Abstract A comprehensive study of emissions from light duty vehicles was performed in six cities of the United States to determine the contribution to atmospheric pollution by the vehicle population. Over 1,000 vehicles of the 1957 through 1971 model years were tested to determine the levels of hydrocarbon, carbon monoxide, carbon dioxide and oxides of nitrogen exhaust emissions. Evaporative emission tests using the SHED technique were performed on a subsample of vehicles in Los Angeles and Denver. Comprehensive statistical analyses of emission results by city, manufacturer, make, model year and engine class are presented. (Author)
