摘要： An air-fuel ratio control apparatus according to an embodiment of the present invention, controls an air-fuel ratio (air-fuel ratio of an engine) of a mixture supplied to the engine, based on an output value of the downstream-side air-fuel ratio sensor disposed downstream of a catalyst. That is, the air-fuel ratio control apparatus sets the air-fuel ratio of the engine at a rich air-fuel ratio when the output Voxs is smaller than a reference value VREF (when a rich request is occurring). The air-fuel ratio control apparatus sets the air-fuel ratio of the engine at a lean air-fuel ratio when the output Voxs is larger than a reference value VREF (when a lean request is occurring). The air-fuel ratio control apparatus makes the target value VREF gradually come closer to a reference value VF (stoichiometric air-fuel ratio corresponding value) from a certain value, when the output value Voxs deviates greatly from the reference value Vf (points P1-P3).

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.

摘要： The fuel injection apparatus includes: a fuel injector having a leading end that has an internal space in which fuel is accumulated and has a fuel injection port; and an adsorbent, capable of selectively adsorbing an alcohol component in a blended fuel of gasoline and alcohol, disposed in the internal space. The fuel injection apparatus controls an injection amount from the fuel injector such that an air-fuel ratio is a controlled target air-fuel ratio based on an alcohol concentration of a blended fuel supplied to the fuel injector. In this fuel injection apparatus, a fuel pressure is brought to a predetermined high fuel pressure during cold starting of the internal combustion engine. At this time, an adsorbed amount of alcohol on the adsorbent is estimated and any deviation in the air-fuel ratio of the internal combustion engine is corrected based on the adsorbed amount of alcohol.
