Tests were conducted to determine effects of ethanol-gasoline blends on emissions, fuel economy, and driveability of fourteen 1980 model-year vehicles representing several emission-control technologies. Two types of blends were prepared: in one blend, the effect of ethanol addition on volatility was not counterbalanced; in the other two, it was counterbalanced by volatility adjustment. Ethanol in gasoline resulted in a statistically significant decrease in exhaust CO emissions; increases in exhaust NO/sub x/, aldehyde, and ethanol emissions; increases in organic and ethanol evaporative emissions; poorer driveability; more vapor lock; and improved energy economy (mi/MBtu). Changes in exhaust organic emissions and fuel economy were not significant for the vehicle fleet as a whole. Statistically significant effects of volatility adjustment were found, but these were smaller than the effects of ethanol addition.
