Slightly too big for your pickup, aircraft or even a locomotive, this monster produces up to 108,920 brake horsepower (80,800 kW). It is 26.5 meters long and 13.5 m high and weighs in at 2,300 tonnes dry.
It is a two-stroke 14 cylinder in-line heavy fuel-oil engine. The engine has a capacity of 25,340 litres (L) or 1.55 million cubic inches.
At maximum speed (120 rpm) and lowest power it consumes about 6,200 L of fuel oil per hour, roughly 5,000 kg (5 tons) each hour, with a maximum of roughly three times this. At maximum economy the engine exceeds 50% thermal efficiency (Wartsila Sulzer RTA96-C) in terms of power delivered to the drive shank.
Over 300 have been built. A single RT-flex96C is used to power some of the world’s largest ships including the Emma Maersk, which was the world’s largest container ship when it entered service in 2006.
