Vehicle tests showed that evaporative emissions were increased significantly by adding 10% ethanol to gasoline, but were increased less with 15% MTBE in gasoline. The quantity of ethanol or MTBE in evaporative emissions was investigated in laboratory tests. Exhaust HC, CO, and NO/sub x/ emissions from a car without closed-loop fuel control were significantly lower with the ethanol and MTBE fuel blends than with gasoline. For cars equipped with closed-loop carburetors, the absolute differences in exhaust emissions among the fuels were small. Fuel economy and driveability were worse with ethanol and MTBE fuel blends than with gasoline.
