Patent number: 10145343Abstract: A timing-based method for regenerating a DOC included in an aftertreatment system fluidly coupled to a dual-fuel engine comprises performing at least one of the following: a temperature of the DOC is varied while flowing a mixed exhaust gas, which comprises a mixture of a diesel-only exhaust gas and a natural gas exhaust gas, generated by the dual-fuel engine through the DOC; alternately the method includes flowing (a) the mixed exhaust gas generated by the dual-fuel engine and (b) a diesel-only exhaust gas generated by the dual-fuel engine through the DOC.Type: GrantFiled: May 13, 2015Date of Patent: December 4, 2018Assignee: CUMMINS EMISSION SOLUTIONS, INC.Inventors: Yi Liu, Justin Kruer, Rahul B. Kallurwar, Arvind V. Harinath, Zheng Liu

Patent number: 9677445Abstract: Systems and methods to selectively control plurality of dosing modules may include receiving data indicative of an exhaust flow rate. An amount of reductant to be dosed may be determined based, at least in part, on the data indicative of the exhaust flow rate. A decomposition delay time may also be determined and a first dosing module and a second dosing module may be selectively activated. The first dosing module may be selectively activated at a first time and the second dosing module is selectively activated at a second time. The second time is based on the first time and the determined decomposition delay time.Type: GrantFiled: December 13, 2016Date of Patent: June 13, 2017Assignee: Cummins Emission Solutions, Inc.Inventors: Rafael Nunez, Atul Abhyankar, Ken Hummel, Justin Kruer, Tyler Lorenz, Farshad Farid, Arun Shori Sundaravel

Patent number: 9482135Abstract: A diesel oxidation catalyst component may include an inlet, an outlet, and a catalyst chamber body in fluid communication with the inlet and the outlet. An angled jacking bolt assembly is configured to secure a diesel oxidation catalyst within a catalyst chamber defined by the catalyst chamber body. In some implementations, a spacing component or a second diesel oxidation catalyst may be included and secured by the angled jacking bolt assembly. The catalyst chamber body may include an access panel assembly that includes an access panel and securing bolts. The access panel assembly may substantially fluidly seal an opening defined by a mount of the catalyst chamber body when the access panel is secured to the mount by the plurality of securing bolts. The opening may be sized to permit removal of the diesel oxidation catalyst from within the catalyst chamber.Type: GrantFiled: August 11, 2014Date of Patent: November 1, 2016Assignee: CUMMINS EMISSION SOLUTIONS, INC.Inventors: Tyler Lorenz, Vipin Iyer, Ken Hummel, Rahul Kallurwar, Justin Kruer, James Klingbeil

Patent number: 9297286Abstract: A system includes an internal combustion engine. An aftertreatment system is coupled to the internal combustion engine to receive an exhaust gas stream. The aftertreatment system comprises one or modules. Each module includes one or more emission reducing devices to reduce undesirable constituents in the exhaust gas stream from the internal combustion engine.Type: GrantFiled: November 1, 2012Date of Patent: March 29, 2016Assignee: CUMMINS EMISSION SOLUTIONS INC.Inventors: Justin Kruer, Atul Abhyankar, John Ringstad, Ken Hummel
