Title:
ガソリンを高オクタン価燃料と低オクタン価燃料とに分離する膜を有する内燃機関用燃料供給装置
Document Type and Number:
Japanese Patent JP2004522039
Kind Code:
A
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.
