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.
