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 Vasa is an engine series built by Finnish diesel engine manufacturer Wärtsilä. It was released in 1977 and remained in production until 2010. These medium speed diesels were produced in and named after Vasa, Finland. The lead designer of the first engine was Wilmer Wahlstedt.
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.
Cummins-Wärtsilä Engine Co. was an Anglo-French joint venture which existed between 1995 and 2000. Jointly owned by Cummins and Wärtsilä NSD , it was a manufacturer of operated diesel engines. [ 1 ]
A V14 engine is a V engine with 14 cylinders mounted on the crankcase in two banks of seven cylinders. It is a very rare layout, used almost exclusively on large medium-speed diesel engines used for power generation and marine propulsion .
The twelve-cylinder engine was used in the British Rail Class 47, Romanian Railways Class 60/62, Polish Railways Class ST43, China Railways ND2, and several others. The 12LDA28 engine was a double bank engine having, in effect, two six-cylinder engines side by side, rather than a V-type as favoured by many other manufacturers. Sulzer V-type ...
