Abstract
A fuel injection control apparatus which controls the regular fuel injection amount based on a control law determined in accordance with a fuel dynamic model showing the dynamics of fuel flowing into an engine cylinder using as state variables the amount of fuel sticking to the walls of the intake passage and the amount of fuel evaporating in the intake passage. During deceleration operation, the regular fuel injection is stopped, the control law correction fuel injection amount is determined from the parameter values of the fuel dynamic model, the true values of the rate of fuel sticking to the walls of the intake passage and the rate of remainder of sticking fuel, which are parameters of the fuel dynamic model, are identified based on the amount of fuel injection, the amount of air flowing into the cylinder, and the air-fuel ratio, and the control law is corrected based on the results of the identification.
