Wärtsilä adds NextDF tech to its 25DF engine

Wärtsilä has introduced its NextDF feature for the Wärtsilä 25DF dual-fuel engine.

Additionally, the nitrogen oxide (NOx) emissions are lower than on the standard Wärtsilä 25DF engine which already has emission levels below IMO Tier III.

In 2023, Wärtsilä first introduced the new technology for its Wärtsilä 31DF engine. Thanks to...
