Abstract
An exhaust gas-purifying system for an internal combustion engine includes an alternator driven by the engine. A regulator controls voltage generated by the alternator. An electrically-heated catalyzer is arranged in the exhaust system of the engine and connected to the alternator to be electrically heated by electric power generated by the alternator. An ECU controls the regulator to control the voltage generated by the alternator and supplied to the electrically-heated catalyzer, according to operating conditions of the engine detected by sensors such as an engine coolant temperature sensor and an intake air temperature sensor.
