Patent number: 9970342Abstract: An exhaust gas purification device is equipped with: an NOx purification unit disposed in exhaust gas piping of an engine supporting an NOx storage catalyst (NSC); a catalyzed soot filter (CSF) disposed downstream of the NOx purification unit supporting a particulate combustion catalyst causing captured particulates to combust; and an electronic control unit (ECU) which controls exhaust gas flowing into the NSC to be rich and which, by raising the temperature of the NSC, acts as a regeneration device that causes sulfur components captured in the NSC to be desorbed. The particulate combustion catalyst is provided where Ag and Pd have been alloyed on an Al2O3 carrier; the quantity of Ag supported by the Al2O3 carrier is 1.2-2.5 g/L; the quantity of Pd supported by the Al2O3 carrier is 0.7 g/L or less; and the ratio Ag/Pd of the Ag support quantity to the Pd support quantity is 1.7-8.3.Type: GrantFiled: January 29, 2016Date of Patent: May 15, 2018Assignees: HONDA MOTOR CO., LTD., MITSUI MINING & SMELTING CO., LTD.Inventors: Ryosaku Takahara, Koichi Inaba, Nobuhiro Komatsu, Masafumi Sakota, Takahiro Kogawa, Michitaka Yamaguchi

Patent number: 8186149Abstract: A NOx reduction system comprises NOx treatment catalyst and air-fuel ratio control switch for changing the air-fuel ratio of an exhaust gas to a lean or rich state. The NOx treatment catalyst comprises at least a first catalyst layer containing a solid acid catalyst capable of adsorbing ammonia and a second catalyst layer containing a noble metal and a cerium oxide material. The second and the first catalyst layer are stacked in that order on a carrier, and the first catalyst layer constitutes the uppermost layer. NOx is passed through the first catalyst layer in the lean state and is temporarily stored in the second catalyst layer. Thereafter, in the rich state, NOx is converted to NH3 and is restored in the first catalyst layer. When the state is again returned to the lean state, NH3 is converted to nitrogen which is finally released from the first catalyst layer.Type: GrantFiled: July 30, 2007Date of Patent: May 29, 2012Assignee: Honda Motor Co., Ltd.Inventors: Naohiro Satoh, Osami Yamamoto, Koichi Inaba, Hiroshi Ohno

Publication number: 20070018830Abstract: A vehicle component tamper detection system is provided capable of appropriately preventing tampering from occurring, and of facilitating and ensuring detection of such tampering when it occurs, while maintaining flexibility in layout and in manufacturing processes. The present invention omits wiring between an RFID 12 and an ECU 14 by employing a small radio frequency identification integrated circuit (RFID) to wirelessly transmit signals to a receiver 13. With this configuration, the present invention contributes to increased layout flexibility as well as a reduction in assembly steps and manufacturing costs. Furthermore, because the RFID 12 is small, the RFID 12 may be mixed in slurry and disposed at an inconspicuous portion of a detection target component 11. Subsequently, it is possible to hinder visual confirmation of the RFID 12, thereby making the tampering itself difficult.Type: ApplicationFiled: June 28, 2006Publication date: January 25, 2007Inventors: Narizane Inoue, Koichi Inaba, Tsuyoshi Eguchi, Tatsuya Okayama, Atsuhiro Miyauchi
