Definitions

  • the main exhaust gas flow may have a positive effect even with regard to the flow conditions in the premixing area, by a suction effect generated by the main exhaust gas flow (negative pressure generation) in the premixing area a further directional influence of the liquid and / or the partial exhaust gas stream, out or parallel to the main injection direction is executable.
  • the passage opening may be formed as a completely circumferential annular gap.
  • the inner tube is connected via at least one web to the housing supporting and / or supporting. This at least one web is preferably arranged on the front side and within the bypass channel.
  • the Bypass passage is the area in which the partial exhaust gas flow passes from the passage opening into the radially inward premix area.
  • the web can furthermore have a geometry which allows a defined influencing of the exhaust gas part stream passing past it (eg its direction), for example the exhaust gas partial stream is deflected by the web and / or put into a twisting motion.
  • the partial exhaust gas flow undergoes a deflection by at least 10 °, preferably by at least 25 °.
  • it is advantageous if the webs are equidistantly spaced lying on a circular line and whose geometry is at least designed similar, so that a partial exhaust gas flow deflection over the circumference is similar executable.
  • a simple and cost-effective production of the mixing device can be achieved, for example, in that the housing, the inner tube, the guide element and / or the deflecting element are integrally formed in one piece, preferably a one-piece molded or in a melting process (eg laser sintering or laser melting) manufactured component ,
  • the housing 4 has a spiral-shaped housing section A, which extends at least partially around the inner tube 7. Due to the spiral shape, the exhaust gas 2 is supplied evenly around the circumference of the inner tube 7. At the end face 11 of the housing 4, the metering device 6 is arranged.
