The primary objective of this study was to quantify and predict the levels of Federally regulated exhaust emissions from in-use automotive vehicles in the 1975-1985 time period. Input data sources included the EPA Emission Factor Surveillance Program from 1977 through 1980, the California Air Resources Board, and major automotive manufacturers. Regression, failure analyses, and sources-of-variability analyses were employed. Major current/projected emission control technologies were identified and evaluated with respect to normal function and impact of malperformances. Fuel-switching, i.e., misfueling, behavior was analyzed and a model based on available data was formulated and exercised. Vehicle inspection/maintenance (I/M) programs as a strategy for improving in-use emissions performance was assessed. Evaporative emissions and emissions-fuel economy-cost interrelationships were briefly explored.
