The near-term commercial feasibility of a wide range of automotive emission control technologies is investigated. The central issues can best be explained in terms of the emission control characteristics of each technology and their costs, with government established emission control standards viewed as constraints. Emission control technologies that show promise of near-term manufacturability will be identified. The emission characteristics of example vehicle-engine combinations will be listed. The impact of pollution control technology on the economic decisions facing the new car consumer will be discussed. Comparison is limited to real emission data from actual tests of different control technologies applied to vehicles of equivalent size. Examples are developed to show how expenses for each of the vehicle types under study may be converted into an approximate annualized cost of emission control above the baseline 1970 subcompact car. Any exhaust emission standard written so as not to exclude the conventional engine with dual-catalyst emission controls will be attainable by suitable diesel, Wankel, or stratified-charge engines. The results are inclusive when attempting to pinpoint the lowest cost alternative engine technology. Consumers would probably prefer lower first cost over long-run operating economy. Market forces argue for the commercial feasibility of more than one type of emission control technology when the basic cost differences between competing technologies are relatively small. Economic consequences of one emission control technology over another are likely to escape the grasp of the new car consumer. Deliberate promotion of sustained technological competition aimed at the joint reduction of auto exhaust emissions and consumer costs will help assure superior automotive designs in the near future.
