摘要： PURPOSE:To perform the reliable starting of an engine by providing a power source for an electric heating catalyst independently from a power source for controlling an engine and controlling an energizing amount so that a detected electric heating catalyst temperature is adjusted to a value approximately equal to a set temperature, in an electric heating catalyst control device for an automobile engine. CONSTITUTION:Through turning ON of a key switch 13, a control circuit 5 performs feedback control by means of a set catalyst temperature and the detected temperature of a temperature sensor 6 installed to a front catalyst 2. Namely, duty control is made on the base of a transistor 11 so that the temperature of the front catalyst 2 is adjusted to a value approximately equal to a set temperature to control energization to the front catalyst 2. An independent battery 15 is arranged as a power source to the front catalyst 2, a charger 14 is provided, and a voltage is set to a value, for example, 24V, equal to or higher than that of a battery 4 for an engine. The charger 14 employs an alternator different from an alternator for controlling an engine. This constitution prevents lowering of capacity of the battery for engine and causes execution of a reliable starting.
