The lubricating oil is stored in the oil sump under the engine. Return oil from the engine system is led back to the oil sump. The lubricating oil separator (if used) is connected directly to the engine oil sump.Complete lubricating system of W20V32 engine is described below with a detailed image.
Components in lubrication oil system of wartsila engine
Engine-driven oil pump, Electrically-driven pre lubricating oil pump, Cooler, Oil thermostatic valve, Automatic filter, Oil sump (built on the engine)
Details of lubricating oil system in engine:
The engine is provided with a lubricating oil pump (17), driven directly by the pump gear at the free end of the engine.
The oil flows through the lubricating oil automatic filter (3) to the main distributing pipe in the oil sump and then through the hydraulic jacks (in this respect acting as ordinary pipes) to the main bearings. Through bores in the connecting rods to the gudgeon pins (13), the piston skirt and piston cooling spaces are lubricated.
