The primary objective of this study was to determine the most effective method of reducing emissions of oxides of nitrogen from a two-cylinder version of an EMD series 567C locomotive engine. The NOx control techniques selected for use in this study included (1) change in fuel injector design, (2) variation in injection timing from the standard setting, (3) water induction, (4) air box bleed, (5) exhaust gas recirculation. Continuous measurements of unburned HC, CO, NOx and smoke opacity were made as the test engine was operated through a test cycle based on speed and load points characteristic of actual locomotive operation. Results of these tests are discussed.
