ABSTRACT:
Disclosed herewith an intake air flow rate control system for an internal combustion engine of an automotive vehicle, in which a pulse duty of a control pulse signal is determined corresponding to a reference engine speed and an actual engine speed, the reference engine speed being determined corresponding to an engine or engine coolant temperature. Varying of the control ratio is limited by a means for controlling the varying rate of the control ratio. In the present system, the control ratio as the sum of feedback rate and open loop rate is limited within a given range. The control ratio is limited within a range 10 to 80% preferably of the pulse duty of the control pulse signal. In the given range, a means for controlling air amount flowing through a bypass passage which bypasses a throttle valve provided in an air intake passage, can respond without causing delay.
