The throttle operation is performed after an internal combustion engine is started. Then, the temperature of a catalyst is obtained based on a signal output from a temperature sensor fitted to the catalyst (step 200). It is then determined whether the temperature obtained is equal to or higher than the activation temperature (step 202). If it is determined that the temperature of the catalyst has not reached the activation temperature, the throttle operation continues (step 204). On the other hand, if it is determined that the temperature of the catalyst is equal to or higher than the activation temperature, the non-throttle operation is performed instead of the throttle operation (step 206). |
