6L28/33D-GS-60Hz

Marine engineers and operators rely on robust, efficient engines to ensure reliable power generation and propulsion on board vessels. MAN Energy Solutions’ 6L28/33D-GS-60Hz is a prime example of this reliability. This engine delivers a continuous output of 1920 kW at 900 rpm, powered by marine diesel oil (MDO). Designed with six cylinders in an inline configuration, it operates on the four-stroke cycle and has a bore of 280 mm and a stroke of 330 mm. The genset rating is 1824 kW, with a kVA output of 2280 at a frequency of 60 Hz. Key features include MAN TCA turbochargers that automatically cut off the second turbocharger at part load to optimize efficiency. The engine has a compression ratio of 16.5:1 and is capable of handling both MDO and heavy fuel oil (HFO). It has passed type approval tests, ensuring compliance with IMO Tier II and Tier III standards. Regular maintenance checks are crucial for optimal performance, including inspecting the seawater cooling system strainer, turbocharger blades, fuel injectors, exhaust valves, and cylinder liners to prevent common issues such as clogging, fouling, wear, and carbon deposits.
