ABSTRACT:
A device for controlling the heating of a catalyzer arranged in the exhaust passage of an engine. When the engine is started, the catalyzer is rapidy heated by the heater, and the time for which the power is supplied to the heater is increased as the catalyzer use period becomes longer, to thus increase the temperature of the catalyzer to the activation temperature thereof when the power supply to the heater is stopped regardless of whether the catalyzer is new or has deteriorated.
