摘要： A fuel injection apparatus for an internal combustion engine including a fuel injector having a leading end portion that has an internal space in which fuel is stored and an injection nozzle for injecting fuel; and an adsorbent disposed in the internal space, the adsorbent being capable of selectively adsorbing an alcohol component in a blended fuel of gasoline and alcohol. The adsorbent has a characteristic such that an amount of alcohol adsorption is small when a fuel pressure is low and large when the fuel pressure is high. Adsorption of alcohol onto, and desorption of alcohol from, the adsorbent can be controlled by changing the fuel pressure in the internal space.
