EMD 265

From Wikipedia, the free encyclopedia

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.
