Step-by-step injector service workflow
Step-by-Step Workflow
Use CT450 to clean and test ordinary and GDI-family injectors by selecting the correct adapter, voltage, fluid, temperature, pressure, and function.
01
Step 01
Identify Injector And Select Adapter
Confirm whether the injector is ordinary, GDI, EFI, or FSI, then select the correct connector, adapter, and 12V / 70V / 120V voltage.
02
Step 02
Add Cleaning Fluid And Set Heating
Fill the 2000 mL tank with professional cleaning fluid before starting ultrasonic cleaning, then set automatic heating up to 50°C as required.
03
Step 03
Run Heated Ultrasonic Injector Cleaning
Use the 28 kHz ultrasonic system and pulse connection to clean deposits from the injectors.
04
Step 04
Mount Injectors And Plug Unused Positions
Install up to six injectors securely. When testing one injector, plug the other five positions.
05
Step 05
Add Test Fluid And Configure The Test
Add professional injector test fluid or the stated high-concentration medical alcohol, then set voltage, pressure, time, pulse, and the required function.
06
Step 06
Run Testing Functions
Run the selected simulated-condition, leak, spray-pattern, and pulse-injection tests using the same settings for each injector.
07
Step 07
Reverse Flush, Compare, And Drain
Use reverse flushing only for compatible top-feed injectors. Cleaning without injector removal requires the specified optional adapters. Compare results under identical settings, then drain or recover each fluid as instructed.
Result interpretation
How To Read Test Results
Interpret CT450 results only after the correct injector adapter, drive voltage, test fluid, cleaning temperature, pressure, pulse, time, and test mode have been selected. Follow the table in sequence so every observation leads to a clear adjustment, cleaning, retest, diagnosis, or replacement action.
| 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 |
Important: Keep voltage, pressure, temperature, pulse, time, fluid, and mode identical when comparing injectors or before-and-after results. Heating up to 50°C supports ultrasonic cleaning but final condition must be confirmed through spray, flow, leakage, pulse-response, and operating-condition tests. Use the injector specification, service procedure, or CT450 manual for final acceptance limits.
Fluid, compatibility, and operating limits
Safety & Compatibility
