Abstract
It is important to know how heavy-duty diesel vehicles affect the air quality in the United States. Twenty-five heavy-duty diesel vehicles in the CRC E55/59 Phase I study were tested on the Urban Dynamometer Driving Schedule (UDDS), AC50/80 and the Heavy Heavy-Duty Diesel Truck (HHDDT) Schedule using the West Virginia University Transportable Emissions Laboratory (TransLab). Every vehicle in the CRC E55/59 Phase I study was tested at 30,000 lbs. (Unladen) and 56,000 lbs. (Laden) on the HHDDT, except for one tanker truck that was tested at 45,000 lbs (Laden). Also, the first thirteen vehicles in the study were tested on Long Idle Modes (2 Idle Modes combined) and on the Long Creep Mode (4 Creep Modes combined).;All twenty-five heavy-duty diesel vehicles were examined in relation to engine model year to understand how emissions production from diesel vehicles has improved in recent years. Emissions of CO, CO2, HC, NO X and PM were sampled during each test run for every diesel vehicle in the CRC E55/59 Phase I study. (Abstract shortened by UMI.).
