EMISSION CONTROL AND FUEL ECONOMY

In selecting the best system for emission control, the largest differential cost factor is normally fuel economy. The authors conclude that for the 1975 U.S. interim standards, the combination of thermal systems and high compression ratios (with leaded fuels) is almost equivalent to the use of catalytic systems at lower compression ratios. However, for more stringent standards, the catalytic systems are more efficient. If catalytic systems are used widely, there is a fuel economy incentive for increasing vehicle compression ratios slightly and using higher octane unleaded fuels.
