In this paper, 'Pico scope' was used to measure and analyze high voltage waveforms of 'Grade injector' and 'IQA injector' due to defective solenoid injector of CRDI diesel engine, and the following conclusions were obtained. In the case of the injector of 'Grade Injector' and 'IQA Injector', there was no change in the injection timing of the injector while the injector was installed. However, by controlling the operation time, It is judged that the injector control is insufficiently controlled when the number of revolutions of the engine is increased to 2000 rpm and 3000 rpm in the idling state in the idling state because the injector failure is precisely controlled in the idling state, When determining the fault injector, the waveform of the 'Grade injector' and 'IQA injector' can be detected by waveform analysis by comparing the injection control time by measuring the high voltagewaveform of the injector control in idle idling state. Can be easily diagnosed and maintained. I hope this study will be handed to the mechanics to make diagnosis of CRDI injector convenient.
