Wärtsilä Vasa
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 series comprises three models, the Vasa 22, 32, and 46, with the number denoting the bore size of the engine.
Wärtsilä discontinued production of the series in 2010 to focus on newer technology. The Vasa series acted as a precursor to the newer 32 D and E series which have a higher power output.
