Cylinder Lubrication System for Diesel Engines
Timed injection of cylinder oil onto the liner running surface of a large diesel engine, synchronised to crank angle so the charge lands where the rings will sweep it. The oil film carries the ring load and the alkaline reserve neutralises acid formed from sulphur in the fuel. SES holds the range as an authorised SKF distributor, covering injection points Several quills per cylinder, on the liner circumference; timing reference Crank angle encoder or camshaft pick-up; metering Positive-displacement piston element per quill; feed rate basis Grams of oil per kWh, adjustable in service. Executions include electronically timed cylinder lubricators, load-proportional metering controllers, quill and non-return valve assemblies, feed rate monitoring and alarm modules. It is specified most often into two-stroke crosshead main propulsion engines on dredgers and tugs and large four-stroke diesel gensets in captive power houses. Every part is genuine SKF through official channels, with designation, specification and options confirmed against your duty before it ships — supplied from Kolkata and our branch network, with breakdown cover that does not sit in an inbox.

Where it runs.
You will find Cylinder Lubrication System for Diesel Engines in the parts of a plant where this particular duty actually occurs. In practice that means two-stroke crosshead main propulsion engines on dredgers and tugs, large four-stroke diesel gensets in captive power houses, standby and emergency diesel sets at refineries and terminals, and equally diesel locomotive engines in plant railway workshops, marine auxiliary engines running on high-sulphur residual fuel. What links them is the duty rather than the machine name — function: Crank-angle timed cylinder oil injection. If your installation is not on that list it matters less than you would think: the operating condition decides the specification. Send us the load, the speed, the running temperature and the environment it runs in, and we will match it to the right execution in the SKF range and confirm what is in stock.
Specify it against the duty.
Specification here follows the operating condition, not the catalogue. Fuel sulphur content changes between bunkers or batches — A controller that lets you trim feed rate against fuel sulphur. Leave a high-sulphur feed rate running on low-sulphur fuel and unreacted alkaline additive builds hard deposits behind the top ring. Engine spends long periods at part load or slow steaming — Load-proportional metering with a defined minimum feed floor. Feed that falls linearly with load leaves the liner dry at the top dead centre reversal point, and cold corrosion starts as a polished band. Existing engine with mechanical lubricators being upgraded — An electronically timed unit that retains the original quill positions. Moving injection points on a proven liner wear pattern creates a fresh set of problems to diagnose. Where two of those apply at once, specify for the harsher of the two — under-specifying is what puts the part back on the bench a month later. Send us the duty and we will confirm the execution.
Ordering this from SES.
Pull and inspect the quills at every scheduled liner check. One blocked non-return valve leaves a dry sector on the liner, and the scuff mark it produces will be blamed on the oil for months before anyone finds the real cause.
