ABSTRACT:
Described are a fuel injection control system and method, which are suitable for use in an engine of the system that fuel is injected in an intake pipe. It is the object of these system and method to perform good control on the injection quantity of fuel by precisely grasping evaporation characteristics of the fuel. To achieve this object, a direct feed rate at which a quantity of fuel out of a basic injection quantity is directly fed to a combustion chamber is set and further, an indirect feed quantity of fuel, said fuel being to evaporate from an adhered liquid layer of fuel in an intake port and then to be fed into the combustion chamber, is calculated as the sum of plural partial feed quantities of different evaporation characteristics.
