The growth in population (Fig. 1) plus the growth in energy consumption per person(1) have combined together to give dramatic increases in both air and water pollution problems. The automotive vehicle has been a significant contributor to air pollution on a total mass basis (Fig. 2), although its contribution is considerably smaller if the toxicity of emissions as well as the quantity of emissions is considered (Fig. 3).(2) Thus, the purpose of this paper is to first of all indicate why certain exhaust constituents from automotive vehicles are considered as pollutants, to describe how these pollutants are formed in automotive vehicle operation, and finally, to describe control techniques being used and considered. As indicated in the title, the paper is intended to educate by organizing and systematizing existing information rather than presenting primarily new information.
