Emission Controls and Fuel Economy of Seven 1973 Vehicles.
For Reference Only At Bureau Libraries :12 pages
This report is a summary of emissions and fuel economy attainable by simple disconnection of the exhaust gas recirculation system and other very minor ignition system modifications on seven 1973 automobiles. The vehicles are considered standard to heavy cars. The average fuel economy change on modification was an increase in miles per gallon of 9 percent with a range of 4 to 14 percent. The CO emissions decreased about 2 percent, the hydrocarbon emissions were up 30 percent, and the nor emissions up 96 percent. An Environmental Protection Agency study released in January 1974 gave similar results for 10 cars covering a much wider range of vehicle sizes.
