Finland’s Wärtsilä has reported that its recently launched Wärtsilä 31 engine has won a Guinness World Records title for the most efficient 4-stroke diesel engine.
The listing is based on the Wärtsilä 31 engine’s highest fuel efficiency levels, with its diesel fuel consumption being as low as 165 g/kWh.
The Wärtsilä 31 engine is designed to serve various types of vessels in the offshore, cruise & ferry, and other marine segments where the power range requirement is from 4.2 to 9.8 MW.
The engine can be operated using a range of different fuels, and comes in three alternative versions; Diesel, Dual-Fuel (DF) and Spark-Ignited Gas (SG).
”The marine industry is focusing more than ever on efficiency and flexibility. The validation of the Wärtsilä 31 by Guinness World Records as being the most efficient 4-stroke diesel engine in the world speaks for itself. Ship owners and operators now have the chance to take a more efficient approach to improving vessel operations and reducing costs. The Wärtsilä 31 clearly redefines efficiency,” said Roger Holm, Senior Vice President, Engines, Wärtsilä Ship Power.
