20130139795 | FAILURE DIAGNOSIS APPARATUS OF EGR SYSTEM - In the engine including an MPL-EGR system having an HPL-EGR mechanism | 06-06-2013 |
20130216436 | CATALYST DETERIORATION JUDGING SYSTEM - The deterioration judgment for an absorption reduction type NOx catalyst is performed quickly and correctly. A catalyst deterioration judging system includes a supply unit which supplies a reducing agent, a measuring unit which measures a NOx concentration in an exhaust gas at a position downstream from the catalyst, a control unit which regulates an amount of the reducing agent so that an air-fuel ratio of the exhaust gas is a lean air-fuel ratio when the reducing agent is supplied from the supply unit, and a judging unit which judges deterioration of the catalyst on the basis of the NOx concentration measured by the measuring unit when the amount of the reducing agent is regulated so that the air-fuel ratio of the exhaust gas is the lean air-fuel ratio when NOx is absorbed by the catalyst. | 08-22-2013 |
20130330234 | CATALYST DETERIORATION JUDGING SYSTEM - The deterioration judgment for an absorption reduction type NOx catalyst is performed quickly and correctly. A catalyst deterioration judging system includes a judging unit which judges that the absorption reduction type NOx catalyst is deteriorated if a detected value of an NH | 12-12-2013 |
20130336841 | CATALYST DETERIORATION DETERMINATION SYSTEM - The determination of deterioration of a NOx storage reduction catalyst ( | 12-19-2013 |
20140003999 | CATALYST DETERIORATION DETERMINATION SYSTEM | 01-02-2014 |
20140110519 | SHEET WINDING DEVICE FOR VEHICLE - A sheet winding device for vehicle includes a winding shaft, a sheet, a torsion coil spring and a soundproofing tube. The winding shaft is axially supported on a vehicle body. The torsion coil spring rotationally biases the winding shaft in a winding direction of the sheet and elastically deforms such that a meandering is increased relative to an axial direction of the torsion coil spring in response to the rotation of the winding shaft. The soundproofing tube is arranged between the winding shaft and the torsion coil spring and includes at least one slit formed by cutting out at least one part on a circumference of the soundproofing tube over an entire length of the soundproofing tube in the axial direction. | 04-24-2014 |
