#cylinderoil #lubrication The Exhaust chamber of the engine is where all the power is generated. Hence, it is crucial to maintain lubrication supply into these areas. This is maintained by a marine engine cylinder lubrication system, which supplies lube oil through quills into the lines.

The supply of oil (timing) may vary depending upon the manufacturer, type of engine, and the fuel used in the combustion chamber.
