FUEL SEPARATION METHOD |
摘要 |
A fuel separation method by which auxiliary fuel is separated from blended gasoline fuel for a flexible fuel vehicle capable of using ethanol-blended gasoline fuel, the method including the following steps (a) and (b): (a) a step in which, when the ethanol concentration is low, the blended gasoline fuel is separated by a polar separating membrane member at a relatively high separation temperature to obtain, at the permeation side of the membrane, a first auxiliary fuel enriched with the aromatic gasoline components and ethanol component, and (b) a step in which, when the ethanol concentration is high, the blended gasoline fuel is separated by a polar separating membrane member at a relatively low second separation temperature to obtain, at the permeation side of the membrane, a second auxiliary fuel enriched with the non-aromatic high-volatile gasoline components. |

1. A fuel separation method for a flexible fuel vehicle capable of using an ethanol-blended gasoline fuel comprising a non-aromatic high-volatile gasoline component, a non-aromatic low-volatile gasoline component, an aromatic gasoline component and an ethanol component, wherein auxiliary fuel is separated from the ethanol-blended gasoline fuel, the fuel separation method comprising the following steps (a) and (b):
(a) when the ethanol concentration of the ethanol-blended gasoline fuel stored in a main fuel tank is within a first ethanol concentration range, the ethanol-blended gasoline fuel is separated with a polar separating membrane member at a first separation temperature to obtain, at the permeation side of the membrane, a first auxiliary fuel that is enriched with the aromatic gasoline component and the ethanol component in comparison with the ethanol-blended gasoline fuel; and (b) when the ethanol concentration of the ethanol-blended gasoline fuel stored in the main fuel tank is within a second ethanol concentration range which is higher than the first ethanol concentration range, the ethanol-blended gasoline fuel is separated with the polar separating membrane member at a second separation temperature which is lower than the first separation temperature to obtain, at the permeation side of the membrane, a second auxiliary fuel that is enriched with the non-aromatic high-volatile gasoline components in comparison with the ethanol-blended gasoline fuel. |
