DU-Wärtsilä 2-Stroke Engines
As the 2-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 engines, widely 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. This type of engine with the electronic control will be the main stream of the large 2-stroke marine engine from now on.
DU-S.E.M.T. Pielstick 4-Stroke Engines
The 4-stroke engines, DU-S.E.M.T. Pielstick type, have lower engine height compared with the low speed engine 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.
