Before
Starting - Volvo Penta Power Generation Engine
• Check that the oil level is
between the MIN and MAX marks. Refer to the “Maintenance, lubrication system”
chapter.
• Open the fuel taps.
• Check that no oil, fuel or
coolant leaks are present.
• Check the air filter pressure
drop indicator. Refer to the “Maintenance, Engine, general” chapter:
• Check the coolant level and that
the radiator is not clogged externally. Refer to the “Maintenance, cooling
system” chapter:
WARNING!
Do not open
the expansion tank cap when the engine is hot. Steam or hot fluid may spray
out.
• Switch on the main electrical
power.
IMPORTANT!
Never
disconnect power with the main switch(es) when the engine is running. This can
damage the alternator.
• Set the engine speed control to
idle, and disengage the clutch/gearbox.
Starting the
Engine
The engine
control lever must always be in neutral before starting. The EDC 4 system makes
sure the engine receives the correct amount of fuel even during cold starts.
Start the
engine.
Adapt the
preheating period to suit engine temperature if the engine is fitted with
preheating.
Starting in
Extreme Cold
Certain
preparations must be made to enable engine starting in extreme cold, and in
some cases to make starting possible at all:
• Use a winter grade fuel (of a
well-known make) that is approved for the prevailing temperature. This reduces
the risk of paraffin wax precipitation in the fuel system. At extremely low
temperatures, we recommend the use of a fuel heater.
•
Use a synthetic engine oil of a viscosity recommended for the prevailing
temperature to achieve satisfactory lubrication. Refer to Viscosity page 58.
Synthetic lubricants are able to handle a wider temperature range than mineral
based lubricants.
• Pre-heat the coolant with a
separately-installed electric engine heater. In extreme cases, a diesel fired
engine heater may be necessary. Ask your Volvo Penta dealer for advice.
• Make sure the cooling system is
filled with a glycol mixture. Refer to Maintenance page 44.
• The batteries must be in good
condition. Cold weather reduces battery capacity. Increased battery capacity
may be necessary.
Never Use
Start Spray
WARNING!
Never use
start spray or similar agents to start an engine. This may cause an explosion
in the inlet manifold. Danger of personal injury.
Starting
Using Auxiliary Batteries
WARNING!
Explosion
hazard. Batteries contain and give off an explosive gas which is highly
flammable and explosive. A short circuit, open flame or spark could cause a
violent explosion. Ventilate well.
1 Check that
the auxiliary batteries are connected (series or parallel) so that the rated
voltage corresponds to the engine system voltage.
2 First
connect the red (+) jumper cable to the auxiliary battery, then to the flat
battery. Then connect the black (-) jumper cable to the auxiliary battery and
to a location that is somewhere away from the discharged battery, e.g. the main
switch negative terminal or the negative terminal on the starter motor.
WARNING!
Do not touch
the connections during the start attempt: Risk of arcing.
Do not bend
over any of the batteries either.
4 Remove the
cables in the reverse order.
IMPORTANT!
The ordinary
cables to the standard batteries must not be loosened under any circumstances.
Operation
Correct
operating technique is very important for both fuel economy and engine life.
Always let the engine warm up to normal operating temperature before operating
at full power. Avoid sudden throttle openings and operation at high engine rpm.
Reading the
Instruments
Check all
instruments directly after starting, and then regularly during operation.
NOTICE! On
engines in continuous operation, the lubrication oil level must be checked at
least every 24 hours. Refer to Oil level, checking and topping up.
Alarms
Fault
indication
If the EDC 4
system receives abnormal signals from the engine the diagnostics lamp will
flash. A fault code for guidance in fault tracing is obtained by pressing the
diagnostics button (alternatively, the fault code can be obtained via CAN).
More
information about fault codes and fault tracing is found in the “Diagnostic
function” chapter.
Effect on
engine
The
diagnostic function affects the engine in the following ways:
1 The
diagnostic function has discovered a minor malfunction which does not damage
the engine. Reaction: The engine is not affected. The diagnostic lamp lights
up.
2 The
diagnosis function has detected a serious malfunction that will not cause the
engine immediate damage (such as high coolant temperature):
Reaction:
The engine goes into emergency (limp home) mode. The diagnostic lamp lights up.
3 The
diagnostic function has discovered a serious malfunction which makes it
impossible to control the engine.
4 Reaction:
The diagnostic lamp flashes. The engine is shut down.
Maneuvering
Speed
control
Avoid
sudden, extreme throttle inputs.
Operation at
low load
Avoid
long-term operation at idle or at low load, since this can lead to increased
oil consumption and eventually to oil leakage from the exhaust manifold, since
oil will seep past the turbocharger seals and accompany the induction air into
the inlet manifold at low turbo pressure.
One
consequence of this is carbon build-up on valves, piston crowns, exhaust ports
and the exhaust turbine.
At low
loads, the combustion temperature may become so low that complete combustion
cannot be ensured, resulting in possible fuel dilution of lubricating oil and
eventually leakage from the exhaust manifold.
If the
following points are done as a complement to normal maintenance, there will be
no risk of malfunctions caused by operation at low load.
• Reduce operation at low load to
a minimum. If the engine is regularly test-run without load once a week, the
duration of this operation should be limited to 5 minutes.
• Run the engine at full load for
about 4 hours once a year. In this way carbon deposits in the engine and
exhaust system are given the chance to burn up.
Engine
Shutdown
During
longer breaks in operation, the engine must be warmed up at least once every
two weeks. This prevents corrosion in the engine. If you expect the engine to
remain unused for two months or more, it must be preserved.
Before
Engine Shutdown
Let the
engine run for a few minutes without any load before stopping it. This allows
engine temperature equalization and prevents boiling once stopped and also
allows the turbochargers to cool down. This contributes to long, fault-free
service life.
Stop the
Engine
• Disengage the clutch (if
possible).
• Depending on the
instrumentation; hold down the stop button until the engine has stopped or turn
the key to the stop position. Release the key once the engine has stopped.
Auxiliary
stop
WARNING!
Working with
or approaching a running engine is a safety risk. Watch out for rotating
components and hot surfaces.
The
auxiliary stop (AUX STOP) is located to the right of the steering unit.
NOTICE! The
auxiliary stop may under no circumstances be used as the "routine"
stop button.
After Engine
Shutdown
• Check the engine and engine bay
for leakage.
• Turn off the main switches
before any long stop page.
• Carry out maintenance in
accordance with the maintenance schedule.
