The EMD SD22ECO is a 2,150 hp (1,600 kW) C-C diesel-electric locomotive rebuilt by Electro-Motive Diesel. It is, along with the GP22ECO, primarily the application of a conversion kit to an existing EMD SD40-type locomotive. This involves replacing the existing prime mover with an EPA Tier-II-compliant turbocharged V8 710G3A, with electronic fuel injection. The prime mover is mated to an AR10 alternator for traction power, a CA6 alternator for control power, and a computerized control system. This conversion does not alter the external appearance of the locomotive.
