Definitions

  • the invention relates to an exhaust gas inlet device for a Lucasansaugkanalsystem an internal combustion engine with a Lucasansaugkanalgeophuse, with a collecting inlet, wherein the Heilansaugkanalgeophuse consists essentially of a housing upper part and a lower housing part and the collecting inlet cooperates with a fresh air inlet passage in which a throttle valve is arranged and arranged in the Beeransaugkanalsystem Exhaust inlet, which cooperates with an exhaust gas recirculation valve and a Abgaseinleitstrahl influencing Strömungsleit emotions, wherein the upper housing part and / or the lower housing part having form elements which form the flow guide in the assembled state of the Lucasansaugkanalgeophuses.
  • Exhaust inlet devices for air intake duct systems are well known.
  • Strömungsleit stresses ensures that the thermal load on the exhaust gas recirculation valve is not too large and that no adverse deposits of dirt particles, such as.
  • the flow guide should serve a uniform mixing of the hot exhaust gas with the fresh air.
  • the flow guide can, as described in the unpublished DE-A-100 32 149, as an independent additional component, for example, as a sheet metal part, are used in the fresh air inlet channel, which causes a high mounting effort.
  • the invention is therefore an object of the invention to avoid the above drawback.
  • the flow guide is an extending in the axial direction of the fresh air inlet channel annular shoulder, which defines an annular channel and wherein openings are provided in the ringfrömigen paragraph for the exhaust gas.
  • one of the housing parts has the exhaust gas inlet, a circumferential flange element and the annular shoulder, wherein the annular channel is delimited in the axial direction by a fresh air duct section adjoining the flange element.
  • one of the housing parts has the exhaust gas inlet and a circumferential flange element delimiting the annular channel, and the other housing part has the annular shoulder.
  • the upper housing part and the lower housing part can be advantageously produced by die casting.
  • the air intake duct system 2 essentially has an air intake duct housing 3 with a collecting intake duct 4 (see Figures 2, 3 or 4), wherein the air intake duct housing consists essentially of an upper housing part 5 and a lower housing part 6.
  • the collection inlet channel 4 is in communication with a fresh air inlet channel 7, which consists in the present embodiment of a fresh air duct section 8 with a throttle valve 9 and a fresh air duct section 10 which is integrally formed on the Lucasansaugkanalgephinuse 3.
  • the exhaust gas inlet device 1 consists essentially of an exhaust gas inlet 11 arranged on the air intake duct system and an exhaust gas recirculation valve 12 which cooperates with a flow guide body 13 influencing the exhaust gas inlet jet (see FIGS. 2, 3 or 4).
  • FIG 2 shows a perspective sectional view of a first embodiment of the Abgaseinleitvor Vietnamese invention without exhaust gas recirculation valve.
  • the flow guide 13 is in this case an extending in the axial direction of the fresh air passage portion 10 annular shoulder 13 which defines an annular channel 14, wherein in the annular shoulder 13 passage openings 15 are provided for introducing the exhaust gas.
  • a circumferential flange member 16 is integrally formed for connection to the first fresh air inlet passage section 8.
  • FIG. 3 shows this embodiment of the exhaust gas introduction device in section, wherein 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 incoming exhaust gas.
  • FIG. 4 shows a second embodiment of the Abgaseinleitvortechnische invention in section.
  • the effect of this Abgaseinleitvortechnisch remains the same, but the structural design is different.
  • the upper housing part of the exhaust gas inlet 11 and the circumferential flange member 16 which in the present case simultaneously limits the annular channel 14 which is defined by the arranged in this case on the lower housing part 6 annular shoulder 13.
  • the aforementioned embodiments are particularly easy to produce by die casting.
  • the said formations need not be limited to the described embodiments, it is also conceivable that the housing upper part shown in Figure 4 produce with the annular shoulder, in which case the exhaust inlet are formed with the peripheral flange on the housing base.
