CT400 Fuel Injector Cleaner & Tester

In view of the increasing maturity and use of the Gasoline direct injection, AUTOOL has released the CT400 GDI Injector Cleaner and Tester machine in 2021. Gasoline direct injection is a technology that injects fuel directly into the cylinder and mixes it with the intake air. Compared to conventional injectors, the use of GDI can help improve engine efficiency and specific power output as well as reduce exhaust emissions. CT400 not only supports GDI, EFI, FSI and other types of fuel injectors, but also compatible with common standard fuel injectors. The CT400 is available in three voltages to drive the GDI injectors, 12V, 70V and 120V, which basically covers the injectors of the majority vehicle brands in Europe, America and Asia.

Your Best Choice --- GDI Type

AUTOOL CT400 adopts the latest and unique GDI fuel injector drive technology, which can drive 12V, 70V, 120V high pressure fuel injectors. Meanwhile, please don\'t worry if you can\'t judge the voltage type of injector, the CT400 will alarm the mismatch voltage, as the CT400 can intelligently determine the required driving voltage of GDI injector.

It is an expert in Injector solutions, featuring 12 injector-specific functions

  1. Ultrasonic cleaning: It sends signals to the injectors through the pulse signal line, using the cleaning fluid with the ultrasonic vibration so as to completely remove the carbon and impurities inside the injectors.
  2. Idle speed test (0-20ms): Simulate the engine idling speed and test the state of the fuel injector.
  3. Medium speed test (0-7.5ms): simulate the engine running at medium speed and test the state of the fuel injector.
  4. High-speed test (0-4ms): Simulate the high-speed performance of the engine and test the state of the fuel injector.
  5. Acceleration test: Simulate the acceleration state of the car and test the performance of the fuel injector.
  6. Shift speed test: Simulate the shifting state of the car and test the working performance of the fuel injector.
  7. Leakage test: Test the sealing condition of the fuel injector.
  8. Idle dpeed sprayability Test: Simulate the engine idling state and test the spraying performance of the fuel injector.
  9. Medium speed sprayability test: Simulate the engine medium-speed state and test the spraying performance of the fuel injector.
  10. High-speed sprayability test: Simulate the high-speed state of the engine and test the spraying performance of the fuel injector.
  11. Reverse flush: Reverse flush is a way to clean the injectors with the test liquid flowing from the outlet to the inlet of the injector. Reverse flush may remove the dirt inside the injector or the injector Strainer (Only for the top fuel supply injector).
  12. No-disassembly cleaning: Direct cleaning without disassembling the injectors, this function is an additional function, which requires special adapters.

Portable Storage Drawer

The portable storage drawer at the bottom is designed to store various parts for handy use and without leaving a mess on your workbench. Every detail is practical and convenient.

Full inspection of injectors

  • Uniformity test: To test the uniformity of injecting amount of each injector.
  • Sprayability test: To monitor the spraying status of each injector with the help of backlight.
  • Leakage test: To test the sealing and dribbling conditions of injectors under high pressure.
  • Injecting flow test: To check the injecting amount of the injector of specific injection condition(eg. same time and number of times).

AUTOOL CT400 model supports 110V/220V supply voltage, as well as simultaneous cleaning and testing of 6-cylinder injectors; Increase efficiency and save time. You can also optionally test two injectors or four injectors for your different needs.

Intelligent cooling system

The AUTOO CT400 injector cleaner is equipped with a cooling fan and thermal protection with a power of 60w. In case of high temperature during use, the cooling system will start intelligently to avoid damaging the machine due to overheating, thus increasing the service life of the machine.

Test level gauge and Drian valve

It allows you to observe the amount of test fluid directly and clearly. Remove the liquid level gauge to drain out the test liquid, which can recover and reuse the test liquid. The oil drain valve can drain the waste cleaning fluid to the old fluid recovery device after cleaning.

Pressure gauge

It allows you to observe the pressure during test to avoid damage to machine or injectors caused by excessive pressure.

Wide compatibility

Support GDI, EFI, FSI and other types of fuel injectors as well as support ordinary fuel injectors. The device supports 110V/220V power supply voltage.

How to choose test fluid?

The test fluid is used to test and judge whether the performance of the fuel injector is in good condition. It is a colorless and transparent liquid with no irritating odor, non-corrosive, and not easy to emit. Its function is to simulate various working states of the fuel injector as a medium. In order to achieve the best test effect, it is recommended to use professional automotive injector test fluids. If it is not available locally, as an alternative, it\'s recommended that medical alcohol with an alcohol content of more than 75% can be used instead of the test fluid.

How to choose cleaning fluid?

Cleaning fluid is used to clean deposits (such as carbon deposits) on fuel injectors, and it is usually highly corrosive and flammable. In order to achieve the best test effect, it is recommended to use professional injector ultrasonic cleaning fluid. If it is not available locally, it\'s recommended that medical alcohol with an alcohol content of more than 75% can be used instead of the cleaning fluid, but note that the effect may not good enough.

How does the CT400 work?

Ultrasonic Cleaning:

  1. Add the cleaning fluid and put the injectors into the ultrasonic cleaning bath.
  2. Connect the pulse signal lines and select the item 1 Ultrasonic Cleaning function to start.

Ultrasonic cleaning bath size: 150x138x90(mm), power: 60W.

Injector Testing

  1. First add the test fluid, then install the injectors on the fuel distributor, and fix them with bolts.
  2. Different functions can be selected to test to see if any of the injectors are leaking or blocked.
