7S50ME-C8.5

The Hyundai 7S50ME-C8.5 is a 7‑cylinder inline low‑speed two‑stroke main engine with electronic ME‑C control, offering high fuel flexibility and optimized combustion for mid‑size merchant vessels; source-listed power 11620.0 kW. The supplied category identifies it as Main Engine 2-Stroke, and it is normally installed in the main engine room as the principal propulsion prime mover, normally connected directly or through the shaft line to the propeller. In that role, its primary purpose is to convert fuel energy into low-speed or marine propulsion torque for continuous vessel propulsion. Two-stroke crosshead main engines use separate crosshead and crankcase arrangements with scavenge-air and cylinder-lubrication systems, distinguishing them from trunk-piston four-stroke engines. Within the supplied list, this entry is distinguished from neighbouring variants by its model designation and the explicitly listed power; no further model-specific difference is stated in the source. No additional performance, approval or construction detail is inferred from the model code beyond the information supplied in the source record. For exact ratings, dimensions, settings, capacities, materials and variant-specific limits, refer to the manufacturer documentation for the exact figure.
