Note: If the engine has not been run for several
weeks, fuel may have drained. Air may have moved
into the filter housing. Also, when fuel filters have
been changed, some air will be left in the filter
housing. Refer to the Operation and Maintenance
Manual, "Fuel System - Prime" (Maintenance
Section) for more information on priming the fuel
system.
During startup and light load operation on certain
standby generator set applications, white smoke and
wetness in the exhaust system may be experienced
in cold ambient conditions of below 7° C (45° F).
When a diesel engine is operated on light loads, the
engine does not reach and maintain the correct
operating temperature.
When the diesel engine runs below the designed
operating temperature for extended periods,
unburned fuel accumulates and that causes wetness
in the exhaust system. The following
recommendation will reduce the symptoms, but will
not fully eliminate the symptoms.
The recommendation to achieve increased cylinder
temperature of the engine is to apply a minimum load
of 30 percent to reduce white smoke and
accumulation of unburned fuel.
Selective Cylinder Cutout (SCC) (If
Equipped)
Selective Cylinder Cutout (SCC) is used to control
combustion during cold start and low load conditions
by only activating 3 cylinders during these conditions.
SCC helps maintain consistent power and reduction
in white smoke.
Ether Injection System (If
Equipped)
The ether injection system is controlled by the ECM.
The ECM monitors the coolant temperature, intake
air temperature, ambient air temperature, and
barometric pressure to determine when ether
injection is needed. At sea level, ether will be used if
any of the temperatures fails to exceed 0° C (32° F).
This temperature is subject to an increase as
barometric pressure increases.
Personal injury or property damage can result
from alcohol or starting fluids.
Alcohol or starting fluids are highly flammable
and toxic and if improperly stored could result in
injury or property damage.
Follow the procedure in this Operation and
Maintenance Manual, "Starting the Engine".
Starting the Engine
Engine exhaust contains products of combustion
which may be harmful to your health. Always
start and operate the engine in a well ventilated
area and, if in an enclosed area, vent the exhaust
to the outside.
Starting the Engine
Refer to the Owners Manual of the OEM for your type
of controls. Use the following procedure to start the
engine.
1. Remove all driven equipment loads in order to
allow the engine to start faster, and to reduce the
draining of the battery.
2. Turn the ignition switch to the ON position.
During the key on, all warning lamps will illuminate
for a few seconds, in order to test the circuits. If
any lamps do not illuminate, check the bulbs and
replace as necessary.
NOTICE
Do not engage the starting motor when flywheel is
turning. Do not start the engine under load.
If the engine fails to start within 30 seconds, release
the starter switch or button and wait two minutes to
allow the starting motor to cool before attempting to
start the engine again.
3. Push the start button or turn the ignition switch to
the START position in order to crank the engine.
Do not push down or hold the throttle down while
the engine is cranked. The system will
automatically provide the correct amount of fuel
that is needed to start the engine.
4. If the engine fails to start within 30 seconds,
release the start button, or the ignition switch. Wait
for 2 minutes in order to allow the starting motor to
cool before attempting to start the engine again.
