The fuel reforming device feeds a material to a reforming catalyst and produces the reformed gas under a pressure higher than the atmospheric pressure. The fuel reforming device comprises a material supply means for supplying the material to the reforming catalyst, a reforming means having the reforming catalyst, for reforming the material supplied from the material supply means, to produce the reformed gas, and a run control means for controlling the run of the fuel reforming device. The run control means includes a stop mode, in which the drive of the material supply means is stopped to stop the production of the reformed gas, a reform mode, in which the material supply means is driven to produce the reformed gas, and a standby mode, in which the material supply means is driven and in which the temperature of the reforming catalyst is held within a predetermined range while producing the reformed gas as little as possible, so that the standby mode can shift instantly to the reform mode.

The exhaust gas cleaner (10) is for use in purifying the exhaust gas discharged from an internal combustion engine (15) in which fuel is fed under periodical rich or lean conditions and burned. The cleaner (10) comprises: a reforming means (11) which generates a reforming gas comprising hydrogen and carbon monoxide; a means of low-temperature oxidation (12) which contains palladium and which thereby can oxidize and adsorb nitrogen oxides at low temperatures and oxidize the hydrogen and carbon monoxide; and a purifying means (13) which under lean conditions adsorbs nitrogen oxides and which under rich conditions releases the adsorbed nitrogen oxides and removes the released nitrogen oxides with the hydrogen and carbon monoxide present in the channel. By contriving the layout of the reforming means (11), means of low-temperature oxidation (12), and purifying means (13), nitrogen oxides contained in an exhaust gas can be removed in a wide temperature range from a low temperature.

摘要： An exhaust gas purification device for an internal combustion engine, in which a catalyst installed in an exhaust passage is quickly heated to the activation temperature of the catalyst. The exhaust gas purification device has a NOx purification catalyst (33) for adsorbing or occluding NOx in exhaust gas and reducing the NOx, a catalytic converter (31) installed at that position of an exhaust pipe (4) which is upstream of the NOx purification catalyst (33), a fuel reformer (50) installed separately from the exhaust pipe (4), producing a reformed gas, and supplying the reformed gas, as a reducing gas, into the exhaust pipe (4) from an introduction opening (14) formed in that portion of the exhaust pipe (4) which is upstream of the NOx purification catalyst (33) and the catalytic converter (31), and an ECU (40) which, while the exhaust gas air-fuel ratio is being set to be lean, supplies the reducing gas into the exhaust pipe (4) and controls at least one of a throttle valve (9), an EGR valve (13), and a supercharger (8) to regulate the flow rate of the exhaust gas flowing in the exhaust pipe (4).

摘要： An exhaust purification device for an internal combustion engine can achieve high NOx purifying performance independent of operating conditions of the engine. The exhaust purification device has a NOx purification catalyst (33) mounted in an exhaust pipe (4) of the internal combustion engine, adsorbing or occluding NOx in exhaust gas when the exhaust gas air/fuel ratio is made lean, and reducing the adsorbed or occluded NOx when the exhaust gas air/fuel ratio is made rich; a fuel reformer (50) mounted separately from the exhaust pipe (4), reforming fuel to produce a reducing gas containing hydrogen and carbon monoxide, and supplying the reducing gas into that part of the exhaust pipe (4) which is located upstream of the NOx purification catalyst (33); and enriching means for enriching the exhaust gas air/fuel ratio. When one or more of operating conditions are satisfied, the enriching means enriches the air/fuel ratio of mixed gas to be combusted in the engine and causes the fuel reformer (50) to supply the reducing gas into the exhaust pipe (4) to enrich the exhaust gas air/fuel ratio.
