Premières étapes :

1. Connecter l'alimentation : Plug the unit into a grounded AC110V power outlet.
2. Installer la vanne de vidange : Attach the cleaning/testing agent discharge valve to the designated port.
3. Prepare Ultrasonic Bath: Place the ultrasonic cleaning assembly into its designated slot.
4. Install Signal Wires: Connect the pulse signal connection cables to the unit.

5. Mode d'emploi

The CNC602A offers both ultrasonic cleaning and various testing functions for fuel injectors.

5.1. Procédure de nettoyage par ultrasons

1. Pre-clean Injectors: Clean the injector's exterior with gasoline or a suitable cleaning liquid before placing them in the unit.
2. Placer les injecteurs : Position the injectors in the ultrasonic bathtub.
3. Ajouter du liquide de nettoyage : 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. Procédure de test des injecteurs de carburant

1. Mount Injectors: Secure the cleaned injectors onto the main machine's test bench.
2. Ajouter le liquide de test : 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. Sélectionner la fonction de test : Use the control panel to select the desired test function (e.g., Idle Speed Test, Leakage Test, Sprayability Test).
5. Ajuster les paramètres : Set simulated RPM, time, and pulse width as required for the selected test.
6. Démarrer le test: Initiate the test and observe injector performance in the graduated cylinders.
7. Régler la pression : Use the pressure adjustment knob to modify system pressure during testing as needed.

Available Testing Functions:

• Nettoyage par ultrasons : Removes carbon deposits and impurities using ultrasonic vibration.
• Test de vitesse au ralenti (0-20 ms) : Simule le régime de ralenti du moteur pour tester l'état des injecteurs.
• Test de vitesse moyenne (0-7.5 ms) : Simulates medium engine speed to test injector state.
• Test haute vitesse (0-4 ms) : Simulates high engine speed to test injector state.
• Test d'accélération : Simulates vehicle acceleration to test injector performance.
• Test de vitesse de changement de vitesse : Simulates vehicle shifting state to test injector working performance.
• Test de fuite: Vérifie l'étanchéité de l'injecteur de carburant.
• Test de pulvérisation au ralenti : Tests spray performance at engine idling state.
• Test de pulvérisation à vitesse moyenne : Tests spray performance at medium engine speed.
• Test de pulvérisation à haute vitesse : Tests spray performance at high engine speed.
• Chasse d'eau inversée : Cleans injectors by flowing test liquid from outlet to inlet, removing internal dirt or strainers (for top fuel supply injectors).
• Nettoyage sans démontage : Nettoyage direct sans démontage des injecteurs (nécessite des adaptateurs spéciaux).
