Auxiliary Engine (Generator Set) · Auxiliary Engines
In shipboard applications, marine engines like the Wärtsilä 6LW31-GS-60Hz often operate in low-load conditions, which can lead to poor combustion and the accumulation of carbon deposits in cylinders, turbocharger fouling, and economizer fouling. This 6-cylinder, 4-stroke engine delivers a maximum power output of 1770 kW at 900 rpm and is designed to run on heavy fuel oil (HFO), marine diesel oil (MDO), and can also operate in a dual-fuel mode with natural gas. The engine features a two-stage turbocharging system with intercooling, enhancing its efficiency and performance. It is equipped with a common rail direct injection fuel system, which is known for its robustness and reliability. The Wärtsilä 6LW31-GS-60Hz is in production from 2024 to the present and has been in service since 2015, with over 1,000 MW installed globally and more than 1 million running hours logged.
