Yanmar N18 Lubricator
Mega Marine supplies genuine and reconditioned lubricator for Yanmar N18 marine engines, along with complete engines and a comprehensive range of spare parts. Fast RFQ response and global delivery.
The cylinder oil lubricator delivers precisely metered doses of specially-formulated cylinder lubricating oil directly to the liner surface within the piston ring zone. Modern systems — including Alpha lubricators and electronically-controlled variants — time oil injection to coincide with ring passage over the quill holes for maximum efficiency. Cylinder oil has high total base number alkalinity to neutralise sulfuric acid formed during combustion of high-sulfur heavy fuel oil.
Function in the Engine
Delivers metered cylinder oil to the liner surface at the piston ring zone on each engine cycle, neutralises sulfuric acid formed during heavy fuel combustion to prevent cold corrosion of liner and rings, maintains the oil film between piston rings and liner bore to reduce wear rates.
About the Yanmar N18

Common Issues Requiring Replacement
Blockage of oil delivery quills by carbon deposits or debris, sticking or worn check valves allowing combustion gas back-flow, incorrect oil dosage rate causing either oil-starved liner wear or excessive consumption and fouling, pump element wear reducing delivery pressure and consistency.
