ABSTRACT:
An exhaust emission control apparatus for a Diesel engine includes a filter collecting particulates contained in exhaust gases of the Diesel engine and a fuel supply device supplying fuel required for burning the collected particulates. The fuel supply device controls the amount of supplied fuel so that the temperature of the filter can be raised to a level high enough for burning the collected particulates but not so high as to damage the filter itself by the heat applied thereto. A control unit executes the fuel control on the basis of the temperature of the filter and the pressure drop across the filter.
