DU-Wärtsilä 2-Stroke Engines
As the two-stroke engine, DU-Wärtsilä (ex. DU-SULZER) type diesel engines are running successfully as the prime mover of marine transportation, such as, large oil tankers, container ships, bulk carriers.
The RT-flex and X engines, applied presently, have common-rail systems with the electronic fuel injection control system and high operating flexibility to adapt to various engine running conditions and regulation of NOx emission. These type engines with the electronic control will be the main stream of the large two-stroke marine engine from now on.DU-S.E.M.T. Pielstick 4-Stroke Engines
The four-stroke engines, DU-S.E.M.T. Pielstick type, have lower engine height to compared with the low-speed 2-stroke engines and are widely adopted for cruise ships, car ferries, Ro-Ro ships where compact size of the engine is required. This type of engine is also utilized for stationary electric power generation plant in isolated islands or inland areas.
Dual Fuel Engines (low-Pressure and pre-mixed lean burn technology)
Driven by environmental awareness, IMO (International Management organization) determined to enhances emission regulations. The interest in gas as fuel for shipping is increasing to fulfill the rigid regulation.
IHI, WinGD, and DU developed dual fuel engines adapted to pre-mixed learn burn technology with a strong assosiation and now We put confidently “X-DF” engines into the marine market.2-Stroke Engines, 4-Stroke Engines, Dual Fuel Engines
