Wärtsilä has announced that its 4‑stroke engine solution for ammonia fuel now offers a higher power rating. As part of the company’s ongoing development of ammonia‑fueled engine solutions, the upgrade to the Wärtsilä 25 Ammonia engine raises output to 315 kW per cylinder at 900 rpm and 345 kW per cylinder at 1000 rpm, matching the power level of the LNG‑fueled Wärtsilä 25DF engine. A key benefit of the upgrade is that fewer cylinders are required for a given power demand, which will reduce installation complexity and simplify maintenance.
