PROBLEM TO BE SOLVED: To provide an internal combustion engine capable of preventing/suppressing the corrosion of a nozzle injection hole by increasing the heat quantity of a cylinder head.SOLUTION: An internal combustion engine 100 includes an injector 107 having a variable injection hole nozzle 130 in which injection holes 130a, 130b are provided, and an ECU 150 for functioning as a determination part and a control part. When determining that corrosion occurs in an injection hole H, the ECU 150 controls the rate of fuel injection from a first injection hole 131a to make the degree of the use of the first injection hole 131a higher than when determining that the corrosion does not occur in the injection hole H, until a head heat quantity Q is greater than a predetermined quantity Q. Fuel injection from the first injection hole 131a is set to be directed toward the further side of a cylinder head 101a than fuel injection from a second injection hole 131b. |
