ABSTRACT:
A basic injection quantity is determined by engine speed and intake passage pressure. The pressure is estimated from engine speed and throttle position, and changing rate of the estimated pressure is calculated. A correcting quantity is obtained from the changing rate of the estimated pressure. The basic injection quantity is corrected with the correcting quantity.
