Abstract
There is disclosed a fuel injection control system for an in-cylinder fuel injection internal combustion engine, which is capable of properly determining a fuel injection time period such that the fuel injection time period reflects a fuel pressure and a deposition of fuel, thereby controlling the amount of fuel to be actually injected. Operating conditions of the engine are detected, and a required fuel amount is determined based on the detected operating conditions. At the same time, a deposited-fuel amount, i.e. an amount of fuel deposited in a combustion chamber, is determined based on the detected operating conditions, and the required fuel amount is corrected according to the determined deposited-fuel amount. Further, a fuel pressure of fuel to be injected into the cylinder is detected, and the fuel injection time period is determined by correcting the corrected required fuel amount according to the detected fuel pressure.
