Designed to deliver high efficiency and environmental performance, Wärtsilä’s 16VW46TS-DF is a dual-fuel engine that operates on both LNG and HFO. This V-configured, 4-stroke engine features a bore of 460 mm and a stroke of 580 mm, with 16 cylinders delivering a remarkable power output of 10720 kW at 600 rpm. The engine’s advanced design includes a two-stage turbocharging system with high-electronic common-rail injection, contributing to its superior thermal efficiency of up to 52% in gas mode. It meets IMO Tier III emissions standards without the need for exhaust aftertreatment, and boasts low methane slip and carbon dioxide emissions. The 16VW46TS-DF is built for robust operation across a wide temperature range from -55°C to +55°C and has been in production since 2022. Common maintenance concerns include monitoring the turbocharger oil pressure and flow, inspecting the crankcase for contamination, checking valve stems for corrosion, and ensuring proper piston ring condition. Regular checks and maintenance can help mitigate these issues and ensure optimal performance.
