CHECKS: LOW PRESSURE FUEL SUPPLY CIRCUIT
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] = 0.7 ± 0.4 bar.
Abnormal functioning
Fuel supply pressure Fuel return pressure Checks
Between 3and 3.5bar0.7 ± 0.2 bar Check the condition of the diesel filter
More than 3.5bar Less than 0.7barCheck the low pressure regulator incorporated
in the filter
(locked shut): replace.
More than 3.5bar More than 0.7barCheck the fuel return circuit
(pipe pinched or trapped…)
Between 0.8and 1.5bar Less than 0.7barCheck the fuel supply circuit:
- Booster pump (low pressure), piping
Impossible to start the engine:Check: diesel injector return flow
(table below).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).Uncouple the diesel injector return pipe.
Check: Observe:
The flow should be drop by drop Diesel injector functioning correctly
Excessive fuel return Diesel injector locked shutEngines: RHY - RHZ (continued)

IMPERATIVE: Respect the safety and cleanliness requirements.
Vacuum pump.
Connect the tool [1]on the vacuum pump (1).
Start the engine.
Pressure should be 0.8 barat 780 rpm.
Boost pressure regulator electrovalve.
Connect the tool [1]between the electrovalve (2)and the valve (3)of the boost pressure regulator.
Compare readings with the values in the table below.

IMPERATIVE: Respect the safety and cleanliness requirements.
EGR valve.
Connect tool [1] on the capsule take-off (2).
Apply a vacuum of approx. 0,6 barseveral times to activate the rod «a».
In abruptly suppressing the vacuum, the valve should click and lock itself back on its seating.
Regulation electrovalve (EGR).
Check to be performed between the electrovalve (1)and the EGR valve (2).
Link the tool [1]in series, between the electrovalve (1)and the capsule (2).
Compare the values noted with those in the table below.
