5.4.9 Hose assemblies
!
When positioning the hose assemblies, e.g. on the
work surface, always ensure that the area is clean.
Every time before connecting the hose assembly to
the CRI/CRIN or piezo CRI, always make sure the
hose connections are clean.
i
All hose assemblies have a preinstalled strainer.
They collect contaminants which may appear during
testing despite cleaning the CRI/CRIN or piezo CRI.
They are used in the hose assemblies for the test
oil return and the hose assembly for the injection
chamber.
!
Change the strainer in regular intervals (see main-
tenance intervals in chapter 8.2.1). If the strainer is
not changed in time, it might break under increasing
dynamic pressure. Any dirt building up will no longer
be stopped from entering the system and damaging
components.
Hose assembly 1 684 462 570 and hose fitting
The hose assembly 1 684 462 570 (Fig. 9, item 1)
connect the injector return to the test connection for
the return quantity (see Fig. 3, item 3). Different hose
fittings are available for connecting the hose assembly
to different types of injectors (see Fig. 9). These are
inserted into the hose assembly before connecting to
the injector.
For certain CRIN from Bosch, the "CRIN adapter with
check valve" (Fig. 9, item 9) must be used as well. It is
inserted into the test connection for the return quantity
(CRI/CRIN, piezo CRI; see Fig. 3, item 3) prior to start-
ing the test and then connected to the hose assembly
1 684 462 570 (Fig. 9, item 1).
i
After the CRIN is selected, whether or not the "CRIN
adapter with check valve" (Fig. 9, item 9) is needed
for the test is displayed in the EPS 118 software.
!
If the "CRIN adapter with check valve"
(Fig. 9, item 9) is not used in accordance with the in-
structions or is connected incorrectly (e. g. directly
to the CRIN), a faulty measurement results, leading
to an incorrect evaluation of the CRIN.
