Patent number: 11591949Abstract: An aftertreatment system for treating constituents of an exhaust gas produced by an engine includes a heater configured to selectively heat the exhaust gas entering the aftertreatment system. An aftertreatment component is disposed downstream of the heater. A gas sensor is disposed downstream of the heater and upstream of the aftertreatment component. The gas sensor comprises a sensing element, and a heating element configured to selectively heat the sensing element to an operating temperature of the sensing element.Type: GrantFiled: February 28, 2022Date of Patent: February 28, 2023Assignee: Cummins Emission Solutions Inc.Inventors: Colin L. Norris, Andrew W. Osburn, Ryan M. Johnson, Todd A. Corbet, Kyle Robert Fath, Lindsey R. Henry, Baseer Faalzada

Publication number: 20220298949Abstract: An aftertreatment system includes an exhaust gas conduit, a mixer, and a mixing flange. The exhaust gas conduit includes an inner surface. The exhaust gas conduit has a conduit diameter dc. The mixer includes a mixer body and an upstream vane plate. The upstream vane plate has a plurality of upstream vanes. At least one of the plurality of upstream vanes is coupled to the mixer body. The mixing flange is disposed downstream of the mixer. The mixing flange includes a mixing flange opening having a mixing flange opening diameter dmf. 0.30*dc?dmf?0.95*dc.Type: ApplicationFiled: March 15, 2022Publication date: September 22, 2022Applicant: Cummins Emission Solutions Inc.Inventors: Mihai Chiruta, Isabel Valborg Montgomery, Lindsey R.

Patent number: 10024213Abstract: One form of the present application is an apparatus including an internal combustion engine structured to produce an exhaust flow, an exhaust system structured to receive the exhaust flow, and a reductant injector structured to inject reductant into a primary passage of the exhaust system upstream of a catalyst. The apparatus further includes an injector passage structured to receive a portion of exhaust upstream of the injector and further structured to flow the exhaust into the primary passage around the injector in a manner such that deposit formation is reduced.Type: GrantFiled: November 28, 2016Date of Patent: July 17, 2018Assignee: CUMMINS EMISSION SOLUTIONS INC.Inventors: Douglas A. Mitchell, Mihai Chiruta, Lindsey R. Henry, Jim Alonzo

Patent number: 9650933Abstract: An exhaust assisted pipe assembly including an outer portion having an opening for receiving dosed reductant from a dosing module and an inner portion disposed within the outer portion. The inner portion defines a main flow path for receiving a first portion of a fluid from an upstream source, and the inner portion and the outer portion cooperatively define a first flow path and a second flow path. The first flow path is configured to direct a second portion of the fluid from the upstream source past the opening for receiving dosed reductant and into the main flow path to increase momentum of the dosed reductant into the main flow path. The second flow path is configured to direct a third portion of the fluid from the upstream source toward the dosed reductant to decrease the momentum of the dosed reductant in the main flow path.Type: GrantFiled: June 9, 2015Date of Patent: May 16, 2017Assignee: CUMMINS EMISSION SOLUTIONS, INC.Inventors: Mihai Chiruta, Lindsey R. Henry, Douglas A. Mitchell, Randy G. Zoran, George E. Mavroudis, Lauren A. Lynch
