Fuel Economy Trends and Catalytic Devices 740594

In 1968, a major oil company cancelled its annual automobile economy run after sponsoring it for 18 consecutive years -presumably due to lack of interest from the public and the press. Almost coincident with that cancellation was the beginning of production automobile exhaust emission control on a national basis and a downward inflection in the historic trend of automobile fuel economy. In contrast, the past year has seen a major revival of interest, by both the public and the press, in fuel economy. In the next few weeks, the nation will be introduced to a new direction in automotive exhaust emission control which will profoundly affect the fuel economy trend. Perhaps equally, or even more important, the next few months are expected to see major national decisions on future automobile emission control which will likely have a significant influence on the direction taken by automobile fuel economy a few years hence. It, therefore, appears most appropriate at this time to examine the present trend in automotive fuel economy as influenced by control of air pollutant emissions.
