4. Setup

Follow these steps for initial setup of your AUTOOL CT160:

1. Unpacking: Carefully remove all components from the packaging and verify against the included accessories list.
2. Placement: Place the main unit on a stable, level surface in a well-ventilated area.
3. Power Connection: Connect the power cable to the unit and then to a suitable 220V power outlet. Ensure the power switch is in the OFF position before connecting.
4. Fluid Preparation:
   • Cleaning Fluid: Pour professional ultrasonic cleaning fluid into the ultrasonic bath. Ensure the fluid level is sufficient to cover the injector nozzles during cleaning.
   • Test Fluid: Pour professional test fluid into the test fluid reservoir. Use the provided funnel to avoid spills.
5. Injector Installation: Install the appropriate upper inlet connectors and secure the oil separator. Mount the injectors onto the test bench, ensuring they are properly sealed with the provided O-rings and the locking rods.

5. Operating Instructions

The AUTOOL CT160 offers various functions for comprehensive injector maintenance. Ensure the unit is properly set up and fluids are at appropriate levels before beginning any operation.

5.1. Ultrasonic Cleaning

Ultrasonic cleaning uses high-frequency sound waves to agitate the cleaning fluid, effectively removing carbon deposits and impurities from the injectors.

1. Place the injectors into the ultrasonic cleaning bath using the provided bracket. Ensure the nozzles are submerged in the cleaning fluid.
2. Select the "Ultrasonic Cleaning" function on the control panel.
3. Set the desired cleaning time. The unit can heat the cleaning fluid to 45°C for improved cleaning efficiency.
4. Start the cleaning process. The unit will send pulse signals to the injectors during cleaning to facilitate the removal of internal deposits.
5. Once cleaning is complete, remove the injectors and inspect them.

5.2. Injector Testing Functions

The CT160 simulates various engine conditions to test injector performance. Ensure injectors are securely mounted on the test bench and connected to the oil separator.

Figure 6: Control Panel with Function Menu.

Available tests include:

• Idle Test (0-20 ms): Simulates engine idling conditions to test injector status.
• Medium Speed Test (0-7.5 ms): Simulates engine operation at medium speed.
• High Speed Test (0-4 ms): Simulates engine high-speed performance.
• Acceleration Test: Simulates car acceleration conditions.
• Shift Speed Test: Simulates car gear shift conditions.
• Leak Test: Checks the sealing integrity of the fuel injector.
• Idle Spray Test: Observes injector spray performance at idle.
• Medium Speed Spray Test: Observes injector spray performance at medium speed.
• High Speed Spray Test: Observes injector spray performance at high speed.
• Unit Info: Displays product number and manufacturing date.

1. Select the desired test function from the menu.
2. Adjust parameters such as pulse width and injection times as needed using the control panel.
3. Start the test. Observe the spray pattern, uniformity, and leakage in the graduated cylinders.
4. Compare the results with expected values to diagnose injector performance.

6. Maintenance

Proper maintenance ensures the longevity and accurate performance of your AUTOOL CT160.

• Fluid Management: After each use, especially after cleaning, drain the used cleaning and test fluids using the drain valves (refer to Figure 4). Dispose of fluids according to local environmental regulations.
• Cleaning the Unit: Wipe down the exterior of the unit with a soft, damp cloth. Avoid using abrasive cleaners or solvents that could damage the finish or electronic components.
• Injector Adapters and Seals: Regularly inspect injector adapters and seals for wear and tear. Replace them as needed to ensure proper sealing and prevent leaks during operation.
• Storage: When not in use, store the unit in a clean, dry environment, away from direct sunlight and extreme temperatures.
