Abstract
A method determines a control parameter of an air/fuel ratio of an internal combustion engine having an idle rotational speed control device by which the throttle valve is opened when an electric unit such as the head light or the air conditioner is turned on during the idling of the engine. The air/fuel ratio is controlled to be leaner than a target air fuel ratio when the engine is idling, and controlled to a further leaner side when the electric unit is operating during the idling of the engine.
