ABSTRACT:
An exhaust emission control device comprises a temperature sensor for detecting the temperature of exhaust gas directly on the upper-stream side of a diesel particulate filter. An ECU adjusts a compulsive regeneration interval in accordance with a cumulative history of cases in which the exhaust gas temperature detected by means of the temperature sensor continues to be not lower than a value equivalent to a continuous regeneration temperature. The compulsive regeneration interval is adjusted by means of the ECU in accordance with a history of circumstances in which a state for continuous regeneration is realized.
