Abstract
The fuel injection apparatus includes: a fuel injector having a leading end portion that has an internal space in which fuel is accumulated and an injection port 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 fuel injection apparatus controls an injection amount from the fuel injector such that an air-fuel ratio of an internal combustion engine is a control target air-fuel ratio based on an alcohol concentration of the blended fuel to be supplied to the fuel injector. In this fuel injection apparatus, a fuel pressure is brought to a predetermined low fuel pressure when a request is issued for desorbing alcohol adsorbed on the adsorbent.
