燃油噴射泵的圖庫。
Two low-pressure relief valves (A1) are fitted on the
body of the fuel
injection pump. They keep a constant
pressure of 90 to 117 kN/m (13 to 17
lbf/in ) in the
fuel supply to the gallery of the pump and allow the
surplus fuel to return to the fuel tank. Fuel enters the
elements of the
fuel injection pump and is sent at high
pressure, by the elements, to the 12
’low s pring’ type
of fuel injectors. The fuel injectors are set to operate
at 243 bar (240 atmospheres).
Early engines are fitted with Bosch or
OMAP fuel
injectors. New engines are fitted with composite
rocker
covers and these have Stanadyne fuel
injectors, as shown (B).
These fuel
injectors are longer than the other types to
allow the leak-off banjo
connections to be fitted
directly to the bodies of the fuel injec tors above
the
composite rocker covers. Other details are generally
similar to the
Bosch and the OMAP fuel injectors.
From the leak-off banjo connections a
system of pipes
directs the leak-off fuel to a connection block where it
mixes with the spill fuel and the surplus fuel from the
fuel injection
pump. It is then returned to the fuel tank.
The connection block has a vent
plug for the low-
pressure fuel system. For new engines the
connection
block is part of the fuel filter head.
Clean thoroughly each component, and
the area
around it, before it is dismantled or removed.
Fit suitable caps
and plugs to all of the unions
immediately after they have been dis
connected.
Components must be absolutely clean and kept
safely until
they are used during the maintenance or
the overhaul of the fuel system.
如何清洗帕金斯柴油初級(jí)燃油濾清器
Primary fuel filter
How to clean the primary fuel filter
1 Remove the
three bolts (A1) and remove the filter
bowl (A2).
2 Clean all of the
components with paraffin and dry
them with a compressed air jet.
3 Fit
the bowl to the filter head, together with a new
sealing ring. Align the
clamp ring (A3) and fasten it
with the three bolts.
Early engines can be
fitted with filters which have
elements that can be cleaned. These
elements
should be removed, cleaned with fuel oil and dried
with a
compressed air jet.
Fuel filter canisters
How to renew the canisters
of
the main fuel filter
On new engines the main fuel filter is fitted at the
rear
of the engine on the ‘A’ bank side. For early engines
it is fitted
to the 'B' bank side, against the cover of the
coolant gallery as shown
(B). The filter has two
disposable canisters. Both canisters must be
renewed at the same time.
1 Clean the area around the filter and remove
the fuel
filter canis ters. If neces sary, use a strap wrench.
Discard
the canisters.
2 Check that the sealing ring (B1) is fitted correctly to
each new canister and clean the contact faces of the
filter head.
3
Lubricate the top of the canister seal (B1) with clean
fuel oil and renew
the sealing ring (B2) on the adaptor.
4 Fit the new canisters to their
threaded adaptors and
tighten each canister until the sealing ring just
comes
into contact with the filter head. Continue to tighten
overtighten.
After the fuel filter canisters have been renewed,
eliminate air from the low pressure fuel system as
given in operation
20-16.
Fuel filter head
The fuel filter head is fitted at the rear of the engine
on the ’A’ bank side. For early engines the fuel filter
head is fitted to the ’B’ bank side, against the cover of
the coolant gallery.
To remove
1 Remov e the two fuel filter canisters.
Caution: Do NOT bend any of the fuel pipes.
2 Disconnect the fuel leak-off pipes from the fuel filter
head. Remove the pipes if relevant to the job.
3 Disconnect the three low pres sure fuel pipes from
the fuel filter head. Remove the pipes if relevant to
the job.
4 Hold the fuel filter head and remove the two bolts
and nuts. Withdraw the bolts and collect the spacers
and washers.
To fit
1 Fit the fuel filter head to the air filter bracket and
retain it with the two bolts and nuts complete with
spacers and plain and spring washers. The spacers
must be fitted between the fuel filter head and the air
filter bracket. Tighten the nuts to a torque of 23 Nm
(17 lbf ft).
2 Fit the three low pressure fuel pipes. Use new
copper sealing washers.
3 Fit the fuel leak-off pipes. Use new copper sealing
washers.
4 Fit the two fuel filter canisters, see operation 20-2.
5 Eliminate air from the low pressure fuel system as
given in operation 20-16.
