-16. (canceled)
A evaporation and gas mixing device for an exhaust gas after-treatment system, the device is for mixing an exhaust gas stream from the exhaust gas after-treatment system with an evaporated reductant, the device comprising:
- a) a housing having an upstream inlet for receiving the exhaust gas stream and a downstream outlet for distributing the exhaust gas stream after mixing with the evaporated reductant,
- b) a mixing chamber located inside the housing for swirling the exhaust gas stream and evaporated reductant for mixing inside the chamber having at least one opening for introducing the reductant into the mixing chamber and having at least two separate inlets for receiving the exhaust gas stream and at least one outlet in communication with the downstream outlet of the housing for distributing the exhaust gas stream after mixing with the evaporated reductant,
- c) a dosing module for introducing the reductant through the at least one opening into the mixing chamber for evaporation and mixing with the exhaust gas stream, wherein the dosing module is arranged at one end of the mixing chamber opposite the at least one outlet of the mixing chamber,
- d) a first guiding means located inside the housing having at least one inlet adapted to receive and guide the exhaust gas stream to the mixing chamber, wherein said exhaust gas stream is guided perpendicular to the exhaust gas stream being distributed out of the at least one outlet of the mixing chamber,
- e) a second guiding means located inside the housing and arranged at the one end of the mixing chamber opposite the at least one outlet of the mixing chamber, said second guiding means having at least one inlet adapted to receive and guide the exhaust gas stream to the mixing chamber, wherein said exhaust gas stream is guided perpendicular to the exhaust gas stream being distributed out of the at least one outlet of the mixing chamber, and wherein the second guiding means has an opening for introducing the reductant into the mixing chamber.
