ドル状態判別装置。 An idle sensor is used in an internal combustion engine that opens a throttle valve depending on the operating state of the load to change the idle speed, and detects the idle state from the opening degree of the throttle valve. control means for stopping the discrimination based on the data and switching to the discrimination based on the data stored in advance;
An idle state determination device for an internal combustion engine, comprising: delay means for delaying the switching timing by a predetermined period of time from when the load stops.
