There is provided an internal combustion engine that uses a blended fuel consisting of hydrocarbon and alcohol, and can efficiently operate relative to a wide range of required load. The internal combustion engine includes: intake portsandand two injectorsand. The injectors include a first injectorthat injects a hydrocarbon fuel and a second injectorthat injects an alcohol fuel. An optimum combustion mode is selected according to an operation state, and the ratio of the alcohol is properly adjusted according to the combustion mode. The intake ports includes a first intake portthat guides the hydrocarbon fuel to an inner peripheral portion of a combustion chamber, and a second intake portthat guides the alcohol fuel to an outer peripheral portion of the combustion chamber to control octane number distribution in a cylinder. The internal combustion engine further includes separating meansfor adding water to a blended fuel consisting of alcohol and hydrocarbon to separate into the alcohol fuel consisting of the alcohol and the water and the hydrocarbon fuel.
