PROBLEM TO BE SOLVED: To provide a fuel injection control device capable of keeping control properties of output of an internal combustion engine high even in a case that a plurality of times of fuel injection are performed in one combustion cycle. SOLUTION: Predicted value of concentration of oxygen discharged from a combustion chamber is calculated based on demand injection quantity, opening of an EGR valve and air quantity in a step S22. Then, slippage quantity between the demand injection quantity and actual injection quantity is calculated based on difference between the predicted value and a detection value in a step S 26. Then, a learning value is calculated by dividing the slippage quantity by number of times of injection in multiple stage injection control in a step S28. COPYRIGHT: (C)2008,JPO&INPIT
