<P>PROBLEM TO BE SOLVED: To suppress consumption energy for promoting the vaporization of droplets, in an exhaust emission control device for supplying reducing agent of liquid phase to a catalyst device installed in an exhaust passage. <P>SOLUTION: A cyclone collector 16 is disposed in an exhaust passage 12. The cyclone collector 16 is a means for collecting a predetermined mass or more of liquid-phase particles of fuel as reducing agent. The exhaust passage 12 is disposed downstream of an adding injector 14 as a supply means and upstream of the catalyst device 30. Since the cyclone collector 16 as a collection means is disposed in the exhaust passage 12, the vaporization of the reducing agent is promoted by the heat of the exhaust gas, the consumption energy for promoting vaporization of droplets is suppressed. <P>COPYRIGHT: (C)2007,JPO&INPIT |
