- Electric test of injector solenoid valves with engin e OFF.
- Injector efficiency test with engine started (cut-out test).
- High pressure sy stem efficiency test with engine started
(rail pressure step test).
The initial conditions are:
- Engine on idle
- I nitial pressure in kPa
Press START; three other pushbuttons will be displayed:
-STOP
-STEPUP
-STEPDOWN
Press on STEP UP making the rail operation pressure rise up
to 160.000 kPa.
Let the engine run in these conditions for 5 minutes and see
if there is an y leakage from the rail and from the pipes.
Then press STEP DOWN in order to bring the pressure back
to the initial level.
Press STO P to finish the test.
During the injector operation inspection, the
VARIATION OF THE FUEL DELIVERY is to be
observed while a cylin der is excluded. (the value
must in crease). If the value remains the same the
injector will be loc ked.
