Publication number: 20180171857Abstract: The present disclosure provides a method of producing an insulation preform having graded porosity for an exhaust treatment component of a vehicle. The method includes obtaining a first granular insulating material having a first diameter, a second granular insulating material having a second diameter less than the first diameter, an inorganic binder, and water. The method further includes producing a slurry comprising the first granular insulating material, the second granular insulating material, the inorganic binder, and water. The slurry is introduced into a mold having at least one surface adapted for vacuum extraction. A liquid phase of the slurry is evacuated from the mold using vacuum extraction to produce a moist preform. The moist preform has graded porosity such that a greater concentration of the second insulation material is adjacent to the at least one surface than the first insulating material. The moist preform is heated to produce the insulation preform.Type: ApplicationFiled: December 21, 2016Publication date: June 21, 2018Inventors: Thomas M. HARRIS, Bradley FINGLAND, Michael C. BRADFORD, Adam J. KOTRBA

Publication number: 20170241317Abstract: An exhaust after-treatment system for treating an exhaust produced by an engine. The exhaust after-treatment system includes an exhaust passage, at least one catalytic exhaust after-treatment component in communication with the exhaust passage for treating the exhaust, and a water-removal device in communication with the exhaust passage that receives a portion of the exhaust therein at a location positioned upstream from the catalytic exhaust after-treatment component. The water-removal device is defined by a housing that includes a water-removal membrane that separates water from the portion of the exhaust to provide a permeate that is enriched with water, and to produce a retentate that is water depleted that facilitates the treating of the exhaust by the catalytic exhaust after-treatment component.Type: ApplicationFiled: February 23, 2016Publication date: August 24, 2017Inventor: Michael C. BRADFORD

Publication number: 20170204762Abstract: An after-treatment system including an exhaust treatment component provided in an exhaust passage, a tank carrying an aqueous reagent, and an electrochemical cell in communication with the tank and configured to receive the aqueous reagent therefrom. The electrochemical cell is configured to convert the aqueous reagent into a first exhaust treatment fluid and a second exhaust treatment fluid. A controller is in communication with the electrochemical cell. The controller is configured to vary amounts and/or composition of each of the first exhaust treatment fluid and the second exhaust treatment fluid produced by the electrochemical cell. An injector is in communication with the electrochemical cell and the exhaust passage, and is configured to receive one of the first exhaust treatment fluid or the second exhaust treatment fluid from the electrochemical cell, and dose the one exhaust treatment fluid into the exhaust passage at a location upstream from the exhaust treatment component.Type: ApplicationFiled: January 20, 2016Publication date: July 20, 2017Inventors: Adam J. KOTRBA, Padmanabha Reddy ETTIREDDY, Michael GOLIN, Michael C. BRADFORD, Bradley FINGLAND

Patent number: 9702291Abstract: An exhaust aftertreatment system may include a reductant tank, a reactor system, a storage tank, a first conduit and a second conduit. The reactor system may receive reductant from the reductant tank and may output a gas comprising ammonia. The storage tank may receive gas comprising ammonia from the reactor system and may store a volume of gas comprising ammonia. The first conduit may communicate gas comprising ammonia from the reactor system to a stream of exhaust gas. The first conduit may bypass the storage tank. The second conduit may communicate gas comprising ammonia from the storage tank to the stream of exhaust gas.Type: GrantFiled: November 3, 2015Date of Patent: July 11, 2017Assignee: Tenneco Automotive Operating Company Inc.Inventors: Padmanabha R. Ettireddy, Bradley Fingland, Adam J. Kotrba, John W. Degeorge, Michael C. Bradford

Publication number: 20170130627Abstract: An exhaust after-treatment system for treating an exhaust produced by an engine. The exhaust after-treatment system includes an exhaust passage, a catalytic exhaust after-treatment component in communication with the exhaust passage for treating the exhaust, and a metal hydride module in communication with the exhaust passage that receives a portion of the exhaust therein at a location positioned upstream from the catalytic exhaust after-treatment component. The portion of the exhaust that enters the metal hydride module reacts with a metal hydride contained in the metal hydride module to produce hydrogen gas that facilitates the treating of the exhaust by the catalytic exhaust after-treatment component.Type: ApplicationFiled: November 10, 2015Publication date: May 11, 2017Inventor: Michael C. BRADFORD
