The purpose of the test program is to improve the existing conversion procedures for relating engine dynamometer tests in the laboratory to actual on-road emissions and to evaluate new modal approaches to estimate these emissions. The objectives of this project are to: (1) define on-road emissions from HDDVs; (2) assess agreement among engine and chassis dynamometers and on-road emission factors; (3) evaluate current conversion factors for dynamometer data and develop appropriate ones if needed; and (4) develop a modal emissions model that relates highway facility type (including grade) to speeds/accelerations of the vehicle, loaded weight, power demand on the vehicle, and emissions of NOx, CO, and VOCs.
