Patent number: 7908844Abstract: In an internal combustion engine, a first exhaust passage and second exhaust passage branched from an exhaust passage are provided. An NOx storing reduction catalyst and a particulate filter are arranged in each exhaust passage. For example, when NOx should be released from the NOx storing reduction catalyst in the first exhaust passage, fuel is added from a fuel addition valve in the state with exhaust gas allowed to flow into only the first exhaust passage, while when the added fuel sticks to the NOx storing reduction catalyst, the first exhaust control valve is temporarily closed and the exhaust gas is made a rich air-fuel ratio.Type: GrantFiled: April 28, 2006Date of Patent: March 22, 2011Assignee: Toyota Jidosha Kabushiki KaishaInventors: Shinji Kamoshita, Shigeru Itabashi, Kuniaki Niimi, Tomihisa Oda, Shinya Hirota

Patent number: 5848581Abstract: A diesel engine has a fuel injection nozzle to which pressurized fuel is supplied from a pump. The nozzle has a pressure sensor detecting the fuel pressure and a lift sensor sensing a lift magnitude of a needle valve. An electronic control unit (ECU) computes a variation ratio of the fuel pressure value which is measured by the pressure sensor. The ECU computes a non-increasing point in an increasing part of variation ratio and judges the point to be a timing for starting the fuel injection of the nozzle. The EPU also computes the actual fuel injection amount in accordance with the fuel injection timing as well as the fuel pressure and the lift amount of the needle valve both at the various points. The EPU controls the actual injection amount to be identical to a target fuel injection amount.Type: GrantFiled: June 2, 1995Date of Patent: December 15, 1998Assignee: Toyota Jidosha Kabushiki KaishaInventors: Katsuhiko Hirose, Takao Tate, Norihiko Nakamura, Takeshi Sato, Kazuhiro Iwahashi, Shinji Kamoshita, Akihiro Yamanaka

Patent number: 5513609Abstract: A fuel injection system with a fuel injection pump. The system comprises first correction means for correcting a first basic volume of fuel fed by the fuel injection pump using a correction value calculated so as to realize a predetermined constant engine speed during at least one predetermined engine operating condition, calculation mean for calculating the variation of the correction value corresponding to the fuel temperature at predetermined engine load in the predetermined engine operating condition, and determining means for determining at least one property of current fuel on the basis of the variation. Accordingly, the system can automatically detect the properties of a fuel while driving.Type: GrantFiled: August 16, 1994Date of Patent: May 7, 1996Assignee: Toyota Jidosha Kabushiki KaishaInventors: Katsuhiko Hirose, Shinji Kamoshita
