| Types of Oil Cooled in a Marine System System Function Why it Needs Cooling Main Engine Lube Oil Lubricates pistons, bearings, camshaft Prevents breakdown under extreme heat from combustion and friction. Gearbox Oil Lubricates reduction gears Cools the oil heated by gear meshing and power transfer. Hydraulic Oil Powers winches, cranes, steering gear Maintains viscosity and prevents seal damage caused by heat from pressure. Piston Cooling Oil Cools the undersides of pistons Removes intense heat absorbed from combustion before the oil is recirculated. |
