Patent number: 10408110Abstract: A decomposition reactor for an exhaust system includes an exterior component defining an internal volume and having an inlet and an outlet with the inlet and outlet are formed on a same side of the exterior component. A flow divider is positioned within the internal volume and defines a thermal management chamber and a main flow chamber. A first flow path of exhaust flows from the inlet into the main flow chamber to mix with dosed, and a second flow path of exhaust flows from the inlet into the thermal management chamber to control a temperature of a portion of the flow divider. In some implementations, one or more swirling diverters can be coupled to the flow divider and positioned proximate the outlet of the exterior component to impart a vortical motion to a combined reductant and exhaust gas flow exiting out the outlet.Type: GrantFiled: June 18, 2018Date of Patent: September 10, 2019Assignee: Cummins Emission Solutions Inc.Inventors: Ryan Johnson, Udit Bhaveshkumar Shah, Samuel Johnson, Mahendra Mittapalli, Kartiki Jagtap

Patent number: 9470132Abstract: Various embodiments provide for apparatuses and systems involving a reactor pipe configured to receive reductant from an injector into a flow of exhaust exiting an engine. The reactor pipe comprises an inlet portion, a plurality of louvers, an outlet portion, and a radial loop. The inlet portion is structured to receive the flow exiting the engine into the reactor pipe. The louvers are structured to alter a direction of the flow. Further, the radial loop is configured to extend between the inlet portion and the outlet portion and receives the flow of exhaust through the inlet portion. The radial loop also directs the flow of the exhaust toward the outlet portion and reduces the velocity of the flow of the exhaust such that the reductant has an increased amount of time to react with the exhaust.Type: GrantFiled: December 5, 2014Date of Patent: October 18, 2016Assignee: CUMMINS EMISSION SOLUTIONS, INC.Inventors: Douglas A. Mitchell, Ryan M. Johnson, Kartiki Jagtap, Mahendra Mittapalli, Mihai Chiruta
