Diagram of Priestman oil engine from The Steam engine and gas and oil engines (1900) by John Perry Petrol–electric Weitzer railmotor, first 1903, series 1906. The earliest recorded example of the use of an internal combustion engine in a railway locomotive is the prototype designed by William Dent Priestman, which was examined by William Thomson, 1st Baron Kelvin in 1888 who described it as ...
To establish the "largest" category, several factors take precedence: overall weight, which gives traction over driving axles; size (length and height of engine itself); and power, which may be in terms of raw horsepower, tractive effort, available power at axles (shaft horsepower) or, in the case of steam locomotives, available steam on a ...
GE worked with Deutz-MWM of Germany in 1994 to design and construct the 6,250-horsepower (4,660-kilowatt) 7HDL engine for the locomotives. [3] The first locomotive with a 7HDL was the "Green Machine" GE 6000, nicknamed for its green paint scheme.
The Big Boy has the longest engine body of any reciprocating steam locomotive, longer than two 40-foot buses. [12] They were also the heaviest reciprocating steam locomotives ever built; the combined weight of the 772,250 lb (350,290 kg) engine and 436,500 lb (198,000 kg) tender outweighed a Boeing 747. [12]
This engine, which succeeded Winton's 201A, was used in EMD's locomotives from 1938 until its replacement in 1966 by the EMD 645. It has a bore of 8 + 1 ⁄ 2 in (216 mm), a stroke of 10 in (254 mm) and a displacement of 567 cu in (9.29 L) per cylinder. Like the Winton 201A, the EMD 645 and the EMD 710, the EMD 567 is a two-stroke engine.
Locomotives exported to Indonesia are quite different from other locomotives produced by GE. They use the same type of engine across all models (GE 7FDL-8, except for UM 106T Locomotives which used Alco 12-244E). Despite using the same type of engine, the power capabilities from type to type are different as some models are equipped with dual ...
The EMD SD90MAC is a model of 6,000 hp (4,470 kW) [1] C-C diesel-electric locomotive produced by General Motors Electro-Motive Division (EMD). It is, with the SD80MAC, one of the largest single-engined locomotives produced by EMD and among the most powerful diesel-electric locomotives, surpassed only by the dual-engined DDA40X.
The word locomotive originates from the Latin loco 'from a place', ablative of locus 'place', and the Medieval Latin motivus 'causing motion', and is a shortened form of the term locomotive engine, [1] which was first used in 1814 [2] to distinguish between self-propelled and stationary steam engines.
