Environmentally improved motor fuels

摘要

The invention is directed to the use of a combination of ethanol and water in an amount of water between 1 and 10 wt. % on the basis of the weight of the ethanol, in gasoline based motor fuel for keeping the internal and external environment of internal combustion engines cleaner then when using gasoline or ethanol-gasoline blends, having the same ethanol-gasoline ratio.

主权项

1. A method of improving the mileage of a vehicle comprising:
providing a mixture consisting of an ethanol and a water; wherein an amount of water in the ethanol and water mixture is between 1 and 10 wt. % on the basis of the weight of the ethanol in the ethanol and water mixture; providing a combined motor fuel consisting of the ethanol and water mixture and a gasoline without forming a separate liquid layer thereby maintaining a clear and bright specification of the combined motor fuel without blending additives to prevent the occurrence of the separate liquid layer; and burning the combined motor fuel in an internal combustion engine of the vehicle, thereby improving the mileage thereof as compared to burning in the engine a gasoline or a gasoline-ethanol blend not including the water; wherein an amount of ethanol in the combined motor fuel is between 60 and 95 wt. % of the combined motor fuel; wherein the gasoline includes a mixture of a plurality of hydrocarbons, the hydrocarbons in the gasoline boiling in an approximate range of 40 C to 200 C.
