The EMD SD22ECO is a 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. Advertised benefits include: * EPA Tier-II compliance. * Fuel savings up to 25%. * Lube oil savings up to 50%. * Upgradeable software can be tuned for reduced emissions or improved fuel efficiency. * Microprocessor control offers diagnostics, wheel slip control, and optimal wheel/rail adhesion. * 184-day maintenance cycle instead of 92-day. * 15,000 MWh overhaul cycle. * Reduced maintenance expense due to use of standard 710 prime mover. * Automatic Engine Start Stop system keeps locomotive ready without wasting fuel. == References == * ''(SD22ECO advertisement by EMD )''.
