The fuel injection apparatus for the internal combustion engine 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 host retains a fallback slow-path processing capability. The signals can be provided, for example, by two microphone pairs, one pair of microphones located in a user’s left ear and the second pair of microphones located in the user’s right ear. The first fastener is arranged in the pivotable head for coupling a display unit. In particular, the device will not break down at the bottom of the base-collector junction which is the weak spot for conventional devices.
