Abstract
In an exhaust emission control apparatus of an internal combustion engine with an intake air flow control valve controlling intake air flow exerting an influence upon a behavior of fuel injected from a fuel injector, and an electric valve actuator electrically operated by a storage battery serving as an electric power source to drive the intake air flow control valve, an electronic control unit is provided for controlling an opening of the intake air flow control valve. The control unit controls the opening of the intake air flow control valve to a predetermined intermediate valve opening by the valve actuator during an engine stopping period. Also, the control unit holds the intake air flow control valve at the predetermined intermediate valve opening to which the intake air flow control valve has been driven in advance during the engine stopping period, by inhibiting operation of the valve actuator during an engine-cranking operating mode at a starting period.
