Main Engine 4-Stroke · Main Engines (4-Stroke)
This marine engine operates on a 4-stroke, turbocharged, and intercooled direct injection principle, designed for efficient combustion of both diesel and dual-fuel options. The Wärtsilä 12VW20DF, part of the Wärtsilä W20DF family, delivers a power output of 1296 kW at 1200 rpm. It features a bore and stroke of 200 mm and 280 mm respectively, with each cylinder having a capacity of 8.8 liters. The engine runs on a combination of LNG and heavy fuel oil (HFO) in a dual-fuel configuration, offering flexibility in operation and environmental benefits. Continuous monitoring of the balancing shaft bearings and turbine cooler temperatures helps prevent significant damage due to overheating or wear, as outlined by Wärtsilä. Additionally, regular inspections of cylinder liners and fuel injection components help maintain optimal performance and longevity.
