The recently launched Wärtsilä 31 engine has achieved 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. This is far lower than any other 4-stroke diesel engine currently available on the market.
