ABSTRACT:
The fuel injection quantity required for maintaining the air-fuel ratio of the mixture supplied to each cylinder of an engine at a desired value is determined by a deposition rate X at which injected fuel deposits and forms a film mass on an intake manifold wall of the engine and a vaporization rate 1/.tau. at which the film mass vaporizes from the manifold wall, a current film mass quantity M.sub.f determined from the calculated X and l/.tau. and the fuel quantity by the preceding injection, a desired fuel quantity Q.sub.a /(A/F) to be supplied air-fuel ratio A/F in accordance with the following equation ##EQU1## an air-fuel ratio feedback correction factor .gamma. aiming at a stoichiometric air-fuel ratio based on a signal generated by an O.sub.2 sensor is calculated and an actual quantity of fuel corresponding to G.sub.f .multidot..gamma. is injected. A film mass quantity in a current computing cycle is based on the film mass quantity calculated during the previous computing cycle.
