HIGHER FUEL EFFICIENCY FOR EMD DIESEL LOCOMOTIVES

The energy crunch has created penalties in fuel costs whereby railroads are experiencing the highest fuel bills in their history. Electro-Motive Division of General Motors Corporation, as a major manufacturer of diesel-electric locomotives, is dedicated to increasing the fuel efficiency of its diesel locomotives. Since the introduction of the "40 Dash Two" Series of locomotives in 1972, EMD has made significant advances in improving locomotive fuel efficiency via basic design changes to the Model 645 diesel engine to improve its thermal efficiency and also by changes in the locomotive support systems to reduce parasitic losses. Future locomotive models will continue this trend in improved fuel efficiency through further advances in the design of engine components and support systems.
