Claim Text:
1. A dosing and mixing arrangement comprising: an exhaust conduit defining a central axis; a mixing conduit positioned within the exhaust conduit, the mixing conduit extending along the central axis from an upstream end to a downstream end; a disperser for dispersing reactants disposed at the upstream end of the mixing conduit, the disperser including a first region and a second region that is less restrictive than the first region, the first region extending across the upstream end of the mixing conduit; and a bypass for allowing exhaust to bypass the upstream end of the mixing conduit and to enter the mixing conduit downstream of the disperser, the second region of the disperser at least partially restricting access to the bypass; an interior of the mixing conduit being devoid of structure in longitudinal alignment with an upstream face of the disperser.
