Abstract A comprehensive study of exhaust and evaporative emissions from consumer-owned light-duty vehicles was performed in the Los Angeles, California, and St. Louis, Missouri, areas to determine the contribution to atmospheric pollution by 1967 through 1974 model-year vehicles. This study was conducted as part of a total effort to measure the emissions from light-duty vehicles in six cities. Automotive Environmental Systems, Inc. (AESi) performed exhaust emission tests on 180 vehicles in Los Angeles, California and St. Louis, Missouri, as well as SHED (Sealed Housing for Evaporative Determinations) and charcoal canister evaporative emission tests on twenty 1973 model-year vehicles in Los Angeles, California. Model exhaust emission tests were performed on all 1972 through 1974 model-year vehicles. In addition to determining levels of exhaust hydrocarbons, carbon monoxide, carbon dioxide, and oxides of nitrogen exhaust and evaporative emissions, the carbon atom mass balance technique was employed to calculate vehicle fuel economy. Vehicles were tested using the 1975 Federal Test Procedure.

Contents Notes A comprehensive study of exhaust and evaporative emissions from consumer-owned light-duty vehicles was performed in the Los Angeles, California, and St. Louis, Missouri, areas to determine the contribution to atmospheric pollution by 1967 through 1974 model-year vehicles. This study was conducted as part of a total effort to measure the emissions from light-duty vehicles in six cities. Automotive Environmental Systems, Inc. (AESi) performed exhaust emission tests on 180 vehicles in Los Angeles, California, and St. Louis, Missouri, as well as SHED (Sealed Housing for Evaporative Determinations) and charcoal canister evaporative emission tests on twenty 1973 model-year vehicles in Los Angeles, California. Modal exhause emission tests were performed on all 1972 through 1974 model-year vehicles. In addition to determinging levels of exhaust hydrocarbons, carbon monoxide, carbon dioxide, and oxides of nitrogen exhaust and evaporative emissions, the carbon atom mass balance technique was employed to calculate vehicle fueld economy. Vehicles were tested using the 1975 Federal Test Procedure. This allowed calculation and presentation of test results by both the 1972 and 1975 Federal Test Procedures. Instrumentation for measuring exhaust emissions was not modified in accordance with the 1975 Federal Test Procedure. Evaporative emissions were measured using the SHED technique in general accordance with procedures stipulated in SAE Technical Report J171, and the carbon canister technique in general accordance with 37 Federal Register 221.
