Water temperat
ure regulator which regulates the
engine coolant temperature

Gear-driven r
otor type oil pump
•
Oil cooler
The engine lubricating oil is supplied by a rotor type
oil pump. The engine lubricating oil is cooled and the
engine lubr
icating oil is filtered. The bypass valve
can provide unrestricted flow of lubrication oil to
the engine if the oil filter element should become
plugged.
Engine efficiency, efficiency of emission controls, and
engine per
formance depend on adherence to proper
operation and maintenance recommendations.
Engine performance and efficiency also depend on
the use of r
ecommended fuels, lubrication oils, and
coolants. Refer to this Operation and Maintenance
Manual, “Maintenance Interval Schedule” for more
informat
ion on maintenance items.
Aftertre
atment System
The aftertreatment system is approved for use by
Perkins
. In order to be emission-compliant only the
approved Perkins aftertreatment system must be
used on a Perkins engine.
Clean Emission Module (CEM)
The CEM
comprises of two main components in a
single unit, the Diesel Oxidation Catalyst DOC and
the Diesel Particulate Filter DPF. The function of the
CEM is
to ensure that the engine exhaust meets
the required emissions regulation for the country of
operation.
Theengineexhaustisconnectedbyaflexible pipe to
the CEM. The exhaust gases pass through the DOC
in or
der to remove contaminants, carbon monoxide,
and hydrocarbons. The exhaust gases then enter the
DPF where any particulate matter soot and ash will
be tr
apped.
The CEM uses a passive regeneration process to
ens
ure that normal operation of the engine removes
the soot. The soot is removed at an equal rate of
which the soot is captured. The ash remains in the
DPF
and must be removed at an engine overhaul.
En
gine Service Life
Engine efficiency and maximum utilization of engine
pe
rformance depend on the adherence to proper
operation and maintenance recommendations. In
addition, use recommended fuels, coolants, and
lu
bricants. Use the Operation and Maintenance
Manual as a guide for required engine maintenance.
Expected engin
e life is generally predicted by the
average power that is demanded. The average power
that is demanded is based on fuel consumption of the
engine over a p
eriod. Reduced hours of operation
at full throttle and/or operating at reduced throttle
settings result in a lower average power demand.
Reduced hour
s of operation will increase the length of
operating time before an engine overhaul is required.
Aftermarket Products and Perkins
Engines
Perkins does not warrant the quality or performance
of non-Perk
ins fluids and filters.
When auxiliary devices, accessories, or consumables
(filters, a
dditives, catalysts,) which are made by other
manufacturers are used on Perkins products, the
Perkins warranty is not affected simply because of
such use.
However, failures that result from the installation
or use of o
ther manufacturers devices,
accessories, or consumables are NOT Perkins
defects. Therefore, the defects are NOT covered
under th
e Perkins warranty.
