Step-by-step injector service workflow
Step-by-Step Workflow
Use CT150 to clean injector exteriors, perform ultrasonic cleaning, mount injectors on the flow bench, and run leakage, spray-pattern, and flow-rate tests with the correct fluids.
01
Clean exterior
Clean Injector Exterior
Clean the injector exterior with cleaning liquid before operating the machine, then place the injectors in the ultrasonic bath after loose dirt is removed.
- Remove loose dirt before the machine is operated.
- Clean the injector exterior with the correct cleaning liquid.
- Inspect the injector body and electrical connector before immersion.
02
Ultrasonic clean
Run Ultrasonic Injector Cleaning
Add the correct ultrasonic cleaning fluid and start the ultrasonic system. Keep the fluid below the electrical pulse connector. Recover or dispose of the used solution according to the fluid instructions.
- Add the correct ultrasonic cleaning fluid before starting.
- Keep the fluid below the electrical pulse connector.
- Do not run the ultrasonic tank dry.
03
Mount and fill
Mount Injectors and Add Test Fluid
Secure the injectors on the main unit. Check resistance, shorts, and current draw as needed. Then add professional test fluid or industrial alcohol to about half of the glass tube, as directed.
- Secure up to four compatible injectors in fixed positions.
- Check resistance, shorts, and current draw as needed.
- Use professional test fluid or the stated alternative in the test circuit.
04
Test and compare
Run Leakage, Spray, and Flow Tests
Perform leakage, spray-pattern, and flow-rate tests, then repeat the same settings after cleaning to compare performance before and after service.
- Use the same pressure, pulse width, mode, and test time.
- Compare spray pattern and measuring-tube levels side by side.
- Repeat the same settings after cleaning for a matched result.
Result interpretation
How To Read Test Results
Run every comparison with the same injector setup, test fluid, pressure, pulse width, test time, and selected mode. Review each result, then complete the recommended next step before continuing the diagnosis.
| What You Observe | What It May Mean | Recommended Next Step |
|---|---|---|
| Drips while closed | Contamination, valve-seat wear, or a sealing fault | Clean and re-test; refer or replace if leakage remains |
| One measuring cylinder fills much less | Restriction, installation leak, channel issue, or injector fault | Check pressure and sealing, swap channels, then clean and repeat |
| Deflected, split, coarse, or dripping spray | Deposit, nozzle damage, or internal mechanical issue | Clean and re-test; use specialist service if unchanged |
| Difference becomes smaller after cleaning | A recoverable restriction may have been reduced | Record the result, renew applicable seals, and verify on the vehicle |
| No measurable improvement | The injector may already be clean or have electrical / mechanical damage | Stop repeated cleaning and continue diagnosis, specialist testing, or replacement |
| Bench results look balanced but the vehicle still misfires | The root cause may be outside the injector system | Check ignition, compression, intake leakage, fuel pressure, and control signals |
Compare injectors only under identical settings. A single visual difference should be confirmed by repeating the same test. Use the injector specification, vehicle service procedure, or CT150 manual for final acceptance limits and replacement decisions.
Fluid, compatibility, and operating limits
Safety & Compatibility
Read these fluid, compatibility, and operating rules before using CT150. Cleaning fluid and test fluid serve different purposes and must be used in the correct circuit.
Use Proper Cleaning Fluid
For ultrasonic cleaning, use professional fuel injector cleaning fluid formulated for ultrasonic tanks or professional engine carbon cleaning fluid for better carbon-deposit removal.
Use Proper Test Fluid
For injector testing, use professional fuel injector test fluid. If it is not available locally, 75%+ medical alcohol may be used as an alternative.
Do Not Test With Cleaning Liquid
Corrosive cleaning liquid can damage internal components, corrode rubber parts, and cause leakage. Do not use cleaning fluid as injector test fluid.
Add Fluid Before Ultrasonic Cleaning
Add the correct ultrasonic cleaning fluid before running the ultrasonic function. Do not run the tank dry. Keep the fluid below the electrical pulse connector.
Diesel Injectors: Clean Only
CT150 can clean diesel injectors, but it cannot test diesel injectors. Testing is intended for compatible gasoline and supported motorcycle injectors.
Confirm Voltage, Panel, And Accessories
CT150 supports 110V / 220V input. Confirm the required plug and English or Russian panel version. Optional accessories are required for cleaning without injector removal and for some motorcycle applications.
