The Mobile Source Emission Factor Model used to estimate the inventory of exhaust and evaporative emissions from on-road motor vehicles is currently being revised by the U.S. Environmental Protection Agency. The framework used in calculating basic exhaust emission rates as a function of accumulated vehicle mileage is described. The revised MOBILE6 is capable of separating the vehicle exhaust emissions into "start" and "running" components, thus enabling more precise descriptions in the model for specific types of driving. The article estimates basic rates for start and running from laboratory test data and from state inspection and maintenance program data. 8 p. This article begins on magazine page 39, PDF page 49.
