The General Electric GEVO is a turbo charged diesel engine built and designed by General Electric, for the Evolution Series of locomotives. Originally designed to replace GE’s long standing 7FDL and to meet EPA Tier 2 emission standards, the engine was first produced for GE’s ES44AC in 2004. GE claims the engine is more efficient than its predecessor, accomplished by utilizing 12 cylinders as opposed to 16 to create the same amount of power. The engine has been used in GE-only locomotives, all branded as GE Evolution Series.
History
[edit]The GEVO prime mover was designed in 2003 to replace the 7FDL series. It was the first total redesign of an engine since the Universal Series. The first locomotives to use the GEVO were the ES44AC and ES40DC.
