DOSING CONDUIT ARRANGEMENTS FOR EXHAUST AFTERTREATMENT SYSTEM

Last updated:

Abstract:

An aftertreatment device includes flow guides disposed within a dosing conduit. Exhaust enters through a perforated region of the dosing conduit and passes through the flow guides. The flow guides induce swirling or other turbulence to mix injected reactant with the exhaust gas. Various types of flow guides include cantilevered vanes, guide passageways, and louvered openings of a second conduit. Some types of flow guides induce localized mixing to inhibit deposit formation at the doser mounting unit. Other types of flow guides induce mixing downstream of the dosing conduit.
