Title:
SYSTEM AND METHOD OF OPTIMIZING FUEL INJECTION TIMING IN A LOCOMOTIVE ENGINE
Document Type and Number:
WIPO Patent Application WO2004059159
Kind Code:
B1
Abstract:
Systems and methods for reducing engine emissions in a locomotive are presented. A fuel injector or a fuel injection pump of a fuel injection mechanism includes a plunger with an upper helix whose angle changes between points on the plunger that correspond to an idle throttle position and a full throttle position. As such, injection timing is optimized, and engine emissions are reduced.
