Introduction
The fuel Injectors are electronically controlled and
incorporate a small solenoid valve. The injectors are
supplied with pressurised fuel by the high pressure
fuel injection pump and when energised, the injector
atomizes the fuel into a fine mist so that it can burn
easily by the vehicle’s engine.
The fuel injectors are mounted in the inlet manifold
so that fuel is sprayed directly at the inlet valves. A
fuel supply rail connects all of the fuel injectors to the
fuel supply.
The injector tips are located inside the combustion
chambers, so effective cooling is essential. A special
thin walled sleeve is screwed into the cylinder head
which allows a coolant jacket close to the injector.
The coolant jacket is sealed at the bottom by sealant
on the sleeve thread and at the top by O-ring.

The injectors can be tested using Servicemaster
diagnostics and by means of a leak off test. To test
for a defective injector first use Servicemaster to
diagnose the problems with the high pressure fuel
injection equipment, specifically when the engine
does not start.
Leak Off Test
The leak off test kit must be installed on the engine
and the ServiceMaster must be used to test the
engine.
1. Operate the engine until it reaches its normal
operating temperature.
2. Stop the engine. Remove the bleed off pipe at
each injector. Refer to (PIL 18-96). Cap the open
connectors on the pipes with the caps in the
injector leak off test kit.

3. Connect the test pipes to the leak off ports on the
four injectors.
4. Position the four plastic bottles as upright as
possible. Keep the test equipment clear of
components that get hot when the engine is
operated.
5. Connect a test pipe to the leak off ports on the
High Pressure valve outlet. Cap the open pipe.
6. Make sure it is safe to start the engine.
7. Use ServiceMaster to control the tests. Refer to
Fuel Injection - Check Operation (PIL 18-18).
7.1. Fuel System Diagnostic Test (Cranking
Only).
7.2. Fuel System Diagnostic Tests (Engine
Running).
8. Examine the fuel levels in the test bottles. If the
difference between any of the levels is more than
10 ml. this indicates that there are one or more
defective injectors.
9. Remove the test equipment and replace the
bleed off pipes. Refer to (PIL 18-96).

Introduction
The fuel rail also known as a common rail, is a
pipe resembling a rail that is used to deliver fuel
to individual fuel injectors on internal combustion
engines. It is designed to have an outlet for each
injector, an inlet for a fuel supply and an outlet for a
fuel bleed off.
The fuel rail also incorporates an attached fuel
pressure sensor and a fuel valve. DO NOT
remove the high pressure fuel valve or the fuel
pressure sensor from the rail. If these components
are defective replace the complete common rail
assembly.

Before Removal
1. Obey all fuel system health and safety
information. Refer to (PIL 18-00).
2. Make sure that the engine is safe to work on. The
engine must cool and pressure in the fuel system
must decay before you start work. If the engine
has been running, wait at least one hour before
you start work.
3. Clean the engine. Refer to Engine-Clean (PIL
15-00).
4. Remove the high pressure fuel pipes. Refer to
Fuel Pipes (high pressure) - Remove and Install
(PIL 18-96).
5. Remove the fuel bleed off pipe at the rail. Refer to
Fuel Pipes (low pressure) - Remove and Install
(PIL 18-96).
Remove
1. Disconnect the electrical connector at the high
pressure fuel valve.
2. Disconnect the electrical connector at the fuel
pressure sensor.
3. Remove the bolts and lift off the common rail
assembly.
Seal the common rail assembly inside a clean plastic
bag until it is ready for use. If the assembly is
defective discard it and get a new one.
Install
1. The installation procedure is the opposite of the
removal procedure. Additionally do the following
steps.
2. Tighten the bolts to the correct torque value.
When renewing the rail assembly make sure to
replace all of the high pressure fuel pipes. Refer to
(PIL 18-96).

Operation
The high pressure fuel injection pump is driven via a
gear on the engine and rotates at half engine speed.
The pump comprises of two sections, the transfer
pump and the high pressure pump.
Although the pump does not control fuel injection
timing, it is still timed in relation to engine phasing.
By timing the pump pressure pulses, the load on the
engine timing gears is reduced together with reduced
mechanical noise.
Transfer Pump Operation
The integral transfer pump is a vane type. An
engine driven rotor houses four vanes in slots.
The rotor rotates inside an eccentric liner. The
vanes are held in contact with the liner by springs.
Fuel is drawn into the pump chamber at port X,
pressurised by the decreasing volume inside the
chamber and expelled at port Y. Fuel pressure
generated by the transfer pump is limited to a
specified pressure by an integral pressure regulating
valve. This pressure is maintained regardless of
engine speed.6bar (87.0psi)

High Pressure Pump Operation
Fuel passes to the high pressure pump via the IMV
(Inlet Metering Valve). The ECM (Engine Control
12. 18 - Fuel and Exhaust System
18 - Injection
15 - Pump
18 - 71 9813/7600-3 18 - 71
Module) controlled IMV determines the amount of
fuel transferred to the high pressure pump. The
plunger actuator block is located on the engine driven
eccentric shaft. When the shaft rotates the actuator
block operates the two plungers. As one plunger is
pushed up its chamber the other is pushed down by
its spring.
State 1 - Charging
Note: The description is for one plunger. The
opposite plunger operates in an identical way. The
inlet and delivery ports from each plunger are
connected by internal galleries.
When the eccentric shaft is in the position shown
force from spring moves the plunger down its
chamber. Pressure in the chamber falls below the
rail pressure and the delivery valve closes. Transfer
pressure is now sufficient to force inlet valve off its
seat and allow the fuel to fill the chamber.

State 2 - Pumping
Note: The description is for one plunger. The
opposite plunger operates in an identical way. The
inlet and delivery ports from each plunger are
connected by internal galleries.
When the eccentric shaft is in the position shown the
actuator block moves the plunger up its chamber.
Fuel pressure in the chamber rises and forces the
inlet valve on to its seat. As the plunger is pushed
further up its chamber the fuel pressure exceeds that
of the rail pressure and the delivery valve is forced off
its seat. Fuel is forced into the rail at high pressure.

18 - 77 9813/7600-3 18 - 77
Operation
In certain operating conditions, the HPV (High
Pressure Valve) controls the fuel pressure inside the
common rail.
When the valve opens, fuel is bled from the rail back
to the fuel tank, reducing the fuel pressure inside the
fuel rail. The valve is actuated by a solenoid coil and
features proportional control. The fuel flow through
the valve is proportional to the current supplied to
the coil. The current value is controlled by the ECM
(Engine Control Module) using PWM (Pulse Width
Modulation).
During normal engine operation, the fuel pressure is
controlled solely by the IMV (Inlet Metering Valve),
refer to (PIL 18-18).
In some operating circumstances, the IMV is unable
to alter the fuel pressure in the common rail quickly
enough. At these times, the ECM activates the HPV.
Typically the valve is used in the following conditions:
• Extreme transients, for example if the operator
goes from full throttle to no throttle quickly.
• When the fuel is cold.
In the event of an IMV failure, the ECM compensates
by altering the control of the HPV to ensure the
engine performance is sufficient to limp home.
Check (Operation)
For the full inspection and testing procedure, refer to
the help files in ServiceMaster.
