PROBLEM TO BE SOLVED: To prevent fuel injection quantity from an injector from getting less than a permissible lower limit value when fuel injection is shared between a passage injection injector and a cylinder injection injector. SOLUTION: If a passage injection command value Q1 which is a command value of fuel injection quantity of the passage injection injector 6 gets less than a predetermined value B with which the passage injection command value Q1 possibly gets less than the permissible lower limit value min1, a passage injection feed back correction value FAF1 for correcting the command value Q1 is set to 1.0, correction of the passage injection command value Q1 to reduction side by the correction value FAF1 is stopped. If a cylinder injection command value Q2 which is a command value of fuel injection quantity of the cylinder injection injector 7 gets less than a predetermined value A with which the cylinder injection command value Q2 possibly gets less than the permissible lower limit value min2, a cylinder injection feed back correction value FAF2 for correcting the command value Q2 is set to 1.0, correction of the cylinder injection command value Q2 to reduction side by the correction value FAF2 is stopped.
