アイドル時用空気流量制御装置。 Warm-up air flow rate control means that controls the intake air flow rate according to the engine temperature during warm-up operation, and idle speed control that controls the intake air flow rate so that the engine speed during idling operation approaches the target rotation speed. In an air flow rate control device for an internal combustion engine at idle, the device comprises a valve and a first idle control valve that opens to increase the intake air flow rate when an external load increases during idle operation. an air flow insufficient detection means for detecting a state in which the intake air flow obtained by the means and the idle speed control valve is insufficient; 1. An air flow rate control device for an internal combustion engine during idling, characterized by comprising an air flow rate correction control means for increasing and correcting the flow rate.
