Cold Weather Operation
Perkins Diesel Engines can operate effectively in
cold weather. During cold weather, the starting and
the operation of the diesel engine is dependent on
the following items:
•
The type of fuel that is used
•
The viscosity of the engine oil
•
The operation of the glow plugs.
The purpose of this section will cover the following
information:
•
Explain potential problems that are caused by cold
weather operation.
•
Suggest steps which can be taken in order to
minimize starting problems and operating problems
when the ambient air temperature is colder than
0to−55 °C (32 to −67 °F).
The operation and maintenance of an engine in
freezing temperatures is complex. This is because
of the following conditions: the unlimited differences
in weather conditions, engine applications, and
the supplies that are available in your area. These
factors and recommendations from your Perkins
dealer or your Perkins distributor are based on past
proven practices. The information that is contained in
this section should be combined in order to provide
guidelines for cold weather operations.
Hints for Cold Weather Operation
•
If the engine will start, operate the engine until a
minimum operating temperature of 71 °C (160 °F)
is achieved. Achieving operating temperature will
help prevent the intake valves and exhaust valves
from sticking.
•
The cooling system and the lubrication system
for the engine do not lose heat immediately upon
shutdown. This means that an engine can be shut
down for a few hours and the engine can still have
the ability to start readily. If the engine is shut
down for at least eight hours, the engine should be
considered cooled to outsid e temperature.
•
Install the correct lubricant in each compartment
before the beginning of cold weather.
•
Check all rubbe
r parts (hoses, fan drive belts, etc)
weekly.
•
Check all elec
trical wiring and connections for any
fraying or damaged insulation.
•
Keep all batte
ries fully charged and warm.
•
Fill the fuel tank at the end of each shift.
•
Check the air cleaners and the air intake daily.
Check the air intake more often when you operate
in snow.
Personal inj
ury or property damage can result
from alcohol or starting fluids.
Alcohol or st
arting fluids are highly f lammable and
toxic and if improperly stored could result in injury
or property da mage.
Do not use aerosol types of starting aids such as
ether. Such use could result in a n explosion and
personal injury.
•
For jump starting with cables in cold weather,
refer to the Operation and Maintenance Manual,
“Starting with Jump Start Ca bles.” for instructions.
Viscosity of the Engine Lubrication
Oil
Correct engine oil viscosity is essential. Oil viscosity
affects the amount of torque that is needed to
crank the engine. Refer to this Operation and
Maintenance Manual, “Fluid Recommendations” for
the recommended viscosity of oil.
Recommendations for the Coolant
Provide cooling system protection for the lowest
expected outside temperature. Refer to this Operation
and Maintenance Manual, “Fluid Recommendations”
for the recommended coolant mixture.
In cold weather, check the coolant often for the
correct glycol concentration in order to ensure
adequate freeze protection.
Engine Block Heaters
Engine block heaters (if equipped) heat the
engine jacket water that surrounds the combustion
chambers. This provides the following functions:
