Wärtsilä 20 is a compact, lightweight marine engine. It offers fuel flexibility and reliable performance in genset and main engine applications. It is available in diesel and dual-fuel versions, and the dual-fuel version will switch between different fuels during operation smoothly, without power interruption.
Wärtsilä 20 offers outstanding flexibility, which makes it a great choice for generating sets in larger vessels and as a main engine for both mechanical and electric propulsion. The dual-fuel version is a great choice for many vessel types, including hybrid installations.
Ideal applications for the Wärtsilä 20 engine include:
The Wärtsilä 20 has proven its robustness and reliability with over 7500 engines delivered since its introduction to the market in the early 1990s. The engine can switch from MDO to HFO and vice versa without power interruption at any engine operation load.
The engine is available in cylinder configurations 4L, 6L, 8L, 9L with the power output ranging between 740 and 1980 kW at 900, 1000 and 1200 rpm.
The Wärtsilä 20DF is based on the well proven and reliable Wärtsilä 20 diesel engine introduced in the early 1990s. Because of its fuel flexibility, the Wärtsilä 20DF can be optimized for constant speed generating sets, as well as variable speed mechanical drives, for main engine applications.
The engine is available in cylinder configurations 6L, 8L, 9L with the power output ranging between 870 and 1755 kW at 900, 1000 and 1200 rpm.

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.
