intake duct system created, which is particularly easy to assemble and thus characterized by low costs.
  • the flow guide body in the axial direction of the fresh air inlet duct extending annular shoulder defining an annular channel and through openings for the exhaust gas are provided in the annular shoulder are.
  • This configuration ensures particularly uniform mixing of hot exhaust gas and cool fresh air instead.
  • the air intake duct housing one of the housing parts has the exhaust gas inlet circumferential flange element and the annular shoulder, the annular channel in the axial direction by one adjoining the flange element Fresh air duct section is limited.
  • the upper housing part and the lower housing part can advantageously be produced by die casting.
  • FIG. 1 shows a schematic view of an exhaust gas introduction device 1 for an air intake duct system 2 an internal combustion engine, not shown.
  • the air intake duct system 2 essentially has an air intake duct housing 3 with a Collective inlet duct 4 (see FIG. 2, 3 or 4), the air intake duct housing essentially of an upper housing part 5 and a lower housing part 6 exists.
  • the collective inlet duct 4 is connected to a fresh air inlet duct 7, which in the present exemplary embodiment consists of a fresh air duct section 8 with a throttle valve 9 and a fresh air duct section 10, the Air intake duct housing 3 is formed.
  • the exhaust gas introduction device 1 consists essentially of an exhaust gas inlet arranged on the air inlet duct system 11 and an exhaust gas recirculation valve 12 which is connected to the exhaust gas inlet jet influencing flow guide body 13 (see FIG. 2, 3 or 4) cooperates.
  • Figure 2 shows a perspective sectional view of a first embodiment of the Exhaust gas introduction device according to the invention without exhaust gas recirculation valve.
  • the flow guide In this case, 13 is in the axial direction of the fresh air duct section 10 extending annular shoulder 13, which defines an annular channel 14, wherein in the annular paragraph 13 through openings 15 for introduction of the exhaust gas are provided.
  • the upper housing part 5 the exhaust gas inlet 11.
  • the upper part 5 of the annular shoulder 13 and a circumferential flange element 16 for connection integrally formed with the first fresh air inlet duct section 8.
  • FIG. 3 shows this exemplary embodiment of the exhaust gas introduction device in section, the fresh air duct section 8, which delimits the annular duct 14 in the axial direction, is shown.
  • the left arrow in Figure 3 shows the incoming fresh air and the upper arrow the inflowing exhaust gas.
  • Figure 4 now shows a second embodiment of the exhaust gas introduction device according to the invention on average.
  • the upper housing part has the exhaust gas inlet 11 and the circumferential one Flange element 16, which in the present case at the same time the annular channel 14th limited by the arranged in this case on the lower housing part 5 annular paragraph 13 is defined.
  • the exemplary embodiments mentioned are particularly simple to manufacture in the die casting process.
  • the mentioned formations are not based on the described embodiments must remain limited, it is also conceivable that in Figure 4 to produce the upper housing part shown with the annular shoulder, wherein then the exhaust gas inlet with the circumferential flange element on the lower housing part are trained.
