Abstract
In this project, exhaust emissions data were obtained from heavy-duty vehicles operated on chassis dynamometers. A total of 32 vehicles were evaluated, ranging from 7700 kg (17,000 lbs) to 33,000 kg (73,000 lbs) gross vehicle weight (GVW). The vehicles included eighteen gasoline trucks (or truck-tractors), twelve diesel trucks (or truck-tractors) and two diesel buses. The evaluations involved an on-the-road determination for setting dynamometer power and the evaluation on chassis dynamometers of several steady-state, sinusoidal and driving cycle operating conditions. Chassis version nine-mode or thirteen-mode evaluations were conducted as appropriate on all vehicles. Each of the vehicles were evaluated at three different inertia weights and dynamometer road-load settings to simulate an empty vehicle, half payload, and full rated GVW. On two gasoline and two diesel vehicles, the entire emissions test sequence was repeated and determinations were made using alternate driving cycles. Results are summarized by truck for each test method.
