    Abstract: A dosing and mixing arrangement including an exhaust conduit defining a central axis; a mixing conduit positioned within the exhaust conduit; a dispersing arrangement (e.g., a mesh) disposed at the upstream end of the mixing conduit; an injector coupled to the exhaust conduit and configured to direct reactants into the exhaust conduit towards the mesh; and an annular bypass defined between the mixing conduit and the exhaust conduit for allowing exhaust to bypass the upstream end of the mixing conduit and to enter the mixing conduit downstream of the mesh.
    Type: Grant
    Filed: July 23, 2018
    Date of Patent: November 24, 2020
    Assignee: Donaldson Company, Inc.
