<P>PROBLEM TO BE SOLVED: To prevent reduction in exhaust emission control performance, even when a low temperature area of hardly activating a catalyst continues over a long time. <P>SOLUTION: A reformer 14 reforms nitrogen monoxide and hydrocarbon included in a toxic component in exhaust gas from an internal combustion engine 10 into water-soluble gas. A water-soluble gas absorbing device 15 separates and removes the toxic component reformed into the water-soluble gas by the reformer 14 from the exhaust gas by being absorbed to an absorbing liquid including water. An exhaust emission control catalyst 16 purifies the toxic component including carbon monoxide passed through the water-soluble gas absorbing device 15 without being absorbed to the absorbing liquid. <P>COPYRIGHT: (C)2013,JPO&INPIT |
