摘要：
An exhaust gas-purifying device for an internal combustion engine has an adsorbing device arranged in an exhaust passage of the engine for adsorbing unburnt fuel components in exhaust gases from the engine, a catalytic converter arranged in same at a location downstream of the adsorbing device for purifying the exhaust gases, and a heater for electrically heating the catalytic converter. The temperature of the adsorbing device is detected. The heater is controlled to be operated at least on condition that the temperature of the adsorbing device is above a predetermined value. In another form of the invention, the temperature of the catalytic converter is detected. A rate of a rise of the temperature of the catalytic converter is determined. A deterioration state of the adsorbing device is determined based on the rate of the rise of the temperature of the catalytic converter.
