CNC-605A GDI Fuel Injector Cleaner & Tester

Professional Maintenance Solution for GDI Engines

The CNC-605A is a specialized Injector Cleaner & Tester designed to meet the demands of modern automotive engines. It is fully compatible with GDI (Gasoline Direct Injection), EFI (Electronic Fuel Injection), and SFI (Sequential Fuel Injection) systems.

The machine simulates various engine working conditions to clean and test injectors effectively. It integrates advanced ultrasonic technology to remove stubborn carbon deposits and uses a pressurized fuel system to verify the performance of each nozzle.

Core Functions:

1. Ultrasonic Cleaning: Uses 60W ultrasonic power to completely remove carbon deposits from the fuel injector nozzle.

2. Uniformity & Sprayability Test: visually detects the uniformity of the injection quantity and monitors the spray pattern (atomization) with the help of a built-in backlight.

3. Sealing Test: Tests the sealing and leakage of the fuel injection nozzle under system pressure (0.1~10bar) to ensure no drips.

4. Injection Volume Test: Makes the nozzle spray continually for a set time to measure the volume of fuel injected.

5. No Disassembly Needed: For EFI & SFI systems, it supports on-vehicle cleaning without removing the injectors (requires appropriate adapters).

6. Automatic Mode: Runs a preset program to automatically test the injectors through various sequences.
   

Application Scenarios:

• Professional Auto Repair Shops: For diagnosing rough idling, misfires, or poor fuel economy caused by clogged GDI injectors.

• Fuel System Service Centers: Offering specialized carbon cleaning services.

• Vehicle Maintenance: Routine cleaning of injectors to restore engine performance and reduce emissions.

FAQ (Frequently Asked Questions)

Q1: Can the CNC-605A clean GDI injectors?
A: Yes, the CNC-605A is specifically designed to support GDI, EFI, and SFI injectors, providing the higher pressure capabilities needed for GDI testing.

Q2: Does it require disassembling the engine to clean?
A: For ultrasonic cleaning and bench testing, you must remove the injectors. However, for EFI and SFI systems, the machine supports "on-vehicle cleaning" (No disassembly needed) mode using specific adapters to clean the fuel rail and injectors while they are on the car.

Q3: What fluid should I use?
A: You need two types of fluids: Ultrasonic Cleaning Fluid for the ultrasonic bath, and Injector Testing Fluid for the glass tubes (spraying test). Note: Do not use cleaning fluid in the testing tubes as it is corrosive to the pump.

Q4: Is it safe to use?
A: Yes, but caution is required. Since the testing fluid is flammable, no open flames are allowed within 2 meters of the machine during operation.

• GDI Support: Unlike older models, the CNC-605A is specifically engineered to handle high-pressure GDI injectors, making it future-proof for modern workshops.

• Powerful Cleaning: The 60W ultrasonic bath ensures deep cleaning of internal components.

• Adjustable Simulation: Users can adjust RPM (100-9900) and Pulse Width (0.5-25ms) in small steps to simulate precise engine loads.

• High-Pressure Capability: Capable of generating up to 10bar of fuel pressure, which is essential for properly testing the spray pattern of direct injection nozzles.

• Dual Voltage Design: The power supply supports AC110V/220V (50Hz/60Hz), making it suitable for global use.

• Automatic Oil Discharge: Features automatic control for oil draining, keeping the workspace clean.
