Patent number: 9765675Abstract: Incorporated in an exhaust pipe are an HC-SCR NOx catalyst capable of reducing NOx at temperatures less than a set temperature T and a catalyzed particulate filter with an oxidation catalyst capable of reducing NOx at temperatures not less than the set temperature T. When an exhaust gas temperature is less than the set temperature T, fuel with a set flow rate Q is intermittently added from a fuel addition unit on an entry side of the HC-SCR NOx catalyst to the HC-SCR NOx catalyst; when the exhaust gas temperature is not less than the set temperature T, the fuel with flow rate Q? not less than the set flow rate Q is temporarily rich-spike added from the fuel addition unit and is made arrival at a catalyzed particulate filter. With an active temperature range being expanded, exhaust emission control is performed in a wide temperature range.Type: GrantFiled: December 25, 2013Date of Patent: September 19, 2017Assignee: HINO MOTORS, LTD.Inventors: Keiichi Hayashizaki, Shinya Sato, Hiroshi Hirabayashi, Mitsuru Hosoya

Patent number: 9623376Abstract: A carrier gas supplied from a carrier gas source is injected from a carrier gas injection nozzle. Also, a fuel including a hydrocarbon-based liquid and supplied from a fuel source is supplied to a tip end of the carrier gas injection nozzle, whereby this fuel is atomized with the carrier gas injected from the carrier gas injection nozzle. Furthermore, an inlet of a reforming part that decomposes the atomized fuel and reforms the atomized fuel into a reducing gas including either or both of hydrogen and an oxygen-containing hydrocarbon is provided so as to face the carrier gas injection nozzle and the fuel supply nozzle, and a reducing gas supply nozzle that supplies the reducing gas discharged from an outlet of the reforming part is provided in an exhaust pipe.Type: GrantFiled: September 12, 2012Date of Patent: April 18, 2017Assignee: HINO MOTORS, LTD.Inventors: Hiroshi Hirabayashi, Mitsuru Hosoya, Keiichi Hayashizaki, Shinya Sato, Yoshihiro Kawada, Satoshi Sato, Hiroshi Inoue

Patent number: 9145805Abstract: A first selective reduction catalyst including a silver-based catalyst is provided in an exhaust pipe of an engine. An ozone generation device generates ozone by using oxygen in the atmosphere, and a hydrocarbon-based liquid supply device supplies a hydrocarbon-based liquid. A part of NO in the exhaust gas flowing through the exhaust pipe is oxidized to NO2 with the ozone generated by the ozone generation device, and said NO2 is supplied to the first selective reduction catalyst. Also, a part of the hydrocarbon-based liquid supplied by the hydrocarbon-based liquid supply device is partially oxidized, with ozone generated by the ozone generation device, to an active reducing agent including an oxygen-containing hydrocarbon such as aldehyde, and this active reducing agent is supplied to the first selective reduction catalyst.Type: GrantFiled: September 3, 2012Date of Patent: September 29, 2015Assignee: Hino Motors, Ltd.Inventors: Shinya Sato, Hiroshi Hirabayashi, Keiichi Hayashizaki, Yoshihiro Kawada, Mitsuru Hosoya
