This report presents the results of several specific items of analysis conducted on heavy-duty vehicle data generated from two EPA projects. The purpose of the analysis was to provide information on the relationship between engine dynamometer fuel consumption and emissions and fuel consumption and emissions of trucks in actual use. Two separate tasks are covered. In the first task, ten specific items of analysis were performed on the gasoline-powered and diesel-powered truck fuel consumption and emissions data generated under the title 'Study of Emissions from Heavy-Duty Vehicles'. In the second task, the data from CRC Project CAPE-21-71, 'Truck Driving Pattern and Use Survey' were utilized to attempt to develop modal coefficients for both the 9-mode heavy-duty gasoline and 13-mode heavy-duty diesel emissions tests that would correlate the 9 and 13-mode BSFC values with fuel economy of trucks in actual use. This latter attempt was largely unsuccessful.
