  • Fuel supply apparatus for an internal combustion engine
    Publication number: 20020139111
    Abstract: A gasoline in a material fuel tank is separated into a high-RON fuel having a higher octane value than the material fuel and a low-RON fuel having a lower octane value than the material fuel, by a separator device equipped with a separation membrane. Using a fuel switching mechanism, one or both of the high-RON fuel and the low-RON fuel are supplied to the engine in accordance with the state of operation of the engine. As the octane value of a fuel can be changed in accordance with the engine operation state, the state of combustion in the engine improves, so that both an increase in engine output and an improvement in an exhaust property can be achieved.
