Abstract

In one non-limiting embodiment, an apparatus for treating exhaust includes a reductant injector, an aftertreatment component including a NOx reduction catalyst, and a pathway for directing exhaust to the aftertreatment component. The pathway includes a constriction zone within which is positioned a mixing member. The constriction zone begins downstream of the reductant injector and upstream from the aftertreatment component. However, other embodiments, forms and applications are also envisioned.
