A forced lubrication system is used on diesel engines.
That means that lubrication takes place under pressure.
Pressure is created by the lubrication oil pump driven by the engine itself.
In some cases oil is supplied under pressure from the gravity tank.
In any case, oil is pumped from the lubricating oil sump or drain tank.
This tank is situated just below the crankcase.
It is longitudinal and connected to the crankcase.
The oil sump is part of the bedplate and is integrated into the ship’s double bottom.
The oil is supplied through the main supply line and through a series of filters.
From the supply line the oil is delivered to each main bearing and camshaft bearing.
The crankshaft, crankwebs, and bearings have bores for the delivery of oil from where oil can be delivered through connecting rod bores to the crosshead.
