  • Patent number: 10940451
    Abstract: An exhaust treatment arrangement includes a mixing assembly disposed between first and second substrates; and an injection mounting location disposed at the mixing assembly. The mixing assembly includes a mixing arrangement configured to direct exhaust flow exiting the first substrate in a swirling configuration, a restricting member defining a restricted passage, and optionally a dispersing member configured to even out the exhaust flow.
    Type: Grant
    Filed: December 21, 2018
    Date of Patent: March 9, 2021
    Assignee: Donaldson Company, Inc.
    Inventors: Mark Thomas Brandl, Korneel De Rudder, Bruce Hoppenstedt, Matthew S. Whitten
  • Patent number: 10844764
    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.

  • Publication number: 20180328248
    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.

  • Patent number: 8470253
    Abstract: The present disclosure relates to an diesel exhaust treatment device including a main body having a central longitudinal axis that extends between first and second ends of the main body. A catalyzed substrate is positioned within an interior of the main body. A side inlet is positioned at a side of the main body for directing exhaust gas into the interior of the main body. A flow distribution element is positioned within the interior of the main body at a location between the side inlet and an upstream face of the substrate. The flow distribution element extends across a direction of exhaust flow through the main body and is mounted at a side of the main body that is opposite the side inlet.
