The engine is the largest reciprocating engine in the world. The 14-cylinder version first entered commercial service in September 2006 aboard the Emma Mærsk. The design is similar to the older RTA96C engine, but with common rail technology (in place of traditional camshaft, chain gear, fuel pump and hydraulic actuator systems).
The Lycoming XR-7755 was the largest piston aircraft engine ever built in the United States, [Note 1] with 36 cylinders totaling about 7,750 in 3 (127 L) of displacement and a power output of 5,000 horsepower (3,700 kilowatts).
The largest reciprocating engine in production at present, but not the largest ever built, is the Wärtsilä-Sulzer RTA96-C turbocharged two-stroke diesel engine of 2006 built by Wärtsilä. It is used to power the largest modern container ships such as the Emma Mærsk.
A marine steam engine is a steam engine that is used to power a ship or boat. This article deals mainly with marine steam engines of the reciprocating type, which were in use from the inception of the steamboat in the early 19th century to their last years of large-scale manufacture during World War II.
Lycoming Engines is a major American manufacturer of aircraft engines. With a factory in Williamsport, Pennsylvania , Lycoming produces a line of horizontally opposed , air-cooled, four, six and eight-cylinder engines including the only FAA -certified aerobatic and helicopter piston engines on the market.
The largest reciprocating IC are low speed CI engines of this type; they are used for marine propulsion (see marine diesel engine) or electric power generation and achieve the highest thermal efficiencies among internal combustion engines of any kind.
The Chapin Mine Steam Pump Engine, also known as the Cornish Pump, is a steam-driven pump located at the corner of Kent Street and Kimberly Avenue in Iron Mountain, Michigan, United States. It is the largest reciprocating steam-driven engine ever built in the United States. [3]
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]
