ABSTRACT:
An exhaust emission control apparatus includes an absorbent provided in an upstream portion of an exhaust passage of an engine to absorb hydrocarbon in exhaust gas passed through the exhaust passage at a temperature lower than a predetermined first temperature, the hydrocarbon being desorbed from the absorbent at a temperature higher than the first temperature, a catalytic converter provided in a downstream portion of the exhaust passage to purify hydrocarbon in the exhaust gas when a catalyst of the catalytic converter is active, the catalyst of the catalytic converter being activated at a temperature higher than a predetermined second temperature, the second temperature being higher than the first temperature, and a heating part for heating the catalytic converter to a temperature higher than the second temperature when the engine is in a prescribed starting condition and the absorbent is at a temperature higher than the first temperature, so that the hydrocarbon desorbed from the absorbent in the exhaust passage is purified by the activated catalyst of the catalytic converter.
