3.1.3 Filling fuel
a.
The filled diesel fuel should meet the specifications.
b.
Keep the diesel fuel clean, and the diesel fuel should be sedimentated
for 72h or more and then filled into the fuel tank through the built-in
mesh. Check whether the fuel level is proper, whether the valves on the
fuel pipeline are opened and whether the fuel is leaked. Then loosen the
fuel-return screw on the high-pressure pump, and use a manual fuel
supply pump to drain the air. After that, tighten the fuel-return screw.
Continue pumping fuel until the low-pressure chamber in fuel supply
pump has the pressure of 50kPa.
Note: At each time of starting diesel engine, check the diesel fuel level.
3.1.4 Outgassing of fuel system
a.
Loosen the screw at the outlet of fuel supply pump by half circle.
Repeat pressing down the hand pump until the diesel emerges, then
tighten the screw.
b.
Loosen the vent screw on the fuel filter. Repeat pressing down the hand
pump until the diesel emerges, then tighten the vent screw.
c.
Loosen the vent screw on the fuel injection pump. Repeat pressing
down the hand pump until the diesel emerges, then tighten the vent
screw.
d.
Continue to pump the hand pump to check whether the fuel pipe leaks,
then tighten the hand pump.
3.1.5 Filling coolant
Coolant is formulated by the softened clean water, anticorrosive agent and
antifreezing agent, which should strictly follow the regulations from additive
manufacturer. The coolant should be filled via the inlet of radiator and heat
exchanger to drain the air in the cooling system. Check the coolant level in
fresh-water cooler, if needed, refill properly. With diesel engine running at
low speed, observe whether the coolant level in the fresh-water cooler drops.
A few minutes after the engine is switched off, check whether the level
returns to the original height. If not, refill the coolant to the level. As the
coolant may suddenly rush upward, it is accurate that measuring the level
should be conducted conditioned by coolant staying still.
Note: At each time of starting diesel engine, check the coolant level.
