Patent number: 9810126Abstract: An exhaust treatment system includes an exhaust conduit for conveying exhaust gases from an engine of a vehicle. An aftertreatment device is disposed in the exhaust conduit. A flow device is disposed upstream of the aftertreatment device. The flow device includes a base having a first surface and an oppositely disposed second surface. The base defines a plurality of openings. A plurality of flow deflectors is engaged to the base at the plurality of openings. Each flow deflector includes a first deflector that extends outwardly from the first surface of the base and a second deflector that extends outwardly from the second surface of the base. The first and second deflectors define a passage. Flow of exhaust gases through the passage cause exhaust gases to swirl about a longitudinal axis of the exhaust conduit.Type: GrantFiled: September 24, 2013Date of Patent: November 7, 2017Assignee: DONALDSON COMPANY, INC.Inventors: Jérôme Lebas, Stanislas Le Tallec, Antoine Provost, Stéphane Le Merdy, Phebe Helena Preethi, Paul Anthony Way

Patent number: 9453447Abstract: The present disclosure relates to a device for mounting an injector to an exhaust pipe. The device includes an injector mounting structure having an exterior surface configured for mounting the injector. The injector mounting structure also includes an interior surface arrangement defining an interior volume and a port for allowing the injector to inject a reductant into the interior volume. The interior surface arrangement is configured to prevent swirling of exhaust within the interior volume.Type: GrantFiled: May 19, 2014Date of Patent: September 27, 2016Assignee: Donaldson Company, Inc.Inventors: Paul Anthony Way, Phebe Preethi, Nathan Zambon, Andrew Alan Gilb

Patent number: 8783022Abstract: An exhaust aftertreatment system for diesel engines includes a filtration station, a NOx reduction station, a temperature sensor, a pressure data generator, a NOx sensor, a reductant dispenser, and a controller. The filtration station filters particulate material from the exhaust. The NOx reduction station reduces NOx concentration in the exhaust. The temperature sensor generates first data that is representative of a temperature of the exhaust. The pressure data generator generates second data that is indicative of a pressure differential across a control volume that is located at the NOx reduction station. The control volume includes at least one catalyzed substrate. The NOx sensor generates third data that is representative of the NOx concentration in the exhaust. The reductant dispenser dispenses reductant into the exhaust. The controller controls a dosing rate of the reductant dispenser. The controller uses the first, second, and third data to determine the dosing rate.Type: GrantFiled: July 29, 2010Date of Patent: July 22, 2014Assignee: Donaldson Company, Inc.Inventors: Henry Joseph Drasner, III, Andrew Alan Gilb, Paul Anthony Way

Patent number: 6779339Abstract: The method of treating a fuel lean exhaust containing NOX and SO2 includes splitting the exhaust into major and minor portions for flow through multiple flow paths each of which contains a particulate trap and an absorber containing a NOX oxidation catalyst and a nitrate absorbent. The major portion is passed through a flow path in the lean state at a first temperature to convert the NOX to nitrate and the SO2 to sulfate. After the first period of operation flows are switched so that one flow path receives a minor exhaust portion for a second period of time during which fuel is injected into that flow path along with diversion of a portion of exhaust from another flow path through a bypass.Type: GrantFiled: May 2, 2003Date of Patent: August 24, 2004Assignee: The United States of America as represented by the Environmental Protection AgencyInventors: Christopher A.
