Main Engine 4-Stroke · Main Engines (4-Stroke)
Designed to deliver high efficiency and reliability, the Wärtsilä 10LW32 is part of the W32 family, featuring a robust 4-stroke configuration with a bore of 320 mm and a stroke of 400 mm. This powerful engine produces 3400 kW at 750 rpm, making it suitable for a variety of marine applications. It operates on heavy fuel oil (HFO) or marine diesel oil (MDO), thanks to its versatile fuel injection system, which employs common rail direct injection for precise and efficient combustion. The engine's two-stage turbocharging with intercooling further enhances performance and efficiency. Despite its advanced design, the 10LW32 is not immune to certain operational challenges. Low-load operation can lead to poor combustion and carbon deposit accumulation in cylinders and turbocharger fouling. Cylinder liner wear and scuffing are common issues that can be exacerbated by inadequate lubrication oil film and excessive cylinder temperature. The fuel injection system, while generally robust, requires careful maintenance, with high-pressure fuel pump overhaul intervals extended to 24,000 hours. Additionally, the risk of crankcase oil mist build-up due to carbonized lube oil and unburnt fuel residues remains a concern in marine diesel engines.
