The Wärtsilä RT-flex96C is a turbocharged, two-stroke reciprocating diesel engine designed to power large container ships and is the world’s largest engine. Built in the Aioi Works of Japan's Diesel United, Ltd, it has a length of 27 metres (88 ft 7 in), is 13.5 metres (44 ft 4 in) high and weighs over 2,300 tonnes. Using improved fuel injection methods, which have done away with traditional camshaft, chain gear, fuel pumps and hydraulic actuators, the power output of the 14 cylinder version has, in 2008, attained 84.42 Megawatts (114,800 bhp [brake horsepower]). Thus it has achieved better performance with lower fuel consumption and lower harmful emissions. The engine powers the MV Emma Maersk, the world’s largest container ship.
