Top Reasons to Choose Foxwell JT400 4-cylinder Fuel Injector Cleaner & Tester
● [ 100w Ultrasonic Cleaning ]: Start the machine, and press the key to modle 8. lt can perform ultrasonic cleaning on single or multiple injectors simultaneously, which can eliminate thoroughly blockages on the injector accessories and internal.
● [ Automatic Control/Real-time Monitoring ]: Microcomputer automatic control and digital display technology: the cleaning and detection process can be automatically controlled, and the main status parameters can be monitored in real time
● [ 2000ml Large Capacity of Cleaning Tank ]: Foxwell JT400 Fuel injector Cleaner only weighs 12KG, allowing to carry around. With 2000ML large capacity ultra cleaning tank, all injectors can be cleaned at one time, which save much time and more efficient.
● [ Multi Voltage Selection ]:: Foxwell JT400 Fuel Injector 4-cylinder Cleaner and Tester designs with various types of voltage output (12V, 70V & 120V) to be selected to adapt for different types of injector testing.
● [Various Parts equipped ]:: It is equipped with a variety of injector accessories for different needs.
● [ Environmental Friendly& Widely Use ]: The used cleaning fluid and testing fluid can be easily recovered. Support most of the automobile and motorcycles in the market. Applicable voltage is compatible with 110V or 220V.
● [ 5 Years Warranty ]: For damage caused by non-human factors, Foxwell promises to resend parts for free within 5 years. For any needs, you are warmly welcomed to contact us and we will get back to you ASAP within 24 hours.

Foxwell JT400 Main Functions:
1.Injector Test : Detect solenoid injectors resistance
2. UNIFORMITY TEST: Inspect fuel injection of each injector by observing its uniformity.
3. SPRAYABILITY TEST: Inspect atomization of each injector by observing.
4. LEAKAGE TEST: Inspect the sealing conditions of the injector needle valve under system pressure and to
find out the injector with oil droplet.
5. INJECTION TEST: Inspect injecting volume in 10 seconds meets the design specifications.

🎯 Wide Range of Injector Types
● Traditional Injectors
● GDI Injectors

Ultrasonic Cleaning Operation:
1.Pour in the injector detergent and place the injectors in the ultrasonic cleaner tank.
2.Connect the pulse signal wire and select the ultrasonic cleaning function to start working.
Fuel Injector Testing Operation:
1. Pour in the test liquid,install the fuel injector is to the fuel dstributor and fix main unit body
2. Test if the injector is leaking or blocked under different functions.
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.
