EMD 645

The EMD 645 family of diesel engines was designed and manufactured by the Electro-Motive Division of General Motors. Intended primarily for locomotive, marine and stationary engine use, one 16-cylinder version powered the 33-19 "Titan" prototype haul truck designed by GM's Terex...

Cylinder (engine)

A cylinder is the central working part of a reciprocating engine or pump, the space in which a piston travels. Multiple cylinders are commonly arranged side by side in a bank, or engine block, which is typically cast from aluminum or cast iron before receiving precision machine work...

. Since its introduction, EMD has continually upgraded the 710G diesel engine. Power output has increased from 3800 hp on 1984's 16-710G3A to 4300 horsepower (as of 2006) on the 16-710G3C-T2.

Over the production span of certain locomotive models upgraded engine models have been fitted when they became available. For example an early 1994-built SD70MAC had 16-710G3B, where an SD70MAC built in 2003 would have a 16-710G3C-T1.
