数制御装置。 A feedback amount is set according to the deviation between the auxiliary air amount control means that controls the amount of auxiliary air supplied to the engine and a target value of the idle speed, and the control amount of the auxiliary air amount control means is increased or decreased based on this feedback amount. and feedback control means for feedback controlling the idle rotation speed to the target value,
The idle speed control device for an internal combustion engine performs feedback control of the idle speed immediately after starting, and includes a start switch ON time measuring means for measuring the ON time of the start switch, and a feedback amount corresponding to the deviation immediately after starting. What is claimed is: 1. An idle speed control device for an internal combustion engine, comprising: feedback correction means for correcting based on time.
