A 1981 Datsun 200SX automobile was modified to enable it to operate on either methanol, ethanol, or gasoline. The electronic fuel injection system of the vehicle was modified to provide this multiple fuel capability, with optimum operation on each fuel. Two fuel tanks are used; the existing gasoline tank and an alcohol fuel tank which may contain either methanol or ethanol. Selection of either gasoline or alcohol operation is accomplished electronically by simply throwing a switch inside the car. Selection of the kind of alcohol to be used, either methanol or ethanol, is accomplished by turning a selector value in the engine compartment. Comparative exhaust emissions and fuel economy tests were performed on the vehicle using each of the three fuels. Best energy efficiency and lowest exhaust emission were achieved simultaneously using methanol. Ethanol was second in both categories, and gasoline achieved inferior efficiency and emissions compared to both alcohols. (ERA citation 10:037056)
