The advantages of fuel flexibility in a small unit, also used for generating set applications

With the Wärtsilä 20DF, Wärtsilä is extending the benefits of dual-fuel (DF) technology to cover the entire power range. The engine offers ship owners and operators a compact unit that brings all the advantages of fuel flexibility to auxiliary applications, such as generating sets or as the prime mover in smaller vessels.

Based on the well proven and reliable Wärtsilä 20 diesel engine introduced in the early 1990s, fuel flexibility means the engine can be optimized for constant speed generating sets, as well as variable speed mechanical drives, for main engine applications.
