V20 engine

Last updated

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.

Mercedes-Benz MB 511 marine diesel engine

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. [1] [2] 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, [1] and a version of the engine was also manufactured by MTU, called the MB 20 V 672.[ citation needed ]

The Electro-Motive Diesel EMD 645E3 two-stroke V20 turbo-diesel engine was used in 1960s diesel-electric locomotives such as the EMD SD45. The engine has a displacement of 211 L (12,876 cu in) and produces a net traction of 2.7 MW (3,600 hp). [3] [4] [5] The maximum gross power output is closer to 5,000 hp when operated in self-test mode (with the generated output being dissipated by resistors). Later versions of the EMD 645 engine were used in the EMD SD45-2 and EMD SD45T-2 locomotives. EMD also produces a V20 version of the EMD 710 diesel engine, which was used in the 1995 EMD SD80MAC locomotive. [6] [7] The EMD 710 remains in production to this day,[ citation needed ] and is mostly used in power generation and marine propulsion.

The Detroit Diesel Series 149 20V149 has an output of 2,936 hp (2,189 kW) from a capacity of 2,980 cu in (48.8 L). It was discontinued in 2000.

Current production V20 diesel engines include the Fairbanks Morse FM | MAN 28/33D STC, FM | MAN 32/44CR, FM | MAN 175D, FM | COLT-PIELSTICK PA6B STC. Others are the Wärtsilä 20V32 which produces up to 9.8 MW (13,100 hp), [8] the MTU 20V1163 6 MW (8,045 hp)MTU 20V4000 2.8 MW (3,755 hp), MTU 20V8000 10 MW (13,410 hp), Cummins 120.0L QSK120 (5,000 hp). Caterpillar C175-20 4 MW (5,364 hp) and the G3520 series.

A V16 engine is a sixteen-cylinder piston engine where two banks of eight cylinders are arranged in a V configuration around a common crankshaft. V16 engines are less common than engines with fewer cylinders, such as V8 and V12 engines. Each bank of a V16 engine can be thought of as a straight-eight, a design that can be inherently balanced. Most V16 engines have a 45° bank angle.

The SD80MAC was a 5,000 horsepower (3.7 MW) 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. 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.

The EMC E3 is a 2,000 horsepower (1,500 kW), A1A-A1A passenger train locomotive that was manufactured by Electro-Motive Corporation of La Grange, Illinois. The EMC demonstrator #822 was released from La Grange for test on September 12, 1938. The cab version, or E3A, was manufactured from September 1938 to June 1940, and 17 were produced. The booster version, or E3B, was manufactured in March 1939 and September 1939, and 2 were produced. The 2,000 hp (1,500 kW) was achieved by putting two 1,000 horsepower (750 kW), 12-cylinder, model 567 engines in the engine compartment. Each engine drove its own electrical generator to power the traction motors. The E3 was the fourth model in a long line of passenger diesels of similar design known as EMD E-units.

EMD E-units were a line of passenger train streamliner diesel locomotives built by the General Motors Electro-Motive Division (EMD) and its predecessor the Electro-Motive Corporation (EMC). Final assembly for all E-units was in La Grange, Illinois. Production ran from May 1937, to December, 1963. The name E-units refers to the model numbers given to each successive type, which all began with E. The E originally stood for eighteen hundred horsepower, the power of the earliest model, but the letter was kept for later models of higher power.

<span class="mw-page-title-main">EMD F-unit</span> Line of diesel-electric locomotives

EMD F-units are a line of diesel-electric locomotives produced between November 1939 and November 1960 by General Motors Electro-Motive Division and General Motors-Diesel Division. Final assembly for all F-units was at the GM-EMD plant at La Grange, Illinois, and the GMDD plant in London, Ontario. They were sold to railroads throughout the United States, Canada and Mexico, and a few were exported to Saudi Arabia. The term F-unit refers to the model numbers given to each successive type, all of which began with the letter F. The F originally meant "fourteen", as in 1,400 horsepower (1,000 kW), not "freight". Longer EMD E-units for passenger service had twin 900-horsepower (670 kW) diesel engines. The E meant "eighteen" as in 1,800 horsepower (1,300 kW). Similarly, for early model EMD switchers, S meant "six hundred" and N meant "nine hundred horsepower".

<span class="mw-page-title-main">Indian locomotive class WDG-5</span> Indian railways locomotive class

The Indian locomotive class WDG-5 is a class of heavy haul Diesel-electric locomotive built by Banaras Locomotive Works, Varanasi in collaboration with Electro-Motive Diesel. At a rated power output of 5,500 horsepower (4,100 kW), it is the second most powerful diesel locomotive class on Indian Railways, just out-powered by the 6,000 horsepower (4,500 kW) WDG-6G. Derived from the EMD SD80MAC, it was meant as a direct upgrade to the WDG-4 aka GT46MAC. The locomotive series is named Bheem, after the strong Pandav brother from epic Mahabharata. The loco has the 2-stroke Turbocharged EMD 20N-710G3B-ES of the EMD SD80MAC and an AC-AC transmission. Since the loco has been developed by installing a v20-710 prime mover and replacing the standard v16 in the WDG4 GT46MAC locomotive, the model was re-designated by adding 4 to the predecessor model, with GT-46 becoming GT-50, owing to the number of cylinders going from 16 to 20, thereby making it the First EMD locomotive in the GT-series to use a v20-710 engine.
