Main Engine 4-Stroke · Main Engines (4-Stroke)
A medium-speed marine diesel engine, the 8L M601C from Caterpillar MaK, offers robust performance and reliability for heavy-duty maritime applications. With eight cylinders arranged in an L configuration, this engine has a bore of 580 mm and a stroke of 600 mm, delivering a power output of 8,000 kW at 375 rpm. The M601C is designed to operate on heavy fuel oil (HFO) but can also run on diesel, gas, or as a dual-fuel capable engine. Its mechanical heavy-duty trunk piston technology ensures efficient operation and durability. Despite its discontinuation in 2022, the 8L M601C remains a legacy model trusted for its performance and fuel efficiency, with a specific fuel oil consumption (SFOC) of 125 g/kWh or 124 g/PSh when optimized. Common maintenance concerns include wear on the camshaft bearings, crankshaft bearings, cylinder liners, piston rings, and exhaust valves, which require regular inspections and monitoring to ensure optimal performance and longevity.
