EXHAUST EMISSION CONTROL DEVICE |
摘要 |
Fuel added to exhaust gas is uniformly afforded to catalytic surfaces of a NOx-adsorption reduction catalyst so that overall regeneration of the NOx-adsorption reduction catalyst proceeds efficiently. The invention is directed to an exhaust emission control device with the NOx-adsorption reduction catalyst incorporated in an exhaust pipe (exhaust flow passage) for guidance of the exhaust gas 9 from an engine 1 and with an fuel addition device (fuel addition means) 13 arranged for addition of fuel as a reducing agent to the exhaust pipe (exhaust flow passage) 11 upstream of the reduction catalyst 12 (exhaust flow passage) 11, a dispersion plate 15 being arranged between a position of adding the fuel by the fuel addition device 13 and the NOx-adsorption reduction catalyst 12 for dispersing the exhaust gas 9 to stimulate dispersion of the added fuel. |
