PROBLEM TO BE SOLVED: To properly control adhesion of condensate to a nozzle hole of a fuel injection valve, even if a sulfur concentration in fuel used for an internal combustion engine is changed.SOLUTION: A control device of an internal combustion engine includes: a fuel injection valve for injecting fuel into the cylinder of the internal combustion engine; a heating means for raising a temperature of the fuel injection valve; a sulfur concentration acquisition means for acquiring the sulfur concentration of the fuel injected into the cylinder by the fuel injection valve; and a control unit for increasing a heating amount of the fuel injection valve by the heating means as the sulfur concentration is raised using the sulfur concentration acquisition means. The heating amount is change according to the sulfur concentration in the fuel, so that the adhesion of condensate to a nozzle hole of a fuel injection valve can properly be controlled even if the sulfur concentration in the fuel used for the internal combustion engine is changed. |
