Wärtsilä Expands Dual Fuel Technology

Posted on December 1, 2009

Wärtsilä has extended its dual-fuel technology to the lower power range with the launch of the new Wärtsilä 20DF engine. It 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.

The new Wärtsilä 20DF engine is an example of the ability to utilize gas as a main fuel for marine operations. Natural gas is a practical and attractive option at a time when prices for liquid fuels are uncertain, and when environmental requirements are becoming increasingly stringent.

With the launch of the Wärtsilä 20DF, Wärtsilä is extending the benefits of dual-fuel (DF) technology to cover its power range. Based on the 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.

Installed alongside Wärtsilä 34DF or 50DF main propulsion machinery, a Wärtsilä 20DF generating set completes the multi-fuel engine room concept. Compact and light, the Wärtsilä 20DF is intended for use in those vessel types where the Wärtsilä 20 is currently installed.
