The Wärtsilä RT-flex96C is a two-stroke turbocharged low-speed diesel engine designed by the Finnish manufacturer Wärtsilä. It is designed for large container ships that run on heavy fuel oil . Its largest 14-cylinder version is 13.5 meters high, 26.59 meters long, weighs over 2,300 tonnes , and produces 80.08 megawatts .
This is the power rating table generated for the Vasa 32LN engine. Engine power ratings are determined by how the engine is being used. The Vasa engines offer 375 kW/cyl and 410 kW/cyl. As the number of cylinders increase, the power increases. The size of the engine depends on the application it is being used for. [1]
The only straight-14 engine known to reach production is part of the Wärtsilä-Sulzer RTA96-C family of 6-cylinder to 14-cylinder two-stroke marine engines. This engine is used in the Emma Mærsk , which was the world's largest container ship when it was built in 2006.
Sulzer's marine engine range in 1969 extended from the 3 cylinder version of the A25 auxiliary engine at 550 bhp to the 12 cylinder 48,000 bhp 12RND105 engine, 10 metres high, with cylinders over a metre in diameter. [14] More recently these main engines have been replaced by the RTA series of engines, still two stroke.
The engine models are identified by the cylinder bore diameter in centimeters, which as of 2024 range from 20 to 46 centimetres (7.9 to 18.1 inches). The smallest engine series, Wärtsilä 20, produces a modest 200 to 220 kW (270 to 300 hp) per cylinder and is available in inline configurations from 4 to 9 cylinders.

The ship's power comes from six medium-speed, marine-diesel generating sets: three 16-cylinder Wärtsilä 16V46D common rail engines producing 18,860 kilowatts (25,290 hp) each and three similar 12-cylinder Wärtsilä 12V46D engines producing 13,860 kilowatts (18,590 hp) each. The fuel consumption of the main engines at full power is 1,377 US ...
These hovercraft, manufactured by Wärtsilä, were powered by a 625 kW stern-mounted diesel engine driving two fans giving the platform a hovering height of 0.6–0.7 m (2.0–2.3 ft). They were capable of carrying a payload of 38 tonnes over ice, water, land and marshy terrain when towed by a tractor or a tug or, if necessary, by using an ...
