Fuel Valve Test Rig for troubleshooting of electronic Caterpillar unit injectors

The VPU 900 CAT unit injector test rig for electronic CAT 35xx / 36xx unit fuel injectors is a small fuel valve test rig. The test rig is comprised of two systems:

  • Pneumatic-hydraulic system:
    • Test of nozzle spray pattern
    • Verification of nozzle tightness (nozzle sealing).
  • Pneumatic-electronic systemtly:
    • Test of solenoid coil (resistance test)
    • Test of solenoid activation

The system is simple to use and is a go / no-go test solution.  Should any of the four tests fail, the unit injector should be replaced with a good unit injector.
