Publication number: 20110011058Abstract: With a turbofan engine the inner sidewall (2) of the bypass duct (3) features, downstream of the flow divider (11), a straight, conically widening form which, downstream of the supports, struts and guide vanes (7), smoothly transits into a circular-arc transition area (22). The form of the engine fairing (1) is adaptable to the shape of the inner sidewall (2), so that the bypass duct (3) has a conically flaring shape. In the interior of the engine, the gearbox (14) and/or other installations are arranged in a space existing between the inner sidewall (2) and a separating wall (4) confining the core-flow duct (5). The conical design of the bypass duct with the circular-arc transition area enables the gearbox and other installations to be arranged in the engine interior and, furthermore, is aeroacoustically and aerodynamically favorable.Type: ApplicationFiled: July 16, 2010Publication date: January 20, 2011Applicant: ROLLS-ROYCE DEUTSCHLAND LTD & CO KGInventor: Carsten CLEMEN

Publication number: 20110011059Abstract: An exhaust gas treating apparatus includes an adsorption tower (20) that has an adsorption layer filled with an adsorbent and a heat transfer path through which heat is transferred to the adsorption layer. The apparatus performs switching among the following processes: an adsorption process of introducing an exhaust gas from an engine (10) into the adsorption layer of the adsorption tower so that target components to be treated, including NOX, in the exhaust gas are adsorbed by the adsorbent; a desorption process of introducing the exhaust gas into the heat transfer path of the adsorption tower to heat the adsorption layer and introducing a desorption gas into the heated adsorption layer so that the target components are desorbed from the adsorbent, and a cooling process of introducing a cooling gas into the adsorption layer of the adsorption tower to cool the adsorption layer and introducing the cooling gas that has passed through the adsorption layer into an inlet of the engine.Type: ApplicationFiled: August 28, 2008Publication date: January 20, 2011Applicants: Osaka Prefecture University Public Corporation, Japan Science and Technology AgencyInventors: Keiichiro Yoshida, Masaaki Okubo

Publication number: 20110011060Abstract: An exhaust aftertreatment system having a NOX absorber-catalyst and an ammonia-SCR reactor. During regenerations, the NOX absorber-catalyst generates ammonia. The ammonia-SCR reactor captures this ammonia and later uses it to reduce NOX. A Venturi is provided in an exhaust conduit connecting the NOX absorber-catalyst to the ammonia-SCR reactor. The Venturi draws sufficient air to keep the ammonia-SCR reactor under lean conditions throughout the NOX absorber-catalyst regenerations. Maintaining lean conditions for the ammonia-SCR reactor in this manner mitigates poisoning of the ammonia-SCR reactor by hydrocarbons slipping from the NOX absorber-catalyst during the regenerations. Mitigating this poisoning improves the performance of the exhaust aftertreatment system and reduce the loss of useful ammonia to oxidation.Type: ApplicationFiled: April 16, 2010Publication date: January 20, 2011Applicant: Eaton CorporationInventor: James Edward McCarthy, JR.

Publication number: 20110011061Abstract: In a specified operating area including a low engine-speed and low engine-load area, an excess air ratio ? is set at a specified ratio which is two or greater and three or smaller and an ignition timing ?ig of a spark plug is set at a timing of MBT to provide the maximum torque as a normal combustion control (S4). In case a catalyst temperature Tc is lower than a predetermined first temperature T1 in this area, a control of retarding the ignition timing from the MBT timing and/or a control of decreasing the excess air ratio ? to a ration below the above-described ratio are executed (S6, S8, S9). Accordingly, the temperature of the catalyst can be prevented simply and effectively from decreasing excessively, maintaining combustion conditions to provide a properly high thermal efficiency.Type: ApplicationFiled: June 30, 2010Publication date: January 20, 2011Applicant: MAZDA MOTOR CORPORATIONInventors: Masahisa YAMAKAWA, Takashi YOUSO, Kouhei IWAI, Shuji OBA

Publication number: 20110011062Abstract: Method of controlling the active regeneration of a particulate filter through dynamic control of the temperature at the outlet of an oxidation catalyst. A control law is defined for a hydrocarbon flow rate at the oxidation catalyst inlet, by means of the ratio between a temperature demand and a gain. The gain can be corrected so as to take account of the transient phenomena that occur in the oxidation catalyst during a gas flow rate variation. The temperature demand can comprise a precompensation term to compensate for the effects of a temperature variation at the oxidation catalyst inlet. The temperature demand can comprise a feedback term calculated by a controller whose parameters are automatically calculated by means of a physical model of the catalyst, during operating conditions variations. Any combination of these terms allows to define a suitable control law.Type: ApplicationFiled: July 8, 2010Publication date: January 20, 2011Inventors: Olivier Lepreux, Yann Creff, Nicolas Petit

The control modes for the exhaust gas control apparatus include a first control mode where the fuel is supplied from the fuel supply valve, heated by the glow plug, and ignited, a second control mode where the fuel is supplied from the fuel supply valve, and heated by the glow plug but is not ignited, and a third control mode where the fuel is supplied from the fuel supply valve and the glow plug does not provide heating. The electronic control unit selects the first or third control mode in the operation region where ignition is possible, and selects the second or third control mode in the operation region where ignition is not possible.Type: ApplicationFiled: September 3, 2009Publication date: January 20, 2011Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Kenichi Tsujimoto, Mikio Inoue
