Published Journal Article
Description:
The paper examines one aspect of motor vehicle emissions behavior; i.e. emissions due to engine power enrichment, a factor not well represented in existing models. Database reflecting 46 instrumented vehicles was used to analyze the importance of enrichment emissions to overall vehicle trip emissions records, while relating these emissions to velocity-acceleration characteristics. The paper concludes that enrichment emissions can contribute significantly to overall vehicle emissions. Also, it discusses policy implications of these results on current public policy and emissions model development. (NOTE: The Clean Air Act Amendments of 1990 place much importance on the use of transportation controls to meet air quality standards in non-attainment areas. Inherent in the approach to estimating the beneficial impacts of such transportation measures is an estimation of current levels of emissions (the emissions inventory), followed by a determination of changes in emissions that would occur, given changes in the operation and use of the transportation system.)
