This study examines evaporative emissions and canister performance as a function of methanol usage and fuel volatility. A total of six different fuels are examined: three methanol blends and three gasoline fuels. Each methanol blend has been specially prepared so that its Reid vapor pressure (RVF) is matched with one of the gasoline fuels. The result is three methanol blend-gasoline fuel pairs having volatilities of 9 psi., 11.2 psi., and 14.4 psi RVP. Evaporative emissions from an automobile tested with these fuels are measured and characterized. In addition to these data, data detailing the composition of fuel tank head-space and canister weight gain and loss fluctuations are also presented.
