1. Nozzle spray Test.
The ability of the nozzle to correctly atomize the fuel can be checked by performing a nozzle spray test.
Pump the nozzle tester and watch the spray pattern.
• A solid stream or large droplets indicates a faulty nozzle.
• Fuel should be well atomized and in a consistent spray pattern.
Leaking injection nozzles can cause:
1. Hard starting.
2. Excessive smoke.
3. Low power.
4. Engine knocking.
5. Injection pump damage.
6. Internal engine damage.
