The objective of the project was to thoroughly characterize and quantify the criteria and toxic-pollutant emissions from two different types of trap-equipped light-duty diesel vehicles. These vehicles included a 1986 Mercedes-Benz 300 SDL, which utilizes a catalyzed trap system, and a prototype Volkswagen, which utilizes an additive trap system (organometallic iron additive). Exhaust emissions from the two vehicles were evaluated as to driving cycle, presence of traps, engine condition, trap condition and fuel aromatic content. In addition to the currently regulated emissions (HC, CO, NOx and particulate matter), a number of unregulated emissions were measured, including aldehydes, benzene, PAHs, metals and trace elements, and 1,3-butadiene. Particulate samples were also analyzed for mutagenic activity using the Ames test. In general, the vehicles produced lower hydrocarbon emissions, higher carbon monoxide emissions, and lower fuel economy when the traps were installed in the vehicles.
