Main Engine 4-Stroke · Main Engines (4-Stroke)
The engine operates on a 4-stroke cycle with dual-fuel capabilities, designed to run efficiently on LNG or heavy fuel oil (HFO), making it suitable for various maritime applications. Manufactured by Wärtsilä, the 6LW26DF model features a bore of 260 mm and a stroke of 320 mm, delivering 1110 kW at 1000 RPM. This engine is equipped with turbocharging and an intercooler system to optimize combustion efficiency and reduce emissions, adhering to IMO Tier II standards. Regular inspections are crucial to maintain performance; for instance, piston ring wear under low-load conditions can lead to peeling or whitening due to insufficient oil film, while cylinder liner glazing may result in a loss of crosshatch pattern, affecting engine operation.
