Abstract
In the last 20 years, automotive engineers in the United States have made considerable progress in emission control. Hydrocarbons, carbon monoxide and nitrogen oxides have been reduced substantially. Despite this, new legislation passed in 1970 requires an additional reduction below the present levels by 1975–1976, and this lecture discusses this new engineering challenge.
General Motors’ latest progress with alternative power plants and their relative feasibility in both the near and more distant future is discussed.
