Definitions

  • the invention relates to an exhaust gas recirculation device with a Jurrennan Aunt.
  • Exhaust gas recirculation devices are well known.
  • an exhaust gas outlet opening of an exhaust gas duct that can be closed by a valve body is arranged in such a way that exhaust gas generated by the internal combustion engine can be returned to the air intake duct and thus to the intake tracts of the individual cylinders of the internal combustion engine to reduce the amount of nitrogen oxide in the internal combustion engine.
  • a direct impact of the hot exhaust gas from the exhaust duct to the fresh air in the air intake duct can be used in conjunction with the settled on the channel walls of the air intake duct liquid such.
  • B. (Blowby, condensate, etc.) for the deposition of dirt particles such.
  • soot on the channel walls of the air intake duct or on the valve closing body which in turn may affect the function of the exhaust gas recirculation device.
  • the object of the invention is therefore to avoid the abovementioned disadvantage.
  • the flow guide is a substantially rectangular, bent sheet metal part with molded locking means, which are designed as locking lugs and as a ring insert. In this way, it is ensured that the media separating arrangement can be inserted in the simplest manner into the exhaust gas recirculation mixing housing, wherein the flow guiding body ensures that a mixing of the two media exhaust gas and fresh air takes place only far behind the valve closing member.
  • FIG. 1 shows a media separating arrangement 1 of the exhaust gas recirculation device according to the invention in a perspective view.
  • the media separation arrangement 1 consists essentially of a rectangular, bent sheet metal part 2 and locking lugs 3 and a ring insert 4, which as a locking means in such a way in wall portions 5 of an air intake duct 6 (see FIG. 2). engage until the media separating arrangement 1 is arranged in the air intake passage 6 so that it can not rotate or move.
  • FIG. 2 shows an exhaust gas recirculation device 7 with the media separating arrangement 1 which is inserted in the air intake channel by means of the latching means 3, 4 such that the flow guiding body 2 is arranged in the region of an outlet opening 8 of an exhaust gas channel.
