Project at a Glance
Title: Automotive exhaust emission standards
Principal Investigator / Author(s): Hall, Owen P.
Contract Number: 3-565
Research Program Area: Emissions Monitoring & Control
Topic Areas: Mobile Sources & Fuels
This report discusses the establishment of loaded mode emission standards for the proposed California vehicle inspection and maintenance program. Development of these standards was undertaken in recognition of the role of exhaust emissions in the overall problem of air pollution for the South Coast Air Basin. A cost-effective approach was taken in designing emission standards for the vehicle population. Here, the interactions between modal emissions, mass emissions and vehicle characteristics were evaluated in arriving at a set of preferred emission criteria. Hopefully, these standards will play a key part in improving air quality for the region.
