ANCEL ANJ400 Fuel Injector Tester & Cleaner is a professional 4 cylinders auto fuel injector testing cleaning machine. It is equipped with a pressure gauge which can make the test more precise and easier.Perfectly suit for removing carbon from gasoline cars and motorcycles fuel system, testing leaking, cleaning spark plug, testing injection of injector.
 
Function Explanation:
🏆1.Ultrasonic Cleaning
Ultrasonic cleaning is to use the penetrating and cavitation shock waves generated when ultrasonic waves propagate in the medium, and powerfully clean objects with complex shapes, cavities and pores to completely remove stubborn carbon deposits on the fuel injector.
🏆2.Fuel Injector Cleaning & Tester
This function is to detect the atomization, dripping, blockage, fuel injection angle status of the fuel injectors and the size and balance of the fuel injection of each fuel injector at different speeds.
 
Main functions:
Ultrasonic cleaning:
To clean injectors to remove the carbon deposition on them completely.
Resistance test:
To test the resistance of fuel injector
Leakage test:
To test the sealing and dribbling conditions of injectors under system pressure.
On-Vehicle Cleaning:
Coming with a variety of disassembly-free cleaning connectors, the device can be used to perform on-vehicle cleaning and maintenance for various vehicle models.
Injecting Flow Test:
To check the injecting amount of the injector in 15 seconds of constant injection.
Uniformity / Sprayability test:
To test the uniformity of injecting amount of each injector, and to monitor the spraying status of each injector with the help of backlight.
Reverse Cleaning
 
Working mode:
Mode 1 Accelerated Test
Mode 2 Deceleration Test
Mode 3 Accelerated Test + Deceleration Test
 
Main Features:
The special structure design makes the disassembly and assembly of the fuel separator easier and greatly improves the work efficiency.
With the resistance test of the injectors one by one, get to know the condition of the injectors
The ultrasonic cleaner is integrated on the machine, which makes the operation easier and more efficient.
With the dedicated motherboard, it can support the full and long test of low resistant fuel injector such as 1 ohm.
The unique fuel circuit depressurization technology can make the machine automatically depressurize in the case of sudden shutdown, avoiding equipment damage or personal injury.
The brightness of the screen and backlight, and the level of the buzzer can be manually set and saved.
The product adopts fuel pressure adjustment and control technology by microcomputer, which can ensure stable fuel pressure and wide adjustable range. It is applicable to vehicles equipped with a variety of gasoline injection
systems. Meanwhile, the automation of injectors’ cleaning and testing processes can be realized.
Thanks to the adoption of microcomputer automatic control and digital display technologies, the cleaning and testing processes can be controlled automatically, and the parameters of the main status can be monitored in real time.
Adopting humanization design can make the system pressure fast restored to the default values.

ANCEL ANJ400 Operation Process:

1. Clean injector's outside with gasoline or cleaning liquid before turning on the machine 
2. Putting injectors in ultrasonic bathtub after the outside of injector is free of dirt. 
3. Turn on ultrasonic system, allowing the ultrasonic energy to dislodge any particles even build-up inside the injectors. 
4. Fix injectors on the machine 
5. Test injectors for resistance, shorts, and current draw 
6. Perform leak test, spray pattern, and flow rate testing on flow bench. 
7. The injectors are now returned to the flow bench for retesting of all functions.

Cleaning & testing sequences 
Recommended to carry out the complete cleaning and testing procedures as the following order. 
1. Ultrasonic cleaning; 
2. Uniformity / Sprayability test; 
3. Leakage test; 
4. Injecting flow test; 
5. Working modes test. 

Procedure after work operation 
1) Drain test solution to a fuel container. 
2) Switch off the power switch and unplug the power plug. 
3) Use a fuel header to suck all cleaning agent in the ultrasonic cleaning pool, and wipe the pool with a soft dry 
cloth. 
4) Wipe the table top of the machine with a soft dry cloth.
5) To avoid volatilization, all the test solution in the fuel tank should be discharged. If it can be used again, store it 
in a safe place. If it is dirty and cannot be used any more, dispose it according to relevant regulations.
