A study of exhaust emissions from consumer-owned light duty vehicles and light duty trucks was performed in the Los Angeles, California and St. Louis, Missouri areas to determine the emission characteristics of 1967 through 1975 vehicles. Olson Laboratories, Inc., performed exhaust emission tests on 127 vehicles in Los Angeles, California and 510 vehicles in St. Louis, Missouri. Light hydrocarbon and aldehyde measurements were made on ten light duty trucks and thirty-five light duty vehicles in California only. Additional tests conducted included Highway Fuel Economy Tests, keymode tests, special cold start tests with average speeds higher and lower than the standard 1975 Federal Driving Cycle, and modal tests. Vehicles were tested using the 1975 Federal Test Procedure. This allowed the calculation and presentation of test results by both the 1972 and 1975 Federal Test Procedures.
