<P>PROBLEM TO BE SOLVED: To provide an exhaust emission control device easily mounted in a limited space and easily handled, and using a solid reducing agent. <P>SOLUTION: The solid reducing agent 14 for the exhaust emission control device 10 is arrange on the side of the engine 11 of a reduction catalyst 13 in a second exhaust gas passage 24 for allowing a part of exhaust gas delivered from the engine 11 to flow therein. Therefore, at least a part of the exhaust gas delivered from the engine 11 is passed through the solid reducing agent 14 arranged in the second exhaust gas passage 24 and is led to flow into the reduction catalyst 13. The exhaust gas delivered from the engine 11 is passed through the solid reducing agent 14, thereby a reducing agent produced from the solid reducing agent 14 is mixed with the exhaust gas and led to flow into the reduction catalyst 13. Most of the exhaust emission control device 10 including the solid reducing agent 14 is arranged in an exhaust pipe section 12 forming an exhaust passage 16. As a result, the exhaust emission control device is easily mounted in the limited space around the engine 11 and easily handled. <P>COPYRIGHT: (C)2010,JPO&INPIT |
