SAFETY REQUIREMENTS: HDi DIRECT INJECTION SYSTEM
Safety requirements.
Preamble.
All interventions on the injection system must be carried out to conform
with the following requirements and regulations:
- Competent health authorities.
- Accident prevention.
- Environmental protection.
WARNING: Repairs must be carried out by specialised personnel
informed of the safety requirements and of the precautions to be
taken.
Safety requirements.
IMPERATIVE: Take into account the very high pressures in the high
pressure fuel circuit (1600 bars), and respect the requirements
below:
- No smoking in proximity to the high pressure circuit when work is being
carried out.
- Avoid working close to flame or sparks.
Engine running:
- Do not work on the high pressure fuel circuit.
- Always stay clear of the trajectory of any possible jet of fuel, which could
cause serious injuries.
- Do not place your hand close to any leak in the high pressure fuel circuit.After the engine has stopped, wait 30 secondsbefore any intervention.
NOTE:This waiting time is necessary in order to allow the high pressure
fuel circuit to return to atmospheric pressure.
Cleanliness requirements.
Preliminary operations.
IMPERATIVE: The technician should wear clean overall.
Before working on the injection system, it may be necessary to
clean the apertures of the following sensitive componen (refer to
corresponding procedures):
- Fuel filter.
- Fuel high pressure pump.
- Fuel high pressure common injection rail.
- Fuel high pressure pipes
- Diesel injector carriers.
IMPERATIVE: After dismantling, immediately block the apertures of
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.

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 Kit 4073-T
[4]Extension: 4251-T
Checks.
IMPERATIVE : Respect the safety and cleanliness requirements specific to high pressure
diesel injection (HDi) engines.
Connect the tool [1]between the booster pump and the fuel filter (white mark 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 on the fuel return pipe.
Connect the tool [3]on tool [1]or on tool [2].
WARNING: Any check of pressure downstream of the fuel filter is prohibited.
NOTE:To check the pressures while the vehicle is being driven, insert the extension [4] between
tool [3]and tools [1]or [2].
