The Wärtsilä-Sulzer RTA96-C is the most powerful ship engine in the world.
Finnish Manufacturer Wartsila designed this two-stroke, turbocharged, low-speed diesel engine for the world’s largest container ships, which run on heavy fuel oil.
The engine’s biggest 14-cylinder version is 13.5 m tall, 26.5 m long and weighs more than 2300 tonnes, with the crankshaft alone weighing 300 tonnes and each piston weighing 5.5 tons.
It produces 80,08 MW or 107,390 horsepower, making it the world’s largest reciprocating engine.
This version entered commercial service in 2006 on board the Emma Maersk, once the largest container ship in the world when launched.
Its design was quite similar to the old RTA96C engine, but with common rail technology, in place of the conventional camshaft, chain gear, fuel pump and hydraulic actuator systems.
This gives maximum output at lower revolutions per minute, decreases fuel consumption and emits less harmful emissions compared to older mechanically controlled engines.
The engine generates a torque of up to 7,603,850
