INJECTION
SAFETY REQUIREMENTS : HDi DIRECT INJECTION SYSTEM
Engines : RHY - RHZ - 4HX
CLEANLINESS REQUIREMENTS.
Preliminary operations
IMPERATIVE : The technician should wear clean overalls.
Before working on the injection system, it may be necessary to clean the apertures of the following sensitive components :
(refer to corresponding procedures).
- Fuel filter.
- High pressure fuel pump.
- Third piston deactivator.
- High pressure regulator.
- High pressure sensor.
- High pressure fuel injection common rail.
- High pressure fuel pipes
- Diesel injector carriers.
IMPERATIVE : After dismantling, immediately block the apertures of the sensitive components with plugs, to avoid the entry of impurities.
Work area.
- The work area must be clean and free of clutter.
- Components being worked on must be protected from dust contamination.

TOOLS
[1] Ø 10 mmlow pressure connector: 4215-T.
[2] Ø 8 mmlow pressure connector: 4218 -T.
[3] Pressure gauge for testing boost pressure : 4073-T Tool kit 4073-T
[4] Extension: 4251-T.
Connect the tool[1]Between the booster pump and the fuel filter (white mark at "a" on the
fuel supply pipe).
Connect the tool[2]downstream of the diesel injectors, Between the high pressure fuel
pump and the fuel filter(green mark at "b" on the fuel return pipe).
WARNING : Any check of pressure downstream of the fuel filter is PROHIBITED.
NOTE : To check the pressures while the vehicle is being driven, insert tool[4] Between
tool[3] and tools[1] et[2].
Checks on pressure : static.
- Switch on ignition
- For 3 seconds(normal functioning):
- Fuel supply pressure shown by the pressure gauge [3] = 2.6 ± 0.4 Bar.
- Fuel return pressure shown by the pressure gauge [3] = 0.6 ± 0.4 Bar.

CHECKS : LOW PRESSURE FUEL SUPPLY CIRCUIT
Engines : RHY - RHZ - 4HX (continued)
Checks on pressure : dynamic.
Engine running, at idle (normal functioning):
- Fuel supply pressure shown by the pressure gauge [3] = 2 ± 0.4 Bar.
- Fuel return pressure shown by the pressure gauge [3] = 0.8 ± 0.4 Bar.
Abnormal functioning
Impossible to start the engine :
Fuel supply pressure less than 0.8 Bar:
- Check the low pressure regulator incorporated in the filter(locked open)
- Check the high pressure pump distribution valve (locked shut)Check : diesel injector return flow. (Table below)
Uncouple the diesel injector return pipe.

Between 3.3et 4 Bars 0.8 ± 0.4 BarCheck the condition of the diesel filter
More than 4 Bars
More than 4 BarsLess than 0.8 Bar
More than 0.8 BarCheck the low pressure regulator incorporated in
the filter (locked shut) : replace.
Check the fuel return circuit (pipe pinched or trapped...).
Between 0.8et 1.5 BarLess than 0.8 BarCheck the fuel suppy circuit :
- Booster pump(low pressure), piping.
Check :
Observe :
The flow should be drop by drop
Diesel injector functioning correctly
Excessive fuel return
Diesel injector locked shut.
