<p><P>PROBLEM TO BE SOLVED: To provide an exhaust emission control device for an internal combustion engine for effectively reducing fuel consumption for desorption of soluble organic component adsorbed by an exhaust system member. <P>SOLUTION: An electronic control unit 28 adds unburned fuel to an exhaust system for burning and removing SOF adhering on the exhaust system member of a diesel engine under a condition where the engine is in idling operation during or after vehicle deceleration during which exhaust gas flow rate of the diesel engine reduces. Consequently, a quantity of unburned fuel to be added to exhaust gas required for raising temperature of the exhaust gas and a catalyst to temperature at which SOF is burned is reduced, and fuel consumption for removing SOF is effectively reduced. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
