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 engines are thought to be the biggest ever built in the UK. [3] Engine No 6, also called The Sir William Prescott, has been restored to running order and is the largest fully operational triple-expansion steam engine in the world. [4] It may be seen in steam on various weekends throughout the year, and as a static display every Sunday ...
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. Reciprocating steam engines were progressively replaced in marine applications during the 20th century by steam ...

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]
One notable reciprocating engine from the World War II era was the 28-cylinder, 3,500 hp (2,600 kW) Pratt & Whitney R-4360 Wasp Major radial engine. It powered the last generation of large piston-engined planes before jet engines and turboprops took over from 1944 onward.
At 140 ft 2 + 1 ⁄ 2 in (42.74 m) overall, engine and tender, the S1 was the longest reciprocating steam locomotive ever; it also had the heaviest tender (451,840 lb / 205 tonnes), highest tractive effort (76,403 lbf (339.86 kN)) of a passenger steam engine when built and the largest driving wheels (7 feet in diameter) ever used on a ...
