Another important fuel property which can affect cold
start and operation of diesel engine is Cetane
number. Detail and requirements of this property are
given in this Operation and Maintenance Manual,
“Fluid Recommendations”.

Fuel

Components
in
Cold

Fuel
Tanks
Condensation
can
form
in
partially
filled
fuel
tanks.
Top
off
the
fuel
tanks
after
you
operate
the
engine.
Fuel
tanks
should
contain
some
provision
for
draining
water
and
sediment
from
the
bottom
of
the
tanks.
Some
fuel
tanks
use
supply
pipes
that
allow
water
and
sediment
to
settle
below
the
end
of
the
fuel
supply
pipe.
Some
fuel
tanks
use
supply
lines
that
take
fuel
directly
from
the
bottom
of
the
tank.
If
the
engine
is
equipped
with
this
system,
regular
maintenance
of
the
fuel
system
filter
is
important.
Drain
the
water
and
sediment
from
any
fuel
storage
tank
at
the
following
intervals:
weekly,
service
intervals
and
refueling
of
the
fuel
tank.
Draining
will
help
prevent
water
and/or
sediment
from
being
pumped
from
the
fuel
storage
tank
and
into
the
engine
fuel
tank.
Fuel
Filters
After
you
change
the
fuel
filter,
always
prime
the
fuel
system
in
order
to
remove
air
bubbles
from
the
fuel
system.
Refer
to
the
Operation
and
Maintenance
Manual
in
the
Maintenance
Section
for
more
information
on
priming
the
fuel
system.
The
micron
rating
and
the
location
of
a
primary
fuel
filter
is
important
in
cold-weather
operation.
The
In-
line
filter,
primary
fuel
filter,
and
the
fuel
supply
line
are
the
most
common
components
that
are
affected
by
cold
fuel.
Fuel
Heaters
Note:
The
OEM
may
equip
the
application
with
fuel
heaters.
If
so,
the
temperature
of
the
fuel
must
not
exceed
73
°C
(163
°F)
at
the
fuel
transfer
pump.
The
fuel
heater
should
be
installed
before
the
electric
lift
pump.
For more information about fuel heaters (if equipped),
refer to the OEM information.

Diesel
Exhaust
Fluid
in
Cold
Weather
Due
to
the
freezing
point
of
Diesel
Exhaust
Fluid
(DEF)
the
aftertreatment
system
is
equipped
with
electrically
heated
DEF
lines.
The
system
also
has
a
coolant
heated
element
in
the
DEF
tank.
During
periods
of
weather
in
which
DEF
can
freeze
the
application
should
be
stood
on
level
ground
when
not
in
use.
DEF
can
start
to
freeze
at
−11°
C
(12.2°
F).
Note:
At
certain
angles
DEF
can
cover
the
DEF
filler
cap.
If
the
DEF
freezes,
the
DEF
tank
vent
could
block.
A
blocked
vent
in
the
DEF
tank
assembly
will
cause
operational
difficulties.
For
information
on
DEF
refer
to
this
Operation
and
Maintenance
Manual,
“Fluid
Recommendations”.
