PROBLEM TO BE SOLVED: To materialize rail pressure control having higher reliability and safety by surely suppressing and reducing an influence of a dynamic viscosity on the rail pressure control as compared to the conventional practice.SOLUTION: An injector control amount correction portion for correcting an injector control amount being an amount of fuel used for opening and closing valves inside fuel injection valves 2-1 to 2-n is calculated based on a temperature and a dynamic viscosity of fuel, and using the calculated injector control amount correction portion, the injector control amount is corrected. Meanwhile, a leak amount correction portion for correcting a leak amount being an amount of fuel leaking from the fuel injection valves 2-1 to 2-n is calculated based on the temperature and the dynamic viscosity of the fuel, and by using the calculated leak amount correction portion, the leak amount is corrected and, thereby, an influence of the dynamic viscosity on fuel injection can be surely suppressed and reduced. |
