The EMD 645 is a family of diesel engines built by General Motors Electro-Motive Division for locomotive, marine and stationary engine use. A diesel engine is an Internal combustion engine which operates using the Diesel cycle (named after Dr Electro-Motive Diesel Inc (formerly the Electro-Motive Division of General Motors Corporation is currently the world's second largest builder of Railroad A locomotive is a railway Vehicle that provides the motive power for a Train. An ocean (from Greek, ''Okeanos'' (Oceanus) is a major body of saline water, and a principal component of the Hydrosphere. A stationary engine is an engine whose framework does not move Chronologically the 645 series falls between the earlier 567 series and the later 710 series, but it is still supported by EMD. The EMD 567 is a line of Diesel engines built by General Motors' Electro-Motive Division. The EMD 710 is a line of Diesel engines built by Electro-Motive Diesel (previously General Motors ' Electro-Motive Division

History
The 645 series engine introduced in 1965 was a development of the earlier 567 engine. It had a larger bore, 91⁄16 inches instead of 8½ inches but maintained the same stroke. A stroke is a single action of certain Engines In a steam, Otto or Diesel Piston Engine, a stroke is the action of Engine speed was also increased, from 800/835 to 900 rpm. It was first used in EMD's "40 series" (GP40, SD40) in 3000 hp 16 cylinder form, and in 20 cylinder, 3600 hp form in the SD45. An EMD GP40 is a 4-axle diesel Locomotive built by General Motors Electro-Motive Division between November 1965 and December 1971. An EMD SD40 is a 6-axle diesel Locomotive built by General Motors Electro-Motive Division between January 1966 and August 1972 The EMD SD-45 is a six-axle diesel Locomotive built by General Motors Electro-Motive Division between December 1965 and December 1971
Specification
All 645 engines are 2-stroke 45° V-engines. The two-stroke Internal combustion engine differs from the more common Four-stroke engine by completing the same four processes (intake compression combustion exhaust A V engine is a common configuration for an Internal combustion engine. Each cylinder is of 645 in³ (10. A cylinder is the central working part of a Reciprocating engine, the space in which a Piston travels 57 l) displacement, hence the name; with a bore of 91⁄16 inches (230. Engine displacement is defined as the total Volume of air/fuel mixture an Engine can draw in during one complete engine cycle it is normally stated in Cubic 2-mm), a stroke of 10 inches (254-mm) and a compression ratio of 14. The compression ratio is a single number that can be used to predict the performance of any engine particularly piston engines (but can be used on essentially any Internal-combustion 5:1. The engines are fitted with either a single or twin Roots blower, or a mechanically assisted Turbocharger depending on required power output
