Posted on June 5, 2013

Wärtsilä has further developed its dual fuel technology and introduced a more powerful version of its Wärtsilä 34DF engine.

The new and upgraded version of the Wärtsilä 34DF engine increases the efficiency in both liquid and gas operating modes and offers a power increase up to 500kw per cylinder.

This increased output means that the Wärtsilä 34DF now covers a power range from 2.9 MW to 8 MW. In addition to the increase in power, fuel economy is also enhanced, especially when operating in liquid fuel mode, the company said.

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. 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, Wärtsilä said.
