Title: Mobile-source emissions analysis for California. Volume 1. Final report, 1982-85
Abstract: This report, reviews mobile-source emissions from California vehicles and updates the analytical basis for mobile-source-emissions modelling. The research effort addresses the following issues, among others: Identifies the market penetration of emissions-control systems for model years 1975-1982 vehicles and projects the penetration of the systems to 1990; reviews 1975 forward in-use vehicle emissions data to evaluate the performance of individual emissions control systems, including an analysis of failure rates and the emissions impact of specific component failures; analyzes the influence of speed, temperature, misfueling, and inspection/maintenance programs on emission control systems, derives new emission factors for heavy-duty trucks to incorporate the influence of component malfunction; analyzes current technical and regulatory mobile-source-emission issues, as assessment of light-duty vehicle compliance with a 0.4 g/m NOx standard and comments on methanol additive fuel waivers; develops a California I/M credits model; and determines the effect of maintenance practices and fuel quality on transit bus smoke and particulate emissions.
