Wärtsilä 34DF

Advanced dual-fuel technology & efficiency, also used for generating set applications

The Wärtsilä 34DF is manufactured in configurations of from 6L up to 16V giving 500 kW per cylinder and a total maximum mechanical output of 8000 kW. The engine speed is 750 rpm. 

Fuel flexibility

The Wärtsilä dual-fuel engine capability enables ships to be operated on either conventional liquid marine fuels or LNG. The switch between fuels can be made seamlessly without loss of power or speed. Such fuel flexibility enables compliance with emission regulations in controlled areas, while giving operators the option of determining the fuel according to cost and availability.

When operating in gas mode, the Wärtsilä 34DF engine is already compliant with IMO Tier III regulations without any secondary exhaust gas purification systems. Also when fuelled by gas, the SOx and CO2 emissions are notably reduced, and smokeless operation is attained.

In liquid fuel oil mode, the Wärtsilä dual-fuel engines are fully compliant with the IMO Tier II exhaust emissions regulations set out in Annex VI of the MARPOL 73/78 convention. The engine is able to operate efficiently and economically on low sulphur fuels (<0.1% S), making it suitable for operation in emission-controlled areas.

United States Environmental Protection Agency The newly obtained certification of emission standard compliance from the United States Environmental Protection Agency (EPA) for the Wärtsilä 34DF further endorses the environmental compliance of this engine.
