Did you know
- The Wärtsilä W14 high-speed engine was officially launched in November 2018, a result of collaboration between Wärtsilä and Liebherr. It is derived from Liebherr's D96 engine family. The W14 continues a legacy of Wärtsilä's engine development, with the original Wärtsilä Vasa 14 being the company's first diesel engine, started in June 1959.
- The Wärtsilä W14 is positioned to complement Wärtsilä's portfolio in the high-speed engine segment, particularly in the power band around 1 MW, where Wärtsilä previously focused more on medium-speed engines like the Wärtsilä 20. It is designed to be the most compact marine engine in its power range.
- The W14 is chosen for its compact design, high power density, and compliance with stringent emission regulations (IMO Tier III and optional EU Stage V). Its optimal power-to-weight ratio and low fuel consumption across a wide load range make it suitable for applications with limited space and weight requirements, such as tugboats, fishing vessels, ferries, and auxiliary gensets.
