ENGINE MECHANICAL - Troubleshooting (Diesel Engine Diagnosis)

5. IMPROPER OPERATION OF

INJECTION NOZZLES OR
DELIVERY VALVES

With engine idling, loosen injection pipe to each
cylinder in order, and check if idle speed changes.

If no change, a faulty cylinder is indicated.
Check according to following procedure.

• Faulty injection nozzle

Check injection nozzle with a nozzle tester.

(See page FU-10 or 20)

Opening pressure:

I P Z a n d i H Z 135-155 kg/cm

(1,920-2,205 psi)
(13,239-15,200 kPa)

1HD-T

No.1 opening pressure

180-190 kg/cm

(2,560-2,702 psi)
(17,652 - 18,633 kPa)

No.2 opening pressure
(Inspection pressure)

132-138 kg/cm

(1,877-1,963 psi)
(12,945-13,533 kPa)

If not as above, nozzle adjustment is improper and
pressure should be readjusted.

If pressure cannot be adjusted to specification, re-
place injection nozzle.

• Faulty delivery valve

If injection pressure is as specified, delivery vale is

defective and should be replaced.
