ABSTRACT:
A fuel control system for an engine has a fuel injector which injects fuel into an intake manifold of the engine. A fuel injector controller determines the amount of fuel to be injected from the fuel injector so that the sum of the amount of the direct delivery part of the injected fuel which is directly fed to a combustion chamber of the engine from the injector and the amount of the drawn part fuel which has adhered to the well surface of the intake manifold, evaporates and then flows into the combustion chamber is a target amount of fuel to be actually fed to the combustion chamber and causes the fuel injector to inject the target amount of fuel. When the controller increases the amount of fuel to be injected during acceleration, the amount of part of fuel injected from the injector which part is robbed by the wall surface of the intake manifold near the injector and does not contribute to the air-fuel ratio in intake air fed to the combustion chamber during acceleration is estimated, and the fuel injector controller increases the amount of fuel increase by an amount corresponding to the estimated amount of the part of fuel which is robbed by the wall surface of the intake manifold near the injector and does not contribute to the air-fuel ratio in intake air fed to the combustion chamber.
