Did you know
- The Wärtsilä 46F is a four-stroke medium-speed engine series that was initially introduced for marine applications in 2004, with a six-cylinder engine beginning test bed operations in Vaasa. It is the latest iteration in a successful marine engine series that began with the Vasa 46, launched in 1987.
- The Wärtsilä 46F is positioned as a high-power diesel engine within Wärtsilä's portfolio, suitable for larger vessels and installations, offering a power range between 7.5 MW and 20 MW. It sits above engines like the Wärtsilä 32, which is a robust engine for propulsion and onboard power, and the Wärtsilä 20, a compact engine for auxiliary and propulsion applications. The Wärtsilä 46DF, a dual-fuel variant, is based on the Wärtsilä 46F and Wärtsilä 50DF engine families, extending the dual-fuel range.
- The Wärtsilä 46F is chosen for its exceptional fuel flexibility, allowing it to run on various fuels including heavy fuel oil (HFO), marine diesel oil (MDO), liquid biofuels, and with methanol-ready and methanol versions available. This adaptability enables it to meet changing regulatory requirements and offers operators the flexibility to select fuels based on price, availability, and emission regulations.
