Wärtsilä is launching a more powerful version of its well established 20 diesel engine to allow vessels to accommodate greater payloads and faster speeds with a similar low fuel consumption.

This new development features an increased cylinder output of 220kW that will increase the engine's power density, thereby improving the bollard pull capacity for tugs and support vessels.

"The new Wärtsilä 20 engine has the best power-to-weight ratio on the market in its segment. This provides an exciting value proposition for owners of ships where a light yet powerful engine is an advantage," said Stefan Wiik, Vice President, Engines, Wärtsilä Marine Solutions.

By increasing the output per cylinder from 185kW to 220kW, it follows that fewer cylinders will be needed when installed in 60Hz generating sets. This means that a lighter and more compact generating set is possible within the 1.3 to 2 MW merchant auxiliary segment.

Refinement

Since the new engine is a refinement of the existing Wärtsilä 20 engine, there is a high level of compatibility with the spare parts needed with maintenance procedures for the most part unchanged.

The Wärtsilä 20 has proven its robustness and reliability with more than 6000 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.

This new improved version will be officially launched at the Marintec conference and exhibition in Shanghai, China, from 5 to 8 December.
