The technology group Wartsila's highly successful and super-efficient Wartsila 31DF dual-fuel engine is being upgraded to increase even further its power output.
The higher power output will be available within the same dimensions as previously, thereby delivering greater performance within the same physical footprint. At the same time, the already low level of exhaust gas emissions is being improved to heighten even further the engine's sustainability factor.The Wartsila 31 engine was introduced in 2015 and recognised by
The power upgrade will result in the current output range of 4.2 to 11 MW, being increased to a range of 4.6 to 12 MW with 600 kW/cylinder at 750 rpm, and 580 kW/cylinder at 720 rpm. The new development also lowers the level of greenhouse gas emissions to a point where a typical ferry can reduce its emissions by as much as 750 tons per annum, corresponding to the average output from 163 cars.
'This power upgrade to the Wartsila 31DF represents significant added value to our customers,' says
Since its introduction, more than 100 Wartsila 31 engines have been sold, and in excess of 60,000 field operating hours have been accumulated.
'Sustainable power production is at the heart of Wartsila's product development strategy, and with all sectors of the global economy looking for ways to combat climate change, optimising efficiency and lowering emissions is of critical importance. Internal combustion engines will play a crucial role in balancing the future energy mix, and hence we are focusing strongly on continuously developing our engines to achieve better power generation performance, greater cost-efficiency, and to accept new fuels. Powering up the W31DF is one good example,' adds
