ABSTRACT:
A system and method for controlling quantity of fuel injected to an internal combustion engine are disclosed in which a characteristic having a correlation to part of fuel supply quantity from an injector which has been supplied toward a wall surface of an intake air passage of the engine has been adhered onto the wall surface and will be brought away from the wall surface into a combustion chamber during a suction stroke at the present fuel injection timing is derived so that a correction quantity for a quantity of injected fuel is calculated on the basis of the derived characteristic. Therefore, an air-fuel mixture ratio when the engine falls in a transient state is not deviated from a target air-fuel mixture ratio so that an exhaust gas emission characteristic can be improved.
