Lubricating oil for an engine is stored in the bottom of
the crankcase, known as the sump, or in a drain tank
located beneath the engine. The oil is drawn from this
tank through a strainer, one of a pair of pumps, into one
of a pair of fine filters. It is then passed through a
cooler before entering the engine and being distributed
to the various branch pipes.

The scavenging oil pump is a separate pump which
takes oil from the engine oil pan sump and pumps it
through the off-engine lube oil filter and cooler
assemblies before returning to supply the strainer
housing. All the pumps are driven from the accessory
gear train at the front of the engine.
04 Oil System
The main lubricating oil system supplies oil under
pressure to most of the moving parts of the engine. Oil
is pumped into the main oil manifold which is located
above the crankshaft, and extends the length of the
engine. Maximum oil pressure is limited by a relief
valve in the passage between the pump and the main oil
manifold.

The Piston Cooling Oil System is designed to cool the pistons, which are
subjected to high temperatures due to combustion. The benefits of Piston
Cooling are the following:
1. Reduced Piston Temperature: This helps prevent piston seizure
and damage due to excessive heat.
2. Improved Combustion: Cooler pistons can help maintain optimal
combustion chamber temperatures, leading to better fuel efficiency and
reduced emissions.
3. Extended Engine Life: By reducing stress on the pistons, piston
cooling contributes to a longer engine lifespan.

The "Soak Back" or "Turbo Lube" system plays a critical role in ensuring the
proper operation and longevity of the turbocharger. By providing lubrication
and cooling, it prevents damage to the turbocharger, which is essential for
engine performance and efficiency.
Here are some of the purpose of Soak back or turbo Lube system:
1. Turbocharger Lubrication: The turbocharger's bearings, shaft, and other
moving parts require lubrication to prevent wear and seizure.
2. Turbocharger Cooling: The turbocharger, especially the turbine section, can
reach extremely high temperatures due to exhaust gas flow. Cooling is
essential to prevent damage.
A lube oil separator is a device used in systems such as marine
engines, power plants, and industrial machines to remove impurities
from lubricating oil. This helps maintain the quality of the oil,
extends the lifespan of machinery, and ensures efficient performance.
The separator works on the principle of centrifugal force, where
heavier contaminants (like water, sludge, and metal particles) are
forced to the outer edge of the separator bowl, while the cleaned oil
is collected in the center and recirculated.
A hot oil detector in a lube oil system is used to
monitor the temperature of the lubricating oil,
particularly in machinery or engines. Its primary
function is to detect abnormal temperature rises, which
may indicate issues like excessive friction, oil
degradation, or component failure. If the oil gets too
hot, it can lose its lubricating properties, leading to
increased wear, potential mechanical damage, or even
system failure.
