Patent number: 11891937Abstract: A mixing assembly for an exhaust system can include an outer body, a front plate, a back plate, a middle member, and an inner member. The outer body defines an interior volume and has a center axis. The front plate defines an upstream portion of the interior volume and the back plate defines a downstream portion of the interior volume. The middle member is positioned transverse to the center axis and defines a volume. The inner member is positioned coaxially with the middle member inside the middle member. The front plate includes inlets configured to direct exhaust to (i) a first flow path into an interior of the inner member, (ii) a second flow path into the volume of the middle member between a sidewall of the middle member and a sidewall of the inner member, and (iii) a third flow path into the interior volume of the outer body.Type: GrantFiled: September 19, 2022Date of Patent: February 6, 2024Assignee: Cummins Emission Solutions Inc.Inventors: Matthew K. Volmerding, Ryan M. Johnson, Jim L Alonzo, Samuel Johnson, Apoorv Kalyankar, Pranjal Naik, Kartiki Jagtap, Mahendra Mittapalli

Publication number: 20230151755Abstract: A decomposition chamber for an exhaust gas aftertreatment system includes an inlet tube, a selective catalytic reduction (SCR) catalyst member, a mixing collector wall, a distribution cap, and a dividing tube. The inlet tube is configured to receive exhaust gas. The mixing collector wall includes a mixing assembly flow aperture. The distribution cap is coupled to the inlet tube and configured to receive the exhaust gas from the inlet tube. The dividing tube is coupled to the mixing collector wall. The dividing tube separates the distribution cap from the mixing assembly flow aperture. The dividing tube includes a first dividing tube inlet aperture that is configured to receive the exhaust gas from the distribution cap. The dividing tube outlet aperture is configured to provide the exhaust gas to the mixing assembly flow aperture.Type: ApplicationFiled: December 1, 2020Publication date: May 18, 2023Applicant: Cummins Emission Solutions Inc.Inventors: Samuel Johnson, Paul T. Frisch, Peter Te-Cheng Jang, Randolph G. Zoran, Ryan M. Johnson, John G. Buechler, Jim L. Alonzo, Enoch Nanduru, Pradnya C. Joshi, Mihai Chiruta, Isabel Valborg Montgomery, Guilherme Daldegan
