This paper is on developing the waveform analysis method in driving control of solenoid injector of CRDI diesel engine. The experimental methods using Pico oscilloscope and scan tool is employed to measure current and voltage waveform of solenoid injector. The solenoid injector are used 1 normal and 2 abnormal injectors. The experiment is carried out during no-load condition. The magnitude of pressure drop is largest main duration, pre and pilot duration in the order named in case of normal injector, whereas was largest pilot duration, pre and main duration in the order named in case of abnormal injectors.
