SYSTEM AND METHOD OF OPTIMIZING FUEL INJECTION TIMING IN A LOCOMOTIVE ENGINE

摘要

Systems and methods for reducing engine emissions in a locomotive are presented. In an embodiment, a fuel injector or a fuel injection pump of a fuel injection mechanism includes a plunger (110) with an upper helix (180) whose angle changes between points on the plunger (110) that correspond to an idle throttle position and a full throttle position. As such, injection timing is optimized, and engine emissions are reduced.
