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.
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.
Wärtsilä has only recently begun to offer V14 versions of its latest engine models, the 31, 46F, and 46DF. [3] In the past, V14 engines have also been offered by other manufacturers. Between 1982 and 1987 nineteen SA-15 arctic cargo ships were built with two 14-cylinder Wärtsilä-Sulzer 14ZV40/48 engines producing 7,700 kW (10,300 hp). [4]
The ship's power comes from six medium-speed, marine-diesel generating sets: three 16-cylinder Wärtsilä 16V46D common rail engines producing 18,480 kW (24,780 hp) each and three similar 12-cylinder Wärtsilä 12V46D engines producing 13,860 kW (18,590 hp) each. The fuel consumption of the main engines at full power is 5,213 litres (1,377 US ...
