Main Engine 2-Stroke · Main Engines (2-Stroke)
This powerful maritime engine, the 6W-X82 from WinGD, offers exceptional performance and efficiency for modern shipping demands. With a power output of 27060 kW, this six-cylinder, two-stroke engine operates at an RPM range of 58 to 84, making it ideal for low-speed ship propulsion. The bore and stroke dimensions are 820 mm and 3375 mm, respectively, contributing to its robust design. The engine is versatile in fuel options, supporting heavy fuel oil (HFO), marine diesel oil (MDO), liquefied natural gas (LNG), methanol, and ammonia, with specific configurations tailored for each fuel type. For instance, the X82-2.0 variant achieves a mean effective pressure of 22 bar at rated power, while the dual-fuel X82DF-1.0 operates at 17.3 bar when running on LNG. The engine’s design emphasizes efficiency, with features like a long stroke for enhanced performance and reduced cylinder distance of 1440 mm compared to its predecessor. Common maintenance concerns include potential wear in piston cooling oil channels under high loads, contamination in the scavenging system, and methane slip during dual-fuel operation, which can be mitigated with regular inspections and advanced control systems like iCER.
