Did you know
- Mitsui E&S DU (Diesel United) has a long heritage, with a technical partnership established in 1948 with Sulzer Brothers, now WinGD. The first Sulzer-type two-stroke diesel engine was completed in 1950.
- Mitsui E&S DU offers DU-WinGD two-stroke engines, which are distinct from the MITSUI-MAN B&W engines also produced by the Mitsui E&S Group. The DU-WinGD engines are primarily used as prime movers for large vessels like oil tankers, container ships, and bulk carriers, while their four-stroke DU-S.E.M.T. Pielstick engines are chosen for applications requiring a lower engine height, such as cruise ships and ferries.
- The DU-WinGD engines are known for their common-rail systems with electronic fuel injection control, offering high operating flexibility and compliance with NOx emission regulations. They are also at the forefront of dual-fuel technology, including X-DF engines adapted for pre-mixed lean burn technology, addressing the increasing interest in gas as a marine fuel for environmental compliance.
| Model | Fuel Type | Application | Key Technology |
|---|---|---|---|
| Mitsui-Sulzer-DU (DU-WinGD 2-Stroke) | Diesel, LNG (X-DF) | Large oil tankers, container ships, bulk carriers | Common-rail electronic fuel injection, X-DF dual fuel (low-pressure, pre-mixed lean burn) |
| MITSUI-MAN B&W (2-Stroke) | Diesel, Methanol, Methane, Ethane, LPG, Ammonia (under development) | Various ocean-going vessels, ferries, RORO vessels | Dual fuel capabilities (ME-LGIM, ME-GI, ME-GIE, ME-LGIP), EGR, SCR |
| DU-S.E.M.T. Pielstick (4-Stroke) | Diesel | Cruise ships, car ferries, Ro-Ro ships, stationary power generation | Compact size, lower engine height |
