Catalogue excerpts

The WARTSILA® 20 is a four-stroke diesel engine that can be run on light fuel oil (LFO) or heavy fuel oil (HFO). The engine can switch from LFO to HFO and vice versa without power interruption at any engine operational load. The Wartsila 20 has proven robustness and reliability, with over 6000 engines delivered since it was introduced to the market in the early 1990s. The Wartsila 20 covers the lower power range within the Wartsila diesel engine family. Typical application areas The Wartsila 20 is suitable for a broad range of applications. Thanks to its modular and compact design, the engine can be optimised for constant speed generating sets, as well as for variable speed with main engine mechanical drive applications. With its outstanding power-to-weight and power-to-space ratios, the Wartsila 20 provides various application options for different types of vessel. For example, in smaller ships, such as small cargo vessels, ferries or tug boats, it can be used as the mechanical drive prime mover. The Wartsila 20 is also an excellent generator set drive in both small and large vessels. Its flexibility in engine support arrangements provides an optimal foundation, either rigid or flexible, for numerous applications in both marine and land-based power solutions. Key benefits • Proven and reliable heavy fuel technology • Easy and cost-effective installation • Long overhaul intervals • Low exhaust gas emissions • Fuel economy over the entire engine operational range • Minimal consumables thanks to its modular design • Embedded automation system

Main technical data Wartsila 20 Rated power Operational features The Wartsila 20 is able to operate on different fuels, from the lowest viscosity of 1.8 cSt up to 730 cSt HFO (at 50 °C). The engine is also able to use low sulphur fuel oils (<0.1% S) set as standard by emission control area authorities. Environmental compliance The Wartsila 20 engine is fully compliant with the IMO Tier II exhaust emission regulations set out in Annex VI of the MARPOL 73/78 convention. The engine can also be equipped with an SCR catalyst, such as the Wartsila NOR (nitrogen oxide reducer), which can reduce NOX emissions...
