Abstract
Commingling of fuels containing various concentrations of ethanol can occur in a vehicle fuel tank. It was not possible to estimate the RVPs of commingled ethanol containing fuels because they form complex non-ideal solutions. A nomograph and an equation were developed using the theory and experimental data for estimating the RVP of a commingled ethanol fuel blend from the RVPs of two base fuels containing any amounts of ethanol. The model is also useful for general purpose estimation of vapor pressures of ethanol/gasoline blends such as seasonal blending of E85 fuels with the right vapor pressure gasoline and the right amount of ethanol to meet the seasonal fuel vapor pressure requirement.
