ABSTRACT:
A fuel injection control system for an internal combustion engine includes an ECU which carries out adherent fuel-dependent correction by calculating an amount of fuel to be injected into the intake passage such that a sum of a direct supply amount of fuel directly drawn into the combustion chamber of the engine without adhering to the wall surface of the intake passage out of a whole amount of fuel injected into the intake passage, and a carried-off amount of fuel carried off the wall surface of the intake passage into the combustion chamber out of fuel adhering to the wall surface of the intake passage is equal to a required fuel amount for the engine. The starting condition of the engine is detected by sensors, and operation of the adherent fuel-dependent correction control is limited during the starting condition of the engine. The carried-off fuel amount is set to a predetermined value, based on at least one operating parameter of the engine when the engine has shifted from the starting condition to the basic operating condition after starting.
