Main Engine 4-Stroke · Main Engines (4-Stroke)
Diesel engines like the 16VH35/40 are commonly found powering large ships, where they operate reliably over long durations at moderate speeds. With a power output of 8400 kW and a bore and stroke of 350 mm and 400 mm respectively, this engine is well-suited for marine vessels requiring substantial propulsion. It features a V-configuration with 16 cylinders, running at 720 rpm and fueled by heavy fuel oil (HFO) or marine diesel oil (MDO). The engine's specific fuel oil consumption (SFOC) is 177 g/kWh at 100% maximum continuous rating (MCR), and 174 g/kWh at 85% MCR. It is certified to IMO Tier III standards and has received type approval from nine classification societies. Common maintenance issues include cylinder cover wear and surface corrosion, water contamination in the crankcase leading to acid formation and wear, and abrasive particle wear on piston rings and liners. Regular inspection and reconditioning are recommended to ensure optimal performance and longevity.
