ABSTRACT:
Fuel amount control apparatus arranged to determine the amount of fuel to be fed to respective cylinder so that the scattering in torque generation throughout the cylinders is suppressed. Correction amounts are first obtained during idling, and these correction amounts are then modified using at least one engine parameter so that they can be used not only in idle state but also other operating states. To this end, a correction factor is computed using engine speed or the like so as to modify the correction amounts thereby. As a result, a basic fuel amount is corrected by correction factors provided for respective cylinders where the correction factors are further modified to be suitable for any engine operating conditions, providing smooth rotation without uncomfortable vibrations.
