Main Engine 4-Stroke · Main Engines (4-Stroke)
This maritime diesel engine employs a constant pressure turbocharging system with intercooling to optimize performance and efficiency. Designed for heavy fuel oil (HFO) and marine diesel oil (MDO) operation, the MAN Energy Solutions 12V28/32S is a robust and versatile engine with a swept volume per cylinder of 19.7 dm³, delivering a total power output of 3720 kW at 750 rpm. The engine features a 4-stroke configuration with a bore and stroke of 280 mm and 320 mm, respectively. It achieves a compression ratio of 13.9:1 and a mean effective pressure (MEP) of 17.8 bar during maximum continuous rating (MCR) operations with MDO. Common maintenance concerns include charge air cooler fouling from oil and water deposits, leading to increased charge air temperature and pressure drop, and exhaust valve erosion from corrosive compounds in heavy fuel oil. Regular checks for these issues are crucial to maintain optimal engine performance and longevity.
