EMD 265

EMD 265, or the H-Engine, (introduced in 1998^[1]) is a line of diesel engines built by Electro-Motive Diesel (EMD) for use in locomotives. Unlike EMD's previous 567, 645, and 710 lines of engines, which operate under a two-stroke cycle, the H-Engine operates as a four-stroke engine. Also distinguishing it from EMD's other engines is the notation used in its naming. In the 567, 645, and 710 engines the number refers to the displacement of each cylinder in cubic inches, while the H-Engine's "265" designation refers to the bore of the cylinder in millimeters.

Specifications

Although other variations of the H-Engine exist (including a 12 cylinder version), the following are the specifications for the GM16V265^[2]:

• 16 cylinders in a V configuration
• Up to 6,300 bhp (4,700 kW) at 1000 rpm
• 265 mm (10.4 in) bore
• 300 mm (11.8 in) stroke
• 1,010 cubic inches (16,600 cm³) displacement per cylinder^[1]
• Twin turbochargers

Usage in locomotives

Usage in locomotives includes the EMD SD89MAC, EMD SD90MAC^[1] and the EMD JT56ACe.
