Wärtsilä 20 marine engines

Fuel flexibility and emission reduction The Wärtsilä 20 can operate on conventional liquid marine fuels (LFO, HFO or liquid biofuels) or LNG. Fuel switching takes place without loss of power or speed. For vessel operators, a fuel-flexible engine means that it is possible to comply with the ever-tightening emission regulations. At the same time, operators will have the option to choose fuel according to cost and availability. Adopting LNG as fuel can help you reduce greenhouse gas emissions significantly. To maximise the environmental benefits of LNG, it is important to minimise methane slip – the unburned methane that escapes into the atmosphere when LNG is burned as fuel. Wärtsilä 20DF is a great choice because it cuts methane slip in two ways. Its combustion chambers are designed to reduce methane slip, and its combustion controls have been optimised.
