The engine is the largest reciprocating engine in the world. The 14-cylinder version first entered commercial service in September 2006 aboard the Emma Mærsk . The design is similar to the older RTA96C engine, but with common rail technology (in place of traditional camshaft , chain gear , fuel pump and hydraulic actuator systems).
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 Marine (Finnish: Wärtsilä Meriteollisuus; Swedish: Wärtsilä Marinindustri) was a Finnish shipbuilding company. The company was created in 1987 in order to improve shipbuilding productivity by combining the Wärtsilä and Valmet yards under the same organisation.
The engines were designed for both shipboard and power plant applications. The engine could be ordered with a 220, 320, and 460 mm bore in both V and inline configurations. The inline style was available with up to 9 cylinders and V could support up to 18. The VASA32LN engine was redesigned with a longer stroke to increase horsepower.
Cummins and Wärtsilä Diesel agreed about setting up a joint venture to produce engines which would cover the gap in the engine ranges between both companies. The companies signed a letter of intent for the foundation of Cummins-Wärtsilä in December 1994. The ownership was shared 50% / 50% between Cummins and Wärtsilä Diesel.
The pre-war engines were Glow Head Engines in countless varieties. The first diesel engines were produced in 1938, when the company had 190 employees and an annual production of 160 engines. [2] The engines earned a reputation for being easy to operate and maintain. An engineer once stated that Wichmann were built for morons, but built by ...
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.
A marine LNG engine is a dual fuel engine that uses natural gas and bunker fuel to convert chemical energy in to mechanical energy. Due to natural gas' cleaner burning properties, the use of natural gas in merchant ship propulsion plants is becoming an option for companies in order to comply with IMO and MARPOL environmental regulations.
