ABSTRACT:
A fuel supply amount control apparatus improves controllability during engine acceleration and deceleration and immediately after starting the operation of the engine, by enabling the setting of suitable parameters. An evaporation time constant indicating chronological changes in the fuel amount introduced into a cylinder from an intake system of the engine is computed by a predetermined computation equation. During this computation, the computation load is reduced by using an Aquino operator .alpha. and a stroke interval Aquino operator A.alpha. and computation for computing the fuel injection amount is executed at an interval shorter than the interval of two successive fuel injections, e.g., a crank angle of 60.degree.. During computation of the evaporation time constant, the evaporation time constant after full warm-up is corrected based on an average temperature weighted according to an adherence rate of fuel to the intake manifold and intake valve. The intake valve temperature, since it increases according to input heating energy, is estimated from the injected fuel amount.
