Checking Injection Nozzle
WARNING:
When using nozzle tester, do not allow fuel sprayed from
nozzle to contact your hand or body, and make sure that your
eyes are properly protected with goggles.
1. Check initial injection pressure by pumping tester handle one
time per second.
Initial injection pressure:
Used Nozzle
12,259 - 12,749 kPa
(122.6 - 127.5 bar, 125 - 130 kg/cm
2
,
1,778 - 1,849 psi)
New Nozzle
12,749 - 13,730 kPa
(127.5 - 137.3 bar, 130 - 140 kg/cm
2
,
1,849 - 1,991 psi)
I
Always check initial injection pressure before installing
new nozzle.
Do not disassemble injection nozzle assembly. Entrust disas-
sembly or adjustment to BOSCH service shop.
2. Check spray pattern by pumping tester handle 4 to 6 times or
more per second.
a.
If main spray angle is within 30 degrees as shown, injec-
tion nozzle is good.
b.
It is still normal even if a thin stream of spray deviates from
the main spray (pattern B).
3. If spray is not correct, clean injection nozzle tip or replace it.
