Main Engine 4-Stroke · Main Engines (4-Stroke)
Designed for efficient and reliable operation on modern LNG-fueled vessels, the 16VW32SG engine delivers a robust 5360 kW of power at 750 RPM. This V-configuration, 4-stroke engine features a bore of 320 mm and a stroke of 400 mm, making it well-suited for demanding marine applications. Each cylinder contributes consistently with 325 kW, ensuring balanced performance across all configurations. The 16VW32SG is turbocharged with an intercooler to enhance efficiency and power output, while its Mean Effective Pressure (MEP) of 24 bar at 1000 RPM further underscores its high-performance capabilities. The engine's use of LNG as a spark-ignited fuel aligns it with stringent environmental standards, including IMO Tier II (MARPOL 73/78 Annex VI). Despite its powerful output, the 16VW32SG maintains an SFOC of 186-192 g/kWh at ISO conditions and 85% load. Common operational challenges include issues like piston ring wear under continuous low-load operation, which can be mitigated through regular visual inspections and monitoring of cylinder oil chemistry. Cold corrosion in cylinder liners during low-load operations is another concern, addressed by maintaining appropriate cylinder cooling water temperatures and using the right cylinder oil. The 16VW32SG's robust design and advanced features make it a reliable choice for modern maritime propulsion systems, ensuring both performance and environmental compliance.
