V20 Engine
A V20 engine is a twenty-cylinder piston engine where two banks of ten cylinders are arranged in a V configuration around a common crankshaft. Large diesel V20 engines have been used in diesel locomotives, haul trucks, electric generators and marine applications. History Beginning in the late-1930s, Mercedes-Benz produced several large V20 diesel engines for use in marine applications. The first engine was the ''MB 501'' which was based on the ''MB 500'' V12 engine and was installed in the 1937 class Schnellboot (fast attack boat) and several submarines. Later versions included the supercharged ''MB 511'' engine and the ''MB 518'', which also added an intercooler. A copy of the MB 511 was produced by VEB Motorenwerk in Ludwigsfelde and called the ''VEB 20 KVD 25''. Production of the MB 518 resumed in 1951, and a version of the engine was also manufactured by MTU, called the ''MB 20 V 672''. The Electro-Motive Diesel EMD 645E3 two-stroke V20 turbo-diesel engine was used in 1 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Internal Combustion Engine
An internal combustion engine (ICE or IC engine) is a heat engine in which the combustion of a fuel occurs with an oxidizer (usually air) in a combustion chamber that is an integral part of the working fluid flow circuit. In an internal combustion engine, the expansion of the high-temperature and high-pressure gases produced by combustion applies direct force to some component of the engine. The force is typically applied to pistons (reciprocating engine, piston engine), turbine blades (gas turbine), a Wankel engine, rotor (Wankel engine), or a propulsive nozzle, nozzle (jet engine). This force moves the component over a distance. This process transforms chemical energy into kinetic energy which is used to propel, move or power whatever the engine is attached to. The first commercially successful internal combustion engines were invented in the mid-19th century. The first modern internal combustion engine, the Otto engine, was designed in 1876 by the German engineer Nicolaus ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EMD SD45-2
The EMD SD45-2 is a 6-axle diesel-electric locomotive built by General Motors Electro-Motive Division (EMD). EMD built 136 locomotives between 1972 and 1974, primarily for the Atchison, Topeka and Santa Fe Railway (ATSF). The SD45-2 was an improved version of the EMD SD45; the primary visual difference is the absence of flared radiators on the SD45-2. Design Part of the EMD Dash 2 line, the SD45-2 was an upgraded SD45. Like the SD45, the SD45-2 had an EMD 645E3 20-cylinder engine producing . The main spotting difference between an SD45 and an SD45-2 was the long hood and the rear radiator. On the SD45 the long hood is flared whereas on the SD45-2 it is vertical and the rear cooling fans are more spread out on the top of the rear of the long hood. This unit used the same frame as the EMD SD40-2 and EMD SD38-2. The largest owner of the SD45-2 was the Atchison, Topeka, & Santa Fe with 90 units, the Clinchfield had 18 units, Seaboard Coast Line had 15 units and Erie Lackawann ...

Locomotive Engines
A locomotive is a rail vehicle that provides the motive power for a train. Traditionally, locomotives pulled trains from the front. However, push–pull operation has become common, and in the pursuit for longer and heavier freight trains, companies are increasingly using distributed power: single or multiple locomotives placed at the front and rear and at intermediate points throughout the train under the control of the leading locomotive. Etymology The word ''locomotive'' originates from the Latin 'from a place', ablative of 'place', and the Medieval Latin 'causing motion', and is a shortened form of the term ''locomotive engine'', which was first used in 1814 to distinguish between self-propelled and stationary steam engines. Classifications Prior to locomotives, the motive force for railways had been generated by various lower-technology methods such as human power, horse power, gravity or stationary engines that drove cable systems. Few such systems are still ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
V Engines
A V engine, sometimes called a Vee engine, is a common configuration for internal combustion engines. It consists of two cylinder banks—usually with the same number of cylinders in each bank—connected to a common crankshaft. These cylinder banks are arranged at an angle to each other, so that the banks form a "V" shape when viewed from the front of the engine. V engines typically have a shorter length than equivalent inline engines, however the trade-off is a larger width. V6, V8 and V12 engines are the most common layout for automobile engines with 6, 8 or 12 cylinders respectively. History The first V engine, a two-cylinder V-twin, was designed by Wilhelm Maybach and used in the 1889 Daimler Stahlradwagen automobile. The first V8 engine was produced in 1903, in the form of the Antoinette engine designed by Léon Levavasseur for racing boats and airplanes. The first V12 engine was produced the following year by Putney Motor Works in London, again for use in racing b ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Detroit Diesel Series 149
The Detroit Diesel 149 is a series of two-stroke diesel engines manufactured by Detroit Diesel which were first announced in early 1966. After Detroit Diesel was spun off in 1988 and later acquired by MTU, production of Series 149 engines was discontinued around 2000. Development The first configuration was announced at the 50th anniversary SAE Tractor meeting. It was a naturally aspirated 12V149 rated at about soon followed by a naturally aspirated 16V149 rated at about . As manufacturers in the marine, construction, mining, and many other industries required more power output, Detroit added turbocharging and intercooling to the engine. As originally designed, the ''Oliver Hazard Perry''-class frigates were equipped with 16V-149TI diesels for electrical generation, but these were replaced starting in 2000 after the Series 149 went out of production. In 1992, Republic Locomotive announced a new line of locomotives powered by Series 149 engines intended for switching and commute ...

EMD SD80MAC
The EMD SD80MAC was a C-C diesel-electric locomotive. It was powered by a 20-cylinder version of EMD's 710G prime mover, and was the second diesel locomotive by GM-EMD to use a V20 engine, since EMD's SD45 series. It introduced a wide radiator housing similar to GE Transportation locomotives and the placement of dynamic brakes at the rear of the locomotive, which is a quieter location, features that were incorporated into the SD90MAC and SD70ACe models. Key spotting differences between the SD80MAC and SD90MAC include no external rear sandbox on the SD90MAC, no rear lighted number boards on the SD90MAC, and the placement of the front numberboards (above the cab windows on the SD80MAC, on the nose on most SD90MACs). The SD80MAC also had recessed red marker lights in the nose, an identifying feature unique to Conrail (CR) locomotives, although Norfolk Southern (NS) had removed the lights on most of their former Conrail engines. All 30 SD80MAC units built were delivered to Conr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
EMD 710
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.40-series versions of the 645, save the initial teething problems with the 20-645E, which were eventually resolved, proved to be exceptionally reliable. The EMD 710 is a relatively large medium-speed two-stroke diesel engine that has displacement per cylinder, and a maximum engine speed of 900 rpm.Same parts suitable for 1000 rpm speed, yet rated lower because of earlier problems in EMD 645. Factory-fitted governor limits to 900 rpm. In 1951, E. W. Kettering (son of Charles F. Kettering) wrote a paper for the ASME entitled, ''History and Development of the 567 Series General Motors Locomotive Engine'', which goes into great detail about the technical obstacles that were e ...

EMD SD45T-2
The SD45T-2 is a model of diesel-electric locomotive built by EMD for the Southern Pacific Railroad. Like the later SD40T-2 it is colloquially nicknamed a tunnel motor. 247 total units (including the original EMD/SP joint-venture prototype) were produced from February 1972 to June 1975, including 84 for SP's subsidiary Cotton Belt. From April 1986 to December 1989, 126 were rebuilt and re-designated as ''SD45T-2R'', including 24 for Cotton Belt. The SD45T-2 is a variant of the venerable SD45 that featured the "Dash 2" upgrade components such as improved electronics and high traction trucks, with the "T" denoting its cooling system modifications. The intake for radiator cooling air was moved to the walkway level and the cooling fans themselves were under the radiator cores, instead of above. Tunnel motors were built for mountainous areas in the western United States, where SP had previously encountered repeated overheating issues on their SD45s. The later SD40T-2 looks similar ...

EMD SD45
The SD45 is a six-axle diesel-electric locomotive class built by General Motors Electro-Motive Division between 1965 and 1971. It has an EMD 645E3 twenty- cylinder engine generating on the same frame as the SD38, SD39, SD40, and SDP40. As of 2023, most SD45s have been retired, scrapped or rebuilt to SD40-2 standards. Design A total of 1,260 were built for American railroads before the SD45-2 replaced it in 1972, along with the related SD45T-2 'Tunnel Motor'. SD45s had several teething problems. Reliability was not as high as anticipated; the twenty-cylinder prime mover was prone to crankshaft failure from engine block flex. Though it produced more than the 16-645E3 in the SD40, some railroads felt the extra horsepower was not worth it, even after EMD strengthened the block to eliminate crankshaft failures. At low speeds when tractive effort was adhesion-limited, the SD45 provided no advantage over the SD40. Buyers included the Burlington Northern, Southern Pacific ...
