The new Wärtsilä 31 four-stroke engine is the most fuel-efficient four-stroke engine currently available on the market, according to the company. The diesel version of the engine consumes on average 8–10g/kWh less fuel than the nearest rival over the whole load range when compared to the gasoline version. This figure may be as low as 165g/kWh when operating at maximum efficiency.
Guinness World Records has certified the Wärtsilä 31 engine as the world’s most efficient 4-stroke diesel engine. It was released in 2015 and has since been certified as the world’s most efficient 4-stroke diesel engine. Furthermore, its efficient fuel consumption results in reduced levels of exhaust gas emissions as a result of its low fuel consumption.

How can we increase the efficiency of diesel engine?
- Run the engine on low fuel, which means that you’ll be using a lot of air. It is commonly known that operating on a low amount of gasoline increases efficiency.
- An increase in the compression ratio
- We require fresh cycles to be put into actual use.
- Make sure that the engine is operating at peak performance, which means low friction (slow engine speed) and low pumping work (air throttle more open).
