The New York State Department of Environmental Conservation (DEC) and Environment Canada have jointly participated along with partners the New York City Metropolitan Transit Agency (MTA); Johnson Matthey, Environmental Catalysts & Technologies; Equilon Enterprises, LLC and Corning, Inc. in a project to evaluate the effect of various combinations of fuels and aftertreatment configurations on diesel emissions. Emissions measurements were performed during engine dynamometer testing of an International DT 466E heavy-duty diesel engine. Fuels tested in the study were Diesel Fuel 1 and 2, low sulfur diesel (150 ppm), two ultralow sulfur fuels (<30 ppm), Fischer-Tropsch, Biodiesel, PuriNOx™ and two Ethanol-Diesel blends. Configurations tested were: engine out, and diesel oxidation catalyst, continuously regenerating diesel filter, and exhaust gas recirculation aftertreatment. In general, the use of more aggressive aftertreatment (ie.
