Abstract
Average pressure of pressure in an intake passage is calculated. A basic injection quantity is determined by engine speed and the average pressure. On the other hand, estimated pressure is estimated from engine speed and throttle position. A correcting coefficient is obtained from the average pressure and the estimated pressure, and the basic injection quantity is corrected with the correcting coefficient.
