ABSTRACT:
An exhaust emission control apparatus includes an electrically heatable catalytic converter mounted in an exhaust passage of an internal combustion engine, the catalytic converter having a catalyst for catalytic conversion of exhaust gases from the engine and a heating element for heating the catalyst to accelerate a rate of the catalytic conversion, a power supply for applying power to the heating element, a time setting part for calculating a time period during which power is applied to the heating element, and a control part for controlling application of power from the power supply to the heating element in accordance with the calculated time period in a way that the application of power to the heating element is stopped when the time period since the application of power to the heating element is started has elapsed.
