This paper investigates the waveform analysis of voltage and current waveform from CRDI engine. It is on developing on analysis method of waveform CRDI Diesel engine. The experimental methods using Pico oscilloscope are employed to measure current and voltage waveform of solenoid injector from CRDI engine. The one normal and two abnormal solenoid injectors are used. The experiment is carried out during no-load condition. A summary of the important results are as follows.
1) The area of the voltage and current waveform of the abnormal injector becomes larger than the that of normal injector.
2) The area of the current waveform can be obtained more accurate results than that of voltage waveform.
