The Chrysler Cleaner Air System for 1970 700151

For the 1970 model passenger cars and light trucks, the Federal and California exhaust emission standards were reduced to 2.2 grams per mile hydrocarbon and 23 grams per mile carbon monoxide. This represents a reduction of approximately 33%.
This paper presents the development of the significant features of the Chrysler Cleaner Air System of exhaust emission control for 1970. Included in this development are modifications in the engine, carburetor, ignition system, and other related components. Through these modifications and by optimizing the calibration of the engine operating parameters, the new exhaust emission standards were successfully met.
