5.1. Ultrasonic Cleaning Procedure

1. Pre-clean Injectors: Clean the injector's exterior with gasoline or a suitable cleaning liquid before placing them in the unit.
2. Place Injectors: Position the injectors in the ultrasonic bathtub.
3. Add Cleaning Fluid: Pour cleaning fluid into the ultrasonic bathtub, ensuring injectors are submerged.
4. Connect Pulse Signals: Attach the pulse signal cables to the injectors.
5. Activate Ultrasonic System: Turn on the ultrasonic system. The pulsed energy, combined with the cleaning fluid, will dislodge carbon and impurities from inside the injectors.
6. Heat Mode (Optional): If desired, activate the heating mode for enhanced cleaning.

5.2. Fuel Injector Testing Procedure

1. Mount Injectors: Secure the cleaned injectors onto the main machine's test bench.
2. Add Test Fluid: Pour the dedicated testing fluid into the fuel tank (4700ml capacity). Ensure the fluid level is within the specified range.
3. Connect Power and Signal: Ensure all injectors are correctly connected for power and pulse signals.
4. Select Test Function: Use the control panel to select the desired test function (e.g., Idle Speed Test, Leakage Test, Sprayability Test).
5. Ajustar parâmetros: Set simulated RPM, time, and pulse width as required for the selected test.
6. Iniciar teste: Initiate the test and observe injector performance in the graduated cylinders.
7. Ajuste a pressão: Use the pressure adjustment knob to modify system pressure during testing as needed.

Available Testing Functions:

• Limpeza ultrassônica: Removes carbon deposits and impurities using ultrasonic vibration.
• Idle Speed Test (0-20ms): Simulates engine idling speed to test injector state.
• Medium Speed Test (0-7.5ms): Simulates medium engine speed to test injector state.
• High-Speed Test (0-4ms): Simulates high engine speed to test injector state.
• Teste de aceleração: Simulates vehicle acceleration to test injector performance.
• Shift Speed Test: Simulates vehicle shifting state to test injector working performance.
• Teste de vazamento: Checks the sealing condition of the fuel injector.
• Idle Speed Sprayability Test: Tests spray performance at engine idling state.
• Medium Speed Sprayability Test: Tests spray performance at medium engine speed.
• High-Speed Sprayability Test: Tests spray performance at high engine speed.
• Reverse Flush: Cleans injectors by flowing test liquid from outlet to inlet, removing internal dirt or strainers (for top fuel supply injectors).
• No-Disassembly Cleaning: Direct cleaning without disassembling injectors (requires special adapters).

6. Manutenção

Regular maintenance ensures the longevity and accuracy of your LAUNCH CNC602A unit.

1. Gestão de fluidos: After each use, drain all cleaning and testing fluids from the unit. Store fluids properly according to their safety data sheets.
2. Unidade limpa: Limpe a parte externa da máquina com um pano macio e seco.amp cloth. Avoid using harsh chemicals that may damage the surface or internal components.
