Spark-ignited gas technology powers the Wärtsilä 16VW50SG, a high-performance engine designed for natural gas operation. This V-configured engine features 16 cylinders, each with a bore of 500 mm and a stroke of 580 mm. The displacement per cylinder is 17 liters, contributing to its total output of 15200 kW at 514 rpm. Turbocharged with an intercooler, the engine ensures efficient performance under various conditions. It meets IMO Tier II emission standards, making it suitable for environmentally conscious operations. The mean effective pressure is 25.5 bar at 900 RPM and 24 bar at 1000 RPM, while the piston speed reaches 9.6 m/s at 900 RPM and 10.7 m/s at 1000 RPM. The engine's specific fuel oil consumption (SFOC) ranges from 186 to 192 g/kWh under ISO conditions at 85% load. Common maintenance issues include piston ring wear, cold corrosion in cylinder liners, and turbocharger bearing wear, which require regular inspections and adherence to recommended operating practices to ensure optimal performance and longevity.
