Conclusion and Outlook*

Abstract

Since the first introduction of exhaust catalysts in the 1970s, in the United States, pollution from vehicles has been reduced by 99% compared to the level before the introduction of catalytic exhaust control. A major remaining challenge for the automotive industry is the lowering of fuel consumption and CO 2 emissions. This is also a challenge for catalyst development since the most fuel-efficient engines operate with excess air and provide significantly lower exhaust gas temperatures. Automotive catalysts were more or less add-ons to vehicles. State-of-theart emission control technologies are significantly more complex. Automotive emission control has evolved into an interdisciplinary field in which technological and commercial success can only be achieved in an integrated development process with close cooperation of combustion specialists, engine control engineers, and catalysis experts.
