Abstract

Heavy-duty vehicle emissions represent a significant portion of the mobile source emissions inventory. Accurate estimation of their contribution is essential as on-highway and non-road heavy-duty diesel emissions account for at least one third of the oxides of nitrogen (NOx) in the inventory. West Virginia University (WVU) has developed an extensive database of continuous transient gaseous emissions levels from a wide variety of heavy-duty vehicles in field operation. The database was built using WVU Transportable Heavy-Duty Vehicle Emissions Testing Laboratories (THDVETL). Several different transient cycles were utilized for testing including the Central Business District (CBD) schedule.;Several speed correction factors were developed for the three vehicles considered in this analysis. These correction factors can be used to account the variations in the vehicle condition, class and variations in the testing environment. (Abstract shortened by UMI.).
