This maritime equipment belongs to the category of marine propulsion engines. The MAN Energy Solutions 9L32/44CR-GS-60Hz is a powerful marine diesel engine designed for efficient propulsion and power generation on ships. With a power output of 4320 kW at 900 rpm, this engine runs on heavy fuel oil (HFO) or marine diesel oil (MDO) and is configured in a 9-cylinder inline layout. The engine's bore and stroke dimensions are 320 mm and 440 mm, respectively, delivering a robust performance while adhering to IMO Tier II and III emissions standards. The common issues that may arise include turbocharger fouling due to carbon buildup, cylinder head gasket wear, common rail system failures, bearing wear, and cylinder liner and piston wear. Regular maintenance, such as periodic inspections and cleaning, is crucial to prevent these issues and ensure optimal engine performance.

For marine equipment hardly any maker or authorised dealer will name a price while the vessel is unknown. With the vessel details, availability and price can be settled faster; without them we may have to ask first, which costs a few days. If you are not allowed to name the vessel, a photo of the rating plate is enough — attach it below or send it as a reply to our confirmation e-mail.
