SAFETY REQUIREMENTS : HDi DIRECT INJECTION SYSTEM

Engines : 8HX - 8HW - 8HY - 8HV

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 (1350 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 seconds before any intervention.

NOTE : This waiting time is necessary in order to allow the high pressure fuel circuit to return to atmospheric pressure.

116

SAFETY REQUIREMENTS : HDi DIRECT INJECTION SYSTEM

Engines : 8HX - 8HW - 8HY - 8HV

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

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.
