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). It was originally intended to be used in the "European bomber" that eventually emerged as the Convair B-36. Only two ...
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 effort continued with a 5,000 shp (3,700 kW), weighing 1,700 kg (3,700 lb), completed by 1947. Evolution to the TV-12 12,000 shp (8,900 kW) engine required extensive use of new Soviet-developed alloys and was completed in 1951. The NK-12 is the most powerful turboprop engine to enter service, ahead of the Europrop TP400 (in 2005).
It's bigger than a Boeing 737's fuselage, and it's almost ready.
The long-awaited 777X, the world’s largest twin-engine jet, is expected to enter service in 2025, so this concept exists purely on paper for now. But Lufthansa, which will be among the first ...
The Acco Super Bulldozer is the largest and most powerful tracked bulldozer ever made. [citation needed] It was built in Portogruaro in northern Italy by the Umberto Acco company. The Acco super bulldozer was constructed mainly of Caterpillar parts; however, many other components were specially adapted. The dozer blade, for example, is bigger ...
One of the most powerful electric locomotives ever built, it also is the most powerful (short term) single-frame locomotive ever built (currently [when?] its maximum short term power is limited to 12,000 horsepower (8,948 kW)); It has immense short term power with a tractive effort of 312 kN up to a speed of 140 km/h (87 mph).
