Main Engine 4-Stroke · Main Engines (4-Stroke)
Crew and engineers on board vessels rely heavily on high-performance marine engines to ensure reliable operation and efficiency. Wärtsilä's 12VW32 Ammonia engine stands out as a robust solution for modern maritime applications. This dual-fuel engine can run on ammonia or marine diesel oil, offering versatility and environmental compliance. With a powerful output of 3720 kW at 750 RPM, it is designed to meet the demanding requirements of various vessel types. The V-shaped configuration and 4-stroke operation provide efficient performance, while the bore and stroke dimensions are 320 mm and 400 mm, respectively. Each cylinder displaces 17 liters, contributing to its overall power and efficiency. The engine is turbocharged with an intercooler to enhance combustion efficiency and reduce emissions, meeting IMO Tier II standards. Regular maintenance checks, including visual inspections of piston rings, monitoring cylinder cooling water temperatures, and ensuring proper lubrication, are crucial for maintaining optimal performance and preventing common failures such as cold corrosion and fuel injection nozzle coking.
