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.
The EMD 645 is a family of two-stroke diesel engines that was designed and manufactured by the Electro-Motive Division of General Motors.While the 645 series was intended primarily for locomotive, marine and stationary engine use, one 16-cylinder version powered the 33-19 "Titan" prototype haul truck designed by GM's Terex division
Lobe pump. A lobe pump, or rotary lobe pump, is a type of positive displacement pump. It is similar to a gear pump except the lobes are designed to almost meet, rather than touch and turn each other. An early example of a lobe pump is the Roots Blower, patented in 1860 [1] to blow combustion air to melt iron in blast furnaces, but now more ...
But, unlike the earlier 645 and 567, which could use either turbochargers or Roots blowers, the turbocharger is a standard feature of most 710 models. Horsepower for any naturally aspirated engine is usually derated at 2.5% per 1,000 feet (300 m) above mean sea level, a penalty which becomes extremely large at altitudes of 10,000 feet (3,000 m ...
This was an opposed-piston engine with a choice of two, three and four cylinders (2ZG9, 3ZG9, 4ZG9); the two-cylinder version developed 120 bhp. Its layout was very similar to the Commer engines, but it used a piston scavenge pump rather than a Roots blower. This was mounted vertically above one rocker, driven by a bellcrank from the main rockers.
Contents. EMD SD24. The EMD SD24 is a 2,400 hp (1,800 kW) six-axle (C-C) diesel-electric locomotive built by General Motors ' Electro-Motive Division of La Grange, Illinois between July 1958 and March 1963. [ 1 ] A total of 224 units were built for customers in the United States, comprising 179 regular, cab-equipped locomotives and 45 cabless B ...
A compressor is a mechanical device that increases the pressure of a gas by reducing its volume. An air compressor is a specific type of gas compressor. Many compressors can be staged, that is, the gas is compressed several times in steps or stages, to increase discharge pressure.
The 6–71 blower, for example, is designed to scavenge six cylinders of 71 cu in (1.2 L) each, resulting in an engine with a total displacement of 426 cu in (7.0 L)). However, because 6–71 is the engine's designation rather than that of the blower, the actual displacement of the blower is less; for example, a 6–71 blower pumps 339 cu in (5 ...
