EMD 710

The EMD 710 is a line of diesel engines built by Electro-Motive Diesel (previously General Motors' Electro-Motive Division). The 710 series largely replaced the earlier EMD 645 series. The EMD 710 is a large two-stroke diesel engine that has a 710 cubic inch (11.63 liter) displacement per cylinder. Since its introduction, EMD has continually upgraded the 710G diesel engine. Power output has increased from 3,800 horsepower (2,800 kW) 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.

All EPA Tier 1 and EPA Tier 2 compliant models of the 710 are equipped with electronic fuel injection.
