3. Fuel Injector Testing Process

1. Install Injectors: After cleaning, install the fuel injectors onto the oil rail (18) and secure them using the lock pole (7) and lock nuts (2).
2. Connect Fuel Lines: Connect the blue fuel line from the top oil inlet connector (3) to the oil rail.
3. Add Test Fluid: Pour appropriate test fluid into the main reservoir through the top oil inlet connector (3) using the provided funnel. Ensure the fluid level is within the indicated range on the testing agent liquid level (17).
4. Connect Signal Wires: Reconnect the signal wires (9) to the injectors.
5. Select Test Function: On the operation panel (6), select the desired test function (e.g., Idle Speed Test, Leakage Test, Spray Volume Test).
6. Adjust Pressure: Use the pressure regulating knob (10) to adjust the system pressure as required for the selected test, monitoring the pressure gauge (1).
7. Observe Results: Observe the spray pattern and volume in the glass measuring cylinders (4) during the test. The digital display will show working time and injecting times.
8. Drain Test Fluid: After testing, use the oil drain handle (5) and the testing agent drain valve (16) to recover the test fluid.
