Abstract: An intake air amount control system for an internal combustion engine installed in an automotive vehicle has an intake air amount control valve arranged in a bypass passage bypassing a throttle valve arranged in an intake passage of the engine. The intake air amount control valve controls the amount of air supplied to the intake passage at a location downstream of the throttle valve. The intake air amount control valve is controlled in dependence on operatives states of electric devices including an electrically-heated catalyzer which are installed on the vehicle and supplied with electric power by an alternator installed on the vehicle and driven by the engine, when the engine is in a predetermined operating condition. The intake air amount control valve is controlled by the use of a correction amount dependent on an operative state of the electrically-heated catalyzer.

Abstract: An exhaust gas-purifying system is provided for an internal combustion engine for use in a vehicle having an alternator driven by the engine to generate electric power. An electrically-heated catalyzer is arranged in the exhaust system of the engine and connected to the alternator to be electrically heated thereby. A changeover switch is provided for selectively switching the destination of electric power generated by the alternator to the electrically-heated catalyzer and to the electrical equipment. An ECU controls the electric power generated by the alternator, depending upon a direction in which the changeover switch has been switched. The ECU detects abnormality of the changeover switch, and when the abnormality is detected, the electric power generated by the alternator is changed to a value smaller than a value assumed when the changeover switch is normal.
