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. When more than one alcohol is added to gasoline, it is possible to offset the RVP changes and obtain a blend with a RVP equal to that of the base gasoline. Resources. Click to enlarge.
