A study of exhaust emissions was performed in Westminister, California, to determine the relationship of emissions levels to the maintenance condition of the vehicles. The test fleet consisted of 100 San Francisco area consumer-owner 1975-1976 model-year passenger cars equally represented by the three major U.S. automobile manufacturers. All vehicles were tested using the 1975 Federal Test Procedure. Additional tests included Highway Fuel Economy Tests and several short-cycle tests. Each vehicle was tested initially in the as-received condition. Various stages of restorative maintenance and retesting were then performed in an attempt to bring failing vehicles into compliance with 1975/1976 California standards. Selected vehicles were also subjected to a series of specified maladjustments or disablements in order to evaluate the individual and combined effects of these conditions on emissions and fuel economy.
