A fuel injection control system of an internal combustion engine driven by an alcohol blended fuel includes a controller that controls the amount of the fuel injected from a fuel injection valve. The controller performs injection amount control after start of cranking, when an alcohol concentration of the alcohol blended fuel is higher than a predetermined concentration, so that the amount of the alcohol blended fuel injected from the fuel injection valve in each fuel injection is controlled to be smaller than an amount of the fuel with which an air-fuel ratio becomes a combustible air-fuel ratio, until an initial explosion occurs. |
