This project was sponsored by Dennis Smith at the U.S. Department of Energy Vehicle Technologies Program under the Clean Cities program.


The goal of this project is to make a high-level compatibility assessment of legacy vehicle fuel system components to intermediate blends of gasoline and ethanol, specifically focusing on vehicles produced in the mid-1990s. These vehicles were designed before ethanol was a common gasoline component; therefore, their tolerance to higher concentrations of ethanol is not certain.
