Ultrasonic Injector Cleaning
The ultrasonic cleaning function effectively removes carbon deposits and blockages from injectors.

Image: Multiple fuel injectors submerged in the ultrasonic cleaning bath, connected by red wires, indicating the ultrasonic cleaning process.
- Place the injectors into the ultrasonic cleaning bath.
- Ensure the cleaning liquid covers the injector nozzles.
- Select the "Ultrasonic Cleaning" function from the control panel.
- Set the desired cleaning time (adjustable from 0-10 minutes).
- Press "START" to begin the cleaning process.
- For reverse flushing, install the injectors in the opposite direction after initial cleaning and repeat the process.
- નોંધ: Only 12V injectors are supported for ultrasonic cleaning. 70V and 120V injectors are not supported for this specific function.
Injector Testing Modes
The CT400 offers 10 testing modes to simulate various driving conditions and diagnose injector performance, including uniformity, atomization, sealing, and injection angle.

Available test modes:
- Idle Test (0-20 ms): Simulates engine idling conditions.
- Medium-Speed Test (0-7.5 ms): Simulates moderate engine speeds.
- High-Speed Test (0-4 ms): Simulates high engine speeds.
- પ્રવેગક પરીક્ષણ: Simulates rapid acceleration.
- શિફ્ટિંગ સ્પીડ ટેસ્ટ: Simulates gear changes.
- લીક ચેકિંગ ટેસ્ટ: Checks for fuel leaks from the injectors.
- નિષ્ક્રિય સ્પ્રે મૂલ્ય પરીક્ષણ: Evaluates spray pattern and volume at idle.
- મધ્યમ ગતિ સ્પ્રે મૂલ્ય પરીક્ષણ: Evaluates spray pattern and volume at medium speed.
- હાઇ સ્પીડ સ્પ્રે મૂલ્ય પરીક્ષણ: Evaluates spray pattern and volume at high speed.
- No-Disassembly Cleaning: Requires connection to C100 special parts for cleaning the combustion chamber or throttle (external accessory).
પરીક્ષણ કરવા માટે:
- Select the desired test mode from the "FUNCTIONS MENU" on the control panel.
