The Wärtsilä 31 engine

Wärtsilä has recently launched its Wärtsilä 31 medium speed engine – which has achieved a Guinness World Records title for the most efficient 4-stroke diesel engine.

The new engine is designed to serve a variety of vessel types requiring main engine propulsion in the 4.2 to 9.8 MW power range – making it ideal for large fishing vessels. 

According to the company, the Wärtsilä 31 has significantly reduced maintenance requirements, while raising fuel efficiency, fuel flexibility, and operational optimisation to levels that are far beyond anything else currently available. Its fuel consumption efficiency in its diesel version is as low as 165g/kWh. 

It comes in three alternative versions; Diesel, Dual-Fuel (DF) and Spark-Ignited Gas (SG). The multi-fuel capabilities that the Wärtsilä 31 brings to the market extend the possibilities for operators to utilise different qualities of fuels, from very light to very heavy diesel, and a range of different qualities of gas.

The increases in fuel efficiency and fuel flexibility are matched by significant reductions in maintenance costs. For example, the first service on the Wärtsilä 31 is required after only 8,000 running hours, whereas alternative standard marine engines require maintenance after 2,000 running hours.

The Wärtsilä 31 is available in 8V, 10V, 12V, 14V and 16V cylinder configurations. Among the many features of this engine are the latest developments in fuel injection systems, engine control systems, and charge air technologies. It is available for applications in mechanical drive installations, for producing electricity when coupled with a generator, for hybrid installations, as well as heavy duty installations or as an auxiliary engine.
