A mixing chamber is used for treatment of diesel exhaust. The mixing chamber includes a mixing pipe that permits passage of diesel exhaust, an insertion pipe that inserts the diesel exhaust into the mixing pipe near the first end of the mixing pipe such that the diesel exhaust entering the mixing pipe has angular momentum with respect to a longitudinal axis of the mixing pipe, and a mixer that introduces gaseous ammonia into the diesel exhaust with the atomized diesel exhaust fluid (DEF). The mixing pipe includes a DEF doser that injects the atomized DEF into the diesel exhaust. The mixing pipe has a larger cross section than the insertion pipe. The insertion pipe guides the diesel exhaust into the mixing pipe before the location of the DEF doser. |
