5.2 INJECTION NOZZLE

WARNING

Check the injection nozzle only after confirming that nobody is near the spray. If the spray from the

nozzle contacts the human body, cells may be destroyed and blood poisoning may result.

(a) Good

(b) Bad

5.2.1 Nozzle Spraying Condition

1. Set the injection nozzle in a nozzle tester and check

the nozzle spraying condition.

2. If the spraying condition is defective, replace the

injection nozzle assembly.

5.2.2 Nozzle Injection Pressure

1. Set the injection nozzle in a nozzle tester.
2. Slowly move the tester handle to measure the pres-

sure at which fuel begins jetting out from the nozzle.

3. If the measurement is not within factory specifica-

tions, replace the adjusting washer (1) in the nozzle

holder.

Fuel Injection

Pressure

1st Stage

Factory

Specification

13.73 to 14.71 MPa

140 to 150 kgt/cm

1991 to 2133 psi

(Reference)

A washer thickness of 0.01 mm (0.0004 in.) will vary the

the nozzle injection pressure by approximately 235 kPa

(2.4kgf/cm

, 34 psi.)
