Diesel Injector Nozzle Tester (also known as a Diesel Injector Nozzle Pop Tester).
This tool is used in automotive and tractor repair to test and calibrate diesel fuel injectors. Its functions include:
Opening pressure test: Verifying the pressure at which the injector nozzle opens.
Leakage test: Checking for leaks in the injector nozzle and its seat.
Spray pattern and atomization inspection: Assessing the quality of the fuel spray from the nozzle.
Chatter characteristic test: Evaluating the proper functioning and sealing of the injector.
The tester typically features a hand pump to build pressure and a gauge to display the pressure readings, often with dual scales for different units like Bar and PSI.
