1. A mixing system, comprising:
a housing defining a boundary of a mixing conduit including an expansion section with an injector mount; a reductant diverter extending into the mixing conduit upstream of the injector mount in the expansion section; an atomizer with openings positioned in the housing; and a helical mixing element positioned in the housing, where the helical mixing element includes a first helical mixing surface and a second helical mixing surface, each of the surfaces spirally extending axially through a portion of the housing, a pitch between the first and second helical mixing surfaces decreasing in a downstream direction.
