Perspective: US Needs to Transition to Hydrous Ethanol as the Primary Renewable Transportation Fuel

Green Car Congress

AUGUST 30, 2009

The Brazilian experience shows that the presence of small (<10%) amounts of water in the fuel does not in itself cause a greater tendency to misfire in spark ignition engines than a proportionate leaning of the fuel/air mixture would do, provided that the vapor pressure of the hydrated ethanol at the ambient temperature is high enough.

Study of Vapor Pressures of Gasoline-Alcohol Blends Finds That Dual-Alcohol Blends Can Result in RVPs Identical to That of Gasoline

Green Car Congress

RVPs (predicted DVPE) of single- and dual-alcohol blends in gasoline with different relative proportions of ethanol and 1-butanol. Vapor pressure can affect proper cold starting of the engine; vapor lock tendency in older engines without fuel injection; and quality of starting in engines with fuel injection.
