5.2.2 Lubricating quill
The lubricating quills spray oil onto the cylinder liner wall. The lubricating quills are installed on the
circumference of the cylinder liner.
The cylinder lubricating pump supplies a specified quantity of cylinder oil at high pressure through
the cylinder oil inlet (006, Figure 5-7) into the lubricating quills. The non-return valve (009) opens
and the cylinder oil flows out of the nozzle tip (003) and the lubricating point (004) as a spray.
Some of the cylinder oil flows into the grooves of the cylinder liner wall. The non-return valve (009)
prevents the exhaust gas to flow back into the oil pipe.
