Wärtsilä’s extremely environment friendly Wärtsilä 31 four-stroke diesel engine is being upgraded to ship a better energy output throughout the similar bodily footprint. The improve will outcome within the present output vary of 4.9 to 9.8 MW, being elevated to a spread of 5.2 to 10.4 MW. The energy improve provides clients the choice to pick out fewer cylinders, thereby lowering the required engine room house, in addition to lessening upkeep necessities.
The new output of 650 kW per cylinder is now the best for engines of this bore measurement, says Wärtsilä.
The Wärtsilä 31 was initially launched in 2015 and was acknowledged by Guinness World Records as being the world’s most efficient four-stroke diesel engine. In addition to its excessive effectivity, the engine’s financial gasoline consumption in flip leads to decrease ranges of exhaust fuel emissions.
“With this power upgrade we are delivering significant added value to our customers,” says Lars Anderson, director of product administration at Wärtsilä. “The Wärtsilä 31 is already the best engine in its class, and this development widens its market advantage even further. By extending its performance, we are making a real contribution to greater sustainability and supporting our commitment to a decarbonized future.”
The first deliveries of the upgraded engine are going down throughout the first half of 2023. Already, seven larger energy output Wärtsilä 31 engines have been contracted.
Ronald Ervik, Managing Director of Herøyhav, a Norwegian fishing firm and one of many first recipients of the upgraded engine mentioned: “For our new vessel we opted for the Wärtsilä 31 engine because it is the most modern and most efficient medium-speed marine diesel engine on the market. Not only will it give us the power we need and with dimensions that fit our engine room design, but it will also lower fuel consumption.”
The Wärtsilä 31 has confirmed to be fashionable for set up on a broad vary of vessel sorts, together with amongst others, fishing vessels, ice breakers, ferries, cruise vessels, cable layers, and catamarans.
