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. Their paper was published online 21 May in the ACS journal Energy & Fuels. specify allowable vapor pressures depending upon the type of fuel and ethanol content, geographic location, and season.
