Abstract

A mixing chamber can be used for treatment of diesel exhaust. The mixing chamber can include 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 introduced gaseous ammonia into the diesel exhaust injected with the atomized diesel exhaust fluid (DEF). The mixing pipe can include a DEF doser that injects the atomized DEF into the diesel exhaust. The mixing pipe can have a larger cross section than the insertion pipe. The insertion pipe can insert the diesel exhaust into the mixing pipe before the location of the DEF doser.
