Abstract
A fuel injection control apparatus for an engine which carried out a fuel injection control according to a speed density system which estimates an intake air amount from detected engine rotational speed value and intake pipe pressure value to decide a fuel injection amount, the control apparatus preventing an air fuel ratio from becoming lean due to clogging of an air cleaner, by calculating an intake pipe pressure differential pressure value between an intake pipe pressure average value and an intake pipe pressure minimum value which are continuously detected, and by correcting the fuel injection amount according to a predetermined procedure while using the differential pressure value of the intake pipe pressure.
