5.4.6 Injection chamber, clamping nut, O-ring
WARNING - Risk of burning!
The hot surfaces at the injection nozzle can
cause severe hand burns.
¶
Put on protective gloves before removing
the injector from the injection chamber.
During testing, the CRI/CRIN or CRI Piezo squirts the
test oil into the injection chamber. The test oil flows back
out of the injection chamber via the connection cable to
the injected fuel quantity test connection, see fig. 4.

The O-ring in the injector nozzle seat (D7 or D9)
seals the injection chamber during testing. Depend-
ing on the diameter of the nozzle tip (7 mm or 9
mm) of the injector, the corresponding O-ring D7 or
D9 must be inserted in the injection nozzle seats. Do
not use a defective O-ring for the test.
