Vapor pressures of mixtures of gasolines and gasoline-alcohol blends

OSTI ID:6875740
An investigation was conducted to determine the change in Reid vapor pressure (RVP) which results when gasoline and various gasoline-alcohol blends are mixed. Such mixing occurs in vehicle fuel tanks when a motorist buys gasolines and blends alternately. When mixing a gasoline with a gasoline-alcohol blend of the same RVP, the resulting mixture always had a higher RVP. The results of this study suggest that the presence of both gasolines and blends in the marketplace can lead to higher in-use evaporative emissions from vehicles, even if the blends meet the same volatility standards as gasoline.
