The EMD 265H had a bore of 265 millimetres (10.4 in) and stroke of 300 millimetres (12 in) (so that the displacement per cylinder was 1010 cubic inches) with the 16 cylinder GM16V265H rated at 4,700 kilowatts (6,300 hp) at 1000 rpm, with a brake mean effective pressure of 21.3 bars (2,130 kPa).
The "S" designation originally stood for six hundred horsepower and the "N" designation for nine hundred horsepower, although they were used for the more general designation of smaller and larger engine models after the more powerful 567 model engines replaced the Winton engines. The "C" designation stood for cast frame locomotives and the "W ...
The 567 engine was continuously improved and upgraded. The original six-cylinder 567 produced 600 hp (450 kW), the V-12 1,000 hp (750 kW), and the V-16 1,350 hp (1,010 kW). EMD began turbocharging the 567 around 1958; the final version, the 567D3A (built from October, 1963, to about January, 1966) produced 2,500 hp (1,900 kW) in its V-16 form.
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 ...
The EMD F-units followed the basic B-B truck design of the TA model, but with a V-16 EMD 567 prime mover generating 1350 hp as introduced in 1939. E-units standardized the two engine configuration for passenger locomotives to maximize power and, while the less-reliable Winton Diesel prime movers were in use, faced a less severe loss of power ...
The Prima Diesel-electric locomotives are a class of medium and heavy, four- and six-axle, passenger and freight mainline locomotives. [1] They have been built both to 1,435 mm (4 ft 8 + 1 ⁄ 2 in) standard and 1,668 mm (5 ft 5 + 21 ⁄ 32 in) broad gauges, and find use in the Middle East, Europe and North America.
That effort produced the first practical two-stroke diesel engines in the 400 to 1,200 hp (300 to 900 kW) range. The 2-stroke Winton Model 201A engines featured uniflow scavenging with intake ports in the cylinder walls and exhaust valves in the cylinder heads, and mechanical injection , which would carry over to later Cleveland Diesel designs.
The EMD 710 is a line of diesel engines built by Electro-Motive Diesel (previously General Motors' Electro-Motive Division). The 710 series replaced the earlier EMD 645 series when the 645F series proved to be unreliable in the early 1980s 50-series locomotives which featured a maximum engine speed of 950 rpm.
