Wärtsilä

Wärtsilä is the Finnish engineering group whose engines power ships and power plants across the world, and it is recorded here as the make behind those engines. The company dates its beginning to 12 April 1834, when a sawmill was approved by a rapids in Tohmajärvi in Karelia, and the business grew through iron works and shipyards before it turned to diesel engines. It signed a licence agreement with Krupp Germania Werft in 1938, built its first diesel engine in Turku in November 1942 and began designing its own engines in Vaasa, where the first Wärtsilä designed diesel, the Vasa 14, first ran in June 1959. Later acquisitions of Nohab, SACM, Stork-Werkspoor and New Sulzer Diesel widened the range of medium-speed and low-speed engines sold under the name, and in 2015 the two-stroke portfolio moved into the WinGD joint venture.
