Important Tips to Start Volvo Power Generator Engine
by Starlight Generator dieselgeneratortechThis article will guide you to learn how to correctly start Volvo power generator engine. If you are interested, then take some times to read it.
Make it a habit of giving the
engine and engine room a visual check before starting. This will help you to
discover quickly if anything abnormal has happened, or is about to happen. Also
check that instruments and warning displays show normal values after you have
started the engine.
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.
Before
Starting
• Check that
the oil level is between the MIN and MAX marks.
NOTICE! The oil level can be read
both when the engine is stopped (the STOP side of the dipstick) and with the
engine running (the OPERATING side of the dipstick).
For filling refer to Oil level,
checking and topping up.
• Open the
fuel valves.
• Check the
fuel pre-filter; refer to Draining condensate, fuel system page 54.
• Check the
coolant level and that the radiator is not blocked externally. Refer to Coolant
Level, Checking and Topping Up page 58 and Charge Air Cooler, External Cleaning
page 59.
WARNING!
Do not open the coolant filler
cap when the engine is hot, except in emergencies, this could cause serious
personal injury. Steam or hot fluid could spray out.
• Check that
no leakage of oil, fuel or coolant is present.
• Turn the
main switch(es) on.
• Move the
engine speed control to idle, and open the disengageable clutch/gearbox if
installed.
IMPORTANT!
Never break the circuit with the
main switch while the Volvo engine is running, as this may damage the
alternator.
Starting the
Engine
The pre-heating time is adjusted
to suit the engine temperature, and can last for up to 50 seconds both before
and after starting. The starter motor connection time is maximized to 20
seconds. After that, the starter motor circuit is temporarily cut to protect
the starter motor against overheating.
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 70. Synthetic
lubricants are able to handle a wider temperature range than mineralbased
lubricants.
• Pre-heat
the coolant with a separately-installed electric engine heater. In extreme
cases, a dieselfired 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
56.
• 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. 3 Start the engine.
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
If the EMS receives abnormal
signals from the engine, the control unit generates fault codes and alarms, in
the form of lamps and audible warnings. This is done by means of CAN signals to
the instrument. More information about fault codes and fault tracing can be
found in the chapter. Fault Handling.
Maneuvering
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).
• Depress the
STOP-button (5).
Extra Stop
For location of the extra stop,
please refer to Maintenance page 47.
WARNING!
Working with or approaching a
running engine is a safety risk. Watch out for rotating components and hot
surfaces.
After Engine
Shutdown
1 Check the engine and engine
compartment for leaks.
2 Turn off the main switches
before any long stoppage.
3 Carry out maintenance in
accordance with the schedule.
For longer
breaks in operation
During longer breaks in
operation, the genset engine must be warmed up at least once every two weeks. This
prevents corrosion in the engine. If you expect the engine to be unused for two
months or more, it must be conserved. Refer to the chapter Storage page 65.
IMPORTANT!
If there is a risk of freezing,
the coolant in the cooling system must have adequate antifreeze protection.
Refer to the chapter Maintenance page 56. A poorly-charged battery can freeze
and burst; refer to Battery, Charging page 64.
