Steady-state gaseous and particulate emissions data are presented from two 12-cylinder diesel locomotive engines. The two laboratory engines, a EMD 645E3B and a GE 7FDL, are rated at 1860 kW (2500 hp) and are representative of the majority of the locomotive fleet in North America. Each engine was tested for total hydrocarbons (HC), carbon monoxide (CO), oxides of nitrogen (NOx), and particulate. Emissions were measured at all steady-state operating conditions that make up the eight discrete locomotive throttle notch positions, plus idle, low idle, and dynamic brake. Emissions are reported for each engine with two different diesel fuels: a baseline diesel fuel with a sulfur content of 0.33 weight percent, and a commercially available low-sulfur diesel fuel with a sulfur content of 0.01 weight percent.
