Abstract

A vehicle exhaust system includes an exhaust component defining an engine exhaust gas passageway and which includes an opening. A doser defines a doser axis and extends to a doser tip that is configured to spray a reducing agent into the engine exhaust gas passageway through the opening. A cone has a base end positioned adjacent the opening such that an annular gap is formed within the exhaust component around the doser tip. Exhaust gas is directed into the base end of the cone through the annular gap in a direction transverse to the doser axis. This configuration reduces deposit formation while still allowing the reducing agent to be thoroughly mixed with engine exhaust gases prior to introduction of the mixture into a downstream exhaust component.
