A STUDY OF EXHAUST EMISSIONS FROM 1978-1980 MODEL YEAR THREE WAY CATALYST VEHICLES IN LOS ANGELES

This report presents and summarizes exhaust emission data and other information obtained as a result of the testing and inspection of 350 in-use passenger cars. The test fleet was made up of 1978, 1979 and 1980 automobiles manufactured by Ford, General Motors, Mazda, Saab, Toyota, Volkswagen/Audi and Volvo. Each vehicle was equipped with a three way catalyst control system. They were obtained randomly from private owners in the Los Angeles and Orange County areas. The testing was completed December, 1979. Each vehicle was tested only in as-received condition. The test sequence consisted of the 1975 Federal Test Procedure (exhaust emissions only), a Highway Fuel Economy test, a Two-Speed Idle test, a Federal Three Mode test, and a Loaded Two Mode test. After the initial test sequence, each vehicle was subjected to a thorough underhood inspection.
