The internal combustion engine has developed to the point where it can provide maximum benefits to the consumer with minimum cost to industry. Unfortunately, it has traditionally not been efficient enough in terms of either emissions or fuel economy. This paper examines the relationship between automotive air pollution and fuel economy in terms of existing and proposed technology. In particular it asks whether or not it is possible to meet both air pollution and fuel economy standards simultaneously with minimum cost to the consumer. Federal controls, including the Clean Air Amendments of 1970 and 1977, and the Energy Policy and Conservation Act of 1975, are analyzed against the nature of air pollution and the internal combustion engine (ICE). A number of alternate engine types are also examined. Many of these offer the possibility of increased fuel economy and decreased emissions, but lag far behind the ICE in development and implementation potential. For the immediate future, modifications of the ICE will probably be used to meet legislated standards, with gradual introduction of some alternate engine types. The rate of introduction of these types is dependent on the amount of development and economic feasibility of such an introduction. It is also possible that standards could be met solely by modifications to the ICE. Past the year 2000, the future of the automobile is uncertain, considering dwindling petroleum supplies. /Author/
