4. Operating Instructions

The AUTOOL CT 160 offers both ultrasonic cleaning and various testing functions for fuel injectors.

4.1 Ultrasonic Cleaning

This mode uses ultrasonic waves to thoroughly remove carbon deposits and impurities from injectors.

1. Prepare Injectors: Remove the fuel injectors from the vehicle.
2. Connect Injectors: Attach the pulse signal cables to the injectors and place them onto the ultrasonic cleaning bracket within the bath.
3. Add Cleaning Fluid: Pour specialized ultrasonic cleaning fluid into the bath, ensuring the injector nozzles are submerged.
4. Activate Cleaning: Turn on the unit's power switch. On the control panel, select the 'Ultrasonic Cleaning' function (usually Function 01).
5. Start Cleaning: Press the 'Start' button to begin the ultrasonic cleaning process. The unit will emit high-frequency vibrations.
6. Heat Cleaning Fluid (Optional): For enhanced cleaning, activate the 'Heating Switch' to warm the cleaning fluid to approximately 45°C.
7. Duration: Allow the cleaning cycle to complete (typically 10-15 minutes, adjustable).
8. Drain Fluid: After cleaning, open the cleaning agent drain valve to empty the used fluid into a suitable container.

4.2 Fuel Injector Testing

The unit simulates various engine conditions to test injector performance.

1. Install Injectors: Mount the cleaned injectors onto the oil separator rail, ensuring proper sealing with the provided gaskets. Secure them with the locking rods and nuts.
2. Connect Pulse Cables: Connect the pulse signal cables from the unit to each injector.
3. Add Testing Fluid: Pour specialized testing fluid into the main tank using the funnel. Observe the liquid level through the viewing window.
4. Adjust Pressure: Use the pressure adjustment knob to set the desired test pressure, monitoring the pressure gauge.
5. Select Test Function: On the control panel, choose the desired test function (e.g., Idling Test, Leakage Test, Sprayability Test).
6. Start Test: Press the 'Start' button to initiate the test. Observe the spray pattern, volume, and any leaks in the graduated cylinders.
7. Drain Fluid: After testing, open the testing agent drain valve to empty the fluid.
