Alcohol-gasoline blends have attracted considerable attention for a variety of reasons, including their higher evaporative emissions compared with gasolines. To better understand the reasons for higher evaporative emissions with blends and to determine if blends with similar volatility (closely matched Reid vapor pressure and distillation temperatures) to gasoline would have equivalent evaporative emissions, experimental and modelling studies were undertaken. Evaporative emissions with alcohol-gasoline blends were nearly equal to or slightly lower than corresponding emissions with gasolines of similar volatility characteristics.
