Abstract
Exhaust emissions from heavy duty gasoline-powered vehicles have been studied in detail, under NAPCA support, at South west Research Institute. The principal exhaust emissions studied were carbon monoxide, hydrocarbons, and oxides of nitrogen. A broad variety of vehicles was tested with three variable speed experimental procedures using chassis dynamometers to simulate actual road operations. Approximately 150 trucks and buses of all weight classes were investigated to determine the ability of each vehicle to perform with the respective experimental cycle, each vehicle’s contribution of contaminants on a mass basis per mile driven, and the applicability of these cyclic test procedures for federal testing.
