The exhaust gas purification system comprises an SCR catalyst for reducing and removing nitrogen oxides in an exhaust gas from an engine (10) by bringing the nitrogen oxides into contact with a reducing agent, oxidation catalysts (11, 17) for oxidizing gas components in the exhaust gas, a water electrolysis device (24) for producing oxygen by electrolyzing water, and an oxygen supply pipe (29) for supplying the oxygen produced by the water electrolysis device (24) to the exhaust gas.Type: GrantFiled: September 3, 2008Date of Patent: October 9, 2012Assignee: Mitsubishi Heavy Industries, Ltd.Inventors: Masazumi Tanoura, Shuuji Fujii, Masatoshi Katsuki, Daishi Ueno, Yuko Ujihara

Patent number: 8281578Abstract: A method for correcting an estimated amount of NH3 store within a SCR is described. In one example, SCR efficiency is determined from a NOx sensor output and the estimated amount of NH3 is corrected based on the SCR efficiency. Engine emissions may be reduced via improving the estimated NH3 storage level, at least during some conditions.Type: GrantFiled: March 24, 2011Date of Patent: October 9, 2012Assignee: Ford Global Technologies, LLCInventors: Devesh Upadhyay, Michiel J. Van Nieuwstadt

Patent number: 8281579Abstract: An exhaust system for use with a combustion engine is disclosed. The exhaust system may have a passage connected to receive exhaust from the combustion engine, and a cooling device located external to the passage to create a thermal gradient across a flow area of the passage that causes particulates within the exhaust to agglomerate on a wall of the passage. The exhaust system may also have a filtration device located to separate agglomerated particulates from the exhaust.Type: GrantFiled: May 28, 2008Date of Patent: October 9, 2012Assignee: Caterpillar Inc.Inventors: James J. Driscoll, Wade J. Robel, Praveen S. Chavannavar

Patent number: 8281580Abstract: A method to monitor a particulate filter includes determining an equivalent bypass area corresponding to a difference between a mass flowrate of an exhaust gas feedstream flowing to the particulate filter and a mass flowrate of the exhaust gas feedstream flowing through porous walls of a substrate.Type: GrantFiled: January 19, 2010Date of Patent: October 9, 2012Assignee: GM Global Technology Operations LLCInventor: Min Sun

Patent number: 8281581Abstract: An exhaust aftertreatment device has a unitary cast inlet that is configurable to have a 90° or 180° entry of combustion gasses relative to flow through tubular elements housing a diesel oxidization catalyst and a diesel particulate filter. The cast component provides the primary structural support for a tubular element connected to the casting element.Type: GrantFiled: October 20, 2008Date of Patent: October 9, 2012Assignee: Deere & CompanyInventors: Matthew R. Oliver, David S. Young, Cary Wright, Mike Smith

Patent number: 8281582Abstract: A method for supplying fluid to a transmission component such as a transmission control unit, a transmission lubricating system, and/or a transmission cooling system. The transmission is an automatic transmission of a motor vehicle having a hydraulic actuating system. A hydraulic medium is drawn from a region within the interior of a transmission case by a positive displacement pump, and the region of the transmission case from which the positive displacement pump draws the hydraulic medium is subjected to an overpressure that is somewhat greater than the ambient pressure around the transmission case.Type: GrantFiled: December 6, 2008Date of Patent: October 9, 2012Assignee: Schaeffler Technologies AG & Co. KGInventor: Reinhard Stehr
