3.1 Storage of engine
1) Clean the diesel engine.
Before preservation, remove all rust with
proper methods and positions to be
treated with protective agent (such as
lubricating oil pipeline, fuel system and
turbocharger) must be cleaned
thoroughly.
2) Protection procedure
a) Drain off oil completely after
warming up and wash the oil filter. Add
anti-rust oil in the oil pan of the diesel
engine.
b) Drain off the diesel in the fuel
system completely and add the mixture
of 90% diesel and 10% anti-rust oil again
to protect the whole fuel circuit. The
mixture must be thoroughly mixed
before addition.
c) If no cooling emulsion is used in the
diesel engine, after the cooling water is
drained, cooling water emulsion and
anti-rust oil shall be added for protection
of cooling water chamber. Before
preservation, add the emulsion and start
the engine as per starting procedures.
Keep the engine idling for 15~25 min.
d) Remove the cover on the end of the
intake pipe, spray anti-rust oil into the
intake pipe with a pressure nozzle, and
turn the crankshaft manually while
spraying oil to open the valve and make
the anti-rust oil seep into the
combustion chamber. Once the
preservation is completed, do not turn
the crankshaft any more to prevent the
oil film attached to the cylinder wall from
being scraped off.
e) Drain the oil/fluid in the diesel
engine. Drain or pump out the anti-rust
fluid from the engine base. Drain
emulsion from the cooling system. Keep
all drain switches at open positions.
f) Remove the rocker arm cover and
spray anti-rust oil to the valve spring and
rocker arm.
g) All machined parts and parts liable
to rust of the diesel engine shall be
applied with preservative oil.
h) The intake and exhaust pipe
(silencer) openings are wrapped with
plastic cloth to prevent foreign matters
and moisture.
With all procedures above done, the
engine is under preservation.
3) Protection measures during storage
To avoid moisture and foreign matters
entering in the diesel engine, during
transportation and storage, the open
ports of intake, exhaust, cooling water
pipes and other parts of the engine shall
be covered up and the diesel engine
shall be coated by plastic shield.
3.2. Storage of alternator
If the alternator is not being used for a
long time, moisture will enter the coil
and cause corrosion. To minimize
moisture condensation, the alternator
shall be placed in a dry place. If possible,
a moisture eliminator shall be used to
keep the coil dry. When the generator
set is moved from the storage place to
the installation place, check its
insulation degree first. If the reading is
lower than that before storage, dry the
coil.
3.3. Storage of control panel
There are precision instruments and
components in the control panel; thus, it
shall be placed in an environment with
ambient temperature of 20 ℃ ~25 ℃ ,
relative humidity of 20%~70% and air
pressure of 70 kPa~106 kPa.
3.4. Storage of battery
Care shall be taken for battery storage: It
shall be kept in a dry, clean and well-
