Abstract
In a catalytic converter operating method according to the present invention, a heater is energized at a predetermined power level or above and thereby heated substantially concurrently with the operation of an engine. During the heating, an oxidizing gas is introduced into the catalytic converter. When the temperature of the heater exceeds a value at which a main catalyst of the catalytic converter or a light-off catalyst carried on the heater functions, the power level is reduced by an output adjuster and supply of the oxidizing gas is suspended.
