8L27/38-GS-60Hz

Designed for robust performance in marine applications, the 8L27/38-GS-60Hz is a powerful and reliable engine that meets the demanding needs of modern maritime operations. This model delivers an impressive 2720 kW of power at 900 rpm, making it suitable for both propulsion and generator sets. The 8L27/38-GS-60Hz is equipped with a high-efficiency MAN TCR constant-pressure turbocharger system, enhancing its overall efficiency and performance. It can operate on Heavy Fuel Oil (HFO), Marine Diesel Oil (MDO), and Marine Gas Oil (MGO), with dual-fuel DF versions available for methanol, providing flexibility in fuel choice. The engine's robust design includes a bore of 270 mm and a stroke of 380 mm, arranged in an inline configuration. It features a compression ratio of 15.9 and can achieve a mean effective pressure (MEP) of 23.5 bar. The 8L27/38-GS-60Hz also meets IMO Tier II emission standards, with the option to comply with IMO Tier III when equipped with selective catalytic reduction (SCR). Despite its powerful output, the engine maintains efficient fuel consumption, with specific fuel oil consumption (SFOC) values of 188 g/kWh at 100% MCR and 185 g/kWh at 85% MCR for HFO. Common issues to monitor include fuel oil contamination, which can lead to bearing wear, and fuel injector pressure drops. Additionally, thermal fatigue cracking in the piston crown and cylinder liner wear near top dead center (TDC) are critical areas that require regular inspection. The 8L27/38-GS-60Hz remains a trusted choice for marine operators, with legacy engines still in service worldwide.
