Publication number: 20040237508Abstract: A characteristic change of a humidity sensor 19 is detected based on the transitional characteristics of output data of the humidity sensor 19 with respect to integrated moisture quantity data representative of an integrated amount of moisture that is supplied to an HC adsorbent 7 by an exhaust gas after an engine 1 has started to operate. Data of characteristics of an individual unit of the humidity sensor 19 is held by the resistance of a resistive element 21 connected to a connector or the like of the humidity sensor 19. A parameter for grasping a state of the HC adsorbent 7 is corrected depending on the detected characteristic change of the humidity sensor 19 and the characteristics of the individual unit of the humidity sensor 19, and the state of the HC adsorbent 7 is grasped based on the corrected parameter.Type: ApplicationFiled: April 6, 2004Publication date: December 2, 2004Inventors: Hideharu Yamazaki, Masahiro Sato, Kei Machida, Tetsuo Endo, Masaki Ueno

Publication number: 20040237509Abstract: A system for supplying clean pressurized air to a diesel oxidation catalyst (DOC) includes a diesel engine, a turbocharger, and a DOC. The diesel engine having an outlet that presents an exhaust gas. The turbocharger receives at least a first portion of the exhaust gas and clean air, and presents uncooled pressurized clean air. The DOC receives a combination of the at least first portion of the exhaust gas and at least a second portion of the uncooled pressurized clean air.Type: ApplicationFiled: May 29, 2003Publication date: December 2, 2004Applicant: Detroit Diesel CorporationInventors: Sameer Bhargava, Kevin Dean Sisken

Publication number: 20040237510Abstract: During the catalyst warm-up period, when control enabling reduction in hydrocarbons is not executed in gasoline engine 100, the opening of the throttle valve 101 is made smaller in order to reduce the hydrocarbon discharge. During the catalyst warm-up period, when control enabling reduction in the quantity of hydrocarbons is executed in gasoline engine 100, the opening of the throttle valve 101 is made larger in order to accelerate warm-up of the catalyst, thereby shortening the catalyst warm-up period. A shorter catalyst warm-up period enables reduction in the total quantity of hydrocarbons from engine startup to the end of the catalyst warm-up period.Type: ApplicationFiled: May 19, 2004Publication date: December 2, 2004Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Masaki Kusada, Katsuhiko Yamaguchi, Toshio Inoue

Publication number: 20040237511Abstract: A mixing device for mixing the exhaust gas of an internal combustion engine flowing in an exhaust pipe with a reducing agent as well as an exhaust gas purification system having such a mixing device are described. A mixing body that is positionable in the exhaust pipe and having a gas impact surface and a spray impact surface is provided so that exhaust gas flowing from the internal combustion engine is able to strike the gas impact surface and reducing agent, which is suppliable transversely to the exhaust gas flow, is able strike the spray impact surface, the spray impact surface and the gas impact surface forming disjointed sub-areas of the surface of the mixing body. The mixing device distributes the reducing agent uniformly over the cross section of the exhaust pipe and mixes it uniformly with the exhaust gas.Type: ApplicationFiled: July 8, 2004Publication date: December 2, 2004Inventors: Wolfgang Ripper, Bernd Mahr, Johannes Schaller, Cord Scharsack, Thomas Prasser

Publication number: 20040237512Abstract: A hydrogen fueled reciprocating spark ignition engine includes a fuel system for providing gaseous hydrogen to the cylinders of the engine and a lean NOx trap coupled to the engine for treating the engine's exhaust. An EGR system provides recirculated exhaust gas to the engine, and a controller operates the fuel system and EGR system during periodic purging of the lean NOx trap such that the engine is operated fuel rich, with the mass of EGR approximating 40%-80% of the mass of air and fuel.Type: ApplicationFiled: July 21, 2004Publication date: December 2, 2004Applicant: FORD GLOBAL TECHNOLOGIES LLCInventors: XIAOGUO TANG, JOSEPH ROBERT THEIS, ROBERT JAY NATKIN, SIAMAK HASHEMI, WILLIAM F.

Publication number: 20040237513Abstract: A system for controlling the temperature of a particulate filter coupled to an exhaust outlet of an internal combustion engine includes a controller responsive to volumetric flow and temperature of exhaust gas to determine a filter regeneration parameter. In a hybrid electric-engine vehicle application, various control strategies are implemented as a function of the regeneration parameter to control exhaust gas temperature suitably for proper regeneration of the particulate filter. Such strategies include shifting the duty cycle of the engine toward lower engine speed operation along lines of constant power output, modifying the ratio of electrical power and engine power and controlling recharging of the battery supplying electrical energy to the vehicle's electric drive motor under vehicle deceleration conditions.Type: ApplicationFiled: June 24, 2004Publication date: December 2, 2004Inventors: Bruce G.
