Proven. Tough.The 7FDL™ Locomotive Diesel Engine

GE TransportationRail

GE has been designing and building highhorsepower, diesel-electric locomotives forover 30 years. We know the demands placedon engines used in locomotive service betterthan any other engine maker. The proof is inthe 7FDL engine.

The 7FDL Engine is a high-compression, four-stroke,medium-speed, turbo-diesel engine designed specificallyfor locomotive applications. The engine is available in8-cylinder, 12-cylinder and 16-cylinder designs.

It works harder.The 7FDL is proven in operation at altitudes over 3000meters (9850 feet) and temperatures from –50°C to +50°C(-58°F to 120°F). It withstands high cyclic thermal loads, afeature often underestimated by other suppliers who try toadapt their engines to locomotive service.

It goes longer.The 7FDL is capable of running for millions of cost-effectivekilometers. On the 16-cylinder 7FDL engine, for example,overhaul of most components is unnecessary until theengine reaches 26,000 megawatt hours or about eightyears of operation in the most demanding environments.

It runs smarter.A high-capacity turbocharger, efficient combustion systemand electronic fuel injection all combine in the 7FDL engineto offer superior fuel and lube oil consumption capabilitieswhile meeting strict emissions levels. The 7FDL complieswith EPA, Kyoto and UIC standards.

7FDL™ Engines power over 15,000locomotives around the world

Modernize your locomotivesTo increase your railway’s productivity

With locomotives modernized by GE, you get longerservice life, improved performance, higher reliabilityand lower life cycle costs.

The 7FDL engine is the global rail industry’s choice formotive power in modernized locomotives. In nearly 20countries around the world, from Brazil to Kazakhstan,Indonesia to Mongolia, the 7FDL is at the center of GE’slocomotive modernization kit.

High-Performance TurbochargerThe 7FDL engine uses a single free-spinning, exhaust-driven turbochargerthat provides air to the cylinders atapproximately four times atmosphericpressure. Tunnel conditions of more than65°C (150°F) put unusual demands onturbochargers. We worked with GEAircraft Engines to develop a turbo-charger that handles these conditionswhile providing efficiency and reliability.

Welded Head-Liner AssembliesHigher peak firing pressures creategreater stress on the head-to-liner seal.7FDL steel heads and liners have a full-penetration weld that eliminates theupper liner seal. This one-piece designminimizes the effects of heat and stressand prevents leaks. The heads havewelded stainless steel valve seats andvalve rotators to ensure uniform seatingand even wear.

High-Strength PistonsForged steel crowns on the engine’spistons effectively resist high stress andheat conditions. The piston crown isbolted to aluminum-alloy skirts forlighter weight and increased materialrecovery in overhauls. The piston usestwo rings for compression and a thirdring for oil control.

Heavy-Duty CrankshaftThe engine’s one-piece crankshaft isforged from high-quality steel andnitride-hardened for long life. Journalsurfaces are precision ground, and allbearing surfaces are force-fed withlubricating oil. Welded counterweightsensure reliability and reflect the overallsolid engine structure.

Solid Engine BlockThe 7FDL engine block features a sturdyone-piece cast iron construction. Oilpassages are cast into the frame toreduce the potential for leaks. Nocooling water, intake air or exhaustgases touch the frame. Access doors canbe quickly removed for easy inspectionof bearings and other internal crankcasecomponents.

To get the greatest reliability from your 7FDL engines, GErecommends engine overhauls on a regular basis. Overhaulsalso let you take advantage of the latest upgrades.

Since 1962, when we introduced the 7FDL engine, we havebeen continuously improving its design and features. With7FDL engines overhauled and upgraded by GE, customersgain improved reliability and horsepower as well as fuelsavings of up to 15%.
