数制御装置。 In an engine idle speed control device configured to supply a predetermined amount of auxiliary intake air in addition to the intake air required to maintain a target idle speed immediately after engine startup, the engine speed is detected at the engine speed. The engine includes a detection means and an intake air amount detection means for detecting the amount of intake air, and controls the rotation speed to converge to the target rotation speed immediately after starting according to the difference between a preset target rotation speed and the actual rotation speed. The engine is configured to simultaneously perform rotation speed feedback control to control the intake air amount and intake air amount feedback control to control the intake air amount to converge to the target intake air amount according to the difference between a preset target intake amount and the actual intake air amount. An engine idle speed control device characterized by:
