Patent number: 10493410Abstract: A selective catalytic reduction including a decomposition section including an intake chamber, with a swirl generating plate disposed in an internal volume of the intake chamber. The swirl generating plate includes a curved sidewall, a first end defining an opening, and a second end. The curved sidewall is oriented substantially normal to the direction of an intake flow of exhaust gas and a convex surface of the curved sidewall is oriented to face the direction of the intake flow. The swirl generating plate is configured to divide the intake flow into a first flow portion flowing through the opening, a second and a third flow portion which are directed substantially normal to the direction of intake flow and the flow direction of the first flow portion, and in opposite directions to each other towards a backwall of the intake chamber so as to create opposing swirls.Type: GrantFiled: January 9, 2015Date of Patent: December 3, 2019Assignee: Cummins Emission Solutions Inc.Inventors: Karthik Muruganantham, Achuth Munnannur, Deepesh Goyal, Rahul Suresh, Santosh Kumar Pradhan, Vinay Kumar Joshi, Ramayodhya Pandit

Patent number: 9869225Abstract: A system and method for providing a selective catalytic reduction system with a doser mounting system. A mounting plate includes an aperture in a surface with a plurality of fastener brackets coupled to the surface. The fastener brackets are positioned about a peripheral portion of the aperture. The fastener brackets each include an opening for inserting a fastener. The opening is elevated from the surface of the mounting plate. The fasteners each have a fastener head and a fastener shaft positioned in the opening of the fastener brackets. The fastener shaft extends from the opening in a direction having an orthogonal component with respect to the surface of the mounting plate. A doser is coupled to the doser mounting system. The fastener shafts extend through openings in legs of the doser. An injector port of the doser is aligned with the aperture in the mounting plate.Type: GrantFiled: March 3, 2015Date of Patent: January 16, 2018Assignee: Cummins Emission Solutions, Inc.Inventors: Karthik Muruganantham, Achuth Munnannur, Deepesh Goyal, Ken Hummel, Vinay Kumar Joshi, Vipin Iyer

Patent number: 9644512Abstract: A dosing module for an exhaust aftertreatment system includes an attachment interface for coupling to an exhaust system. The attachment interface includes a heat pipe system that includes a cavity encasing a fluid. The cavity has a heat source portion thermally coupled with a portion of the attachment interface and a heat sink portion thermally coupled with a cooling system. The fluid transfers heat from the heat source portion to the heat sink portion.Type: GrantFiled: May 5, 2015Date of Patent: May 9, 2017Assignee: CUMMINS EMISSION SOLUTIONS, INC.Inventor: Karthik Muruganantham

Patent number: 9528418Abstract: An aftertreatment system comprises a first passageway to receive a first portion and a second passageway to receive a second portion of the exhaust gas from the engine. The first and second passageways can have the same length. A first selective catalytic reduction system is fluidly coupled to the first passageway to receive and treat the first portion. A second selective catalytic reduction system is fluidly coupled to the second passageway to receive and treat the second portion. A plurality of sensors are disposed on the first passageway and/or the first selective catalytic reduction system to sense operational parameters of the first portion of the exhaust gas. A controller is in electronic communication with the plurality of sensors to determine the operational parameters of the first portion and to determine operational parameters of the second portion of the exhaust gas based upon the first operational parameters.Type: GrantFiled: January 15, 2015Date of Patent: December 27, 2016Assignee: CUMMINS EMISSION SOLUTIONS, INC.Inventor: Karthik Muruganantham
