Engine
Operation
Correct
operation
and
maintenance
are
key
factors
in
obtaining
the
maximum
life
and
economy
of
the
engine.
If
the
directions
in
the
Operation
and
Maintenance
Manual
are
followed,
costs
can
be
minimized
and
engine
service
life
can
be
maximized.
The
time
that
is
needed
for
the
engine
to
reach
normal
operating
temperature
can
be
less
than
the
time
taken
for
a
walk-around
inspection
of
the
engine.
The
engine
can
be
operated
at
the
rated
rpm
after
the
engine
is
started
and
after
the
engine
reaches
operating
temperature.
The
engine
will
reach
normal
operating
temperature
sooner
during
a
low
engine
speed
(rpm)
and
during
a
low-power
demand.
This
procedure
is
more
effective
than
idling
the
engine
at
no
load.
The
engine
should
reach
operating
temperature
in
a
few
minutes.
Avoid
excess
idling.
Excessive
idling
causes
carbon
buildup,
andengine
slobber.
These
issues
are
harmful
to
the
engine.
Gauge
readings
should
be
observed
and
the
data
should
be
recorded
frequently
while
the
engine
is
operating.
Comparing
the
data
over
time
will
help
to
determine
normal
readings
for
each
gauge.
Comparing
data
over
time
will
also
help
detect
abnormal
operating
developments.
Significant
changes
in
the
readings
should
be
investigated.
Engine
Operation
and
the
Aftertreatment
System
The
exhaust
gases
and
hydrocarbon
particles
from
the
engine
pass
through
Diesel
Oxidation
Catalyst
(DOC).
Some
of
the
gasses
and
matter
are
oxidized
as
the
gasses
pass
through
the
DOC.

Engaging
the
Driven
Equipment
1.
Operate the engine at one-half of the rated rpm,
when possible.
2.
Engage the driven equipment without a load on the
equipment, when possible.
Interrupted starts put excessive stress on the drive
train. Interrupted starts also waste fuel. To get the
driven equipment in motion, engage the clutch
smoothly with no load on the equipment. This
method should produce a start that is smooth and
easy. The engine rpm should not increase and the
clutch should not slip.
3.
Ensure that the ranges of the gauges are normal
when the engine is operating at one-half of the
rated rpm. Ensure that all gauges operate
properly.
4.
Increase the engine rpm to the rated rpm. Always
increase the engine rpm to the rated rpm before
the load is applied.
5.
Apply the load. Begin operating the engine at low
load. Check the gauges and equipment for proper
operation. After normal oil pressure is reached and
the temperature gauge begins to move, the engine
may be operated at full load. Check the gauges
and equipment frequently when the engine is
operated under load.
Extended operation at low idle or at reduced load
may cause increased oil consumption and carbon
buildup in the cylinders. This carbon buildup
results in a loss of power and/or poor
performance.

Fuel
Conservation
Practices
The
efficiency
of
the
engine
can
affect
the
fuel
economy.
Perkins
design
and
technology
in
manufacturing
provides
maximum
fuel
efficiency
in
all
applications.
Follow
the
recommended
procedures
to
attain
optimum
performance
for
the
life
of
the
engine.
• Avoid spilling fuel.
Fuel expands when it is warmed up. The fuel may
overflow from the fuel tank. Inspect fuel lines for
leaks. Repair the fuel lines, as needed.
• Be aware of the properties of different fuels. Use
only the recommended fuels. Refer to the
Operations and Maintenance Manual, “Fuel
Recommendations” for further information.
• Avoid unnecessary idling.
Shut off the engine rather than allowing the engine to
idle for long periods of time.
• Observe the service indicator frequently. Keep the
air cleaner elements clean.
