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.
The Wärtsilä 20DF is a four-stroke dual-fuel engine that can be run on natural gas, marine diesel oil (MDO) or heavy fuel oil (HFO). The engine can switch over from gas to MDO/HFO and vice versa smoothly during engine operation without power interruption. The Wärtsilä 20DF design is based on the well proven and reliable Wärtsilä 20 diesel engine which was introduced on the market in the early 1990s. Wärtsilä 20DF completes the lower power range in the dual-fuel Wärtsilä engine family.
