Wärtsilä is updating its Wärtsilä 31DF dual-fuel four-stroke engine to provide a greater power result within the very same measurements while reducing exhaust gas exhausts.
The Wärtsilä 31 engine was presented in 2015 and also acknowledged by Guinness World Records as the globe’s most reliable four-stroke diesel motor.
The gas adaptable DF variation can shedding gas and also givesmarine light gas oil, in addition to hefty gas oil and also has actually confirmed to a preferred for setup on a wide series of vessel kinds, consisting of cruise liner, ferryboats, vessels, and also angling vessels.
The power upgrade will certainly cause the present result series of 4.2 to 11 MW, being raised to a series of 4.6 to 12 MW with 600 kW/cylinder at 750 rpm, and also 580 kW/cylinder at 720 rpm.
“This power upgrade to the Wärtsilä 31DF represents significant added value to our customers,” claims Janne Klemola, General Manager, Product Management Small and also Medium birthed, WärtsiläMarine “Getting more power from an engine that already delivers exceptional efficiency, low emissions, and fuel flexibility is a real benefit. Regardless of whether the engine is installed on ships for propulsion or in land-based power plants for electricity generation, achieving this upgrade with fewer cylinders lowers the lifecycle costs, while at the same time reducing both the installation and maintenance costs.”
Since its intro, greater than 100 Wärtsilä 31 engines have actually been offered, and also over of 60,000 area running hrs have actually been collected.
“Sustainable power production is at the heart of Wärtsilä’s product development strategy, and with all sectors of the global economy looking for ways to combat climate change, optimizing efficiency and lowering emissions is of critical importance. Internal combustion engines will play a crucial role in balancing the future energy mix, and hence we are focusing strongly on continuously developing our engines to achieve better power generation performance, greater cost-efficiency, and to accept new fuels. Powering up the W31DF is one good example,” claims Jukka Lehtonen, Vice President, Technology & & Product Management, Wärtsilä Energy.
