솔레노이드 인젝터 분사 상태 실시간 모니터링 시스템 설계 Design of the Solenoid Injector Injection Condition Real-time Monitoring System
pp.1340-1343
This study aims to measure the current control waveform of an injector in real time using the developed monitoring system and verify its compliance with the manufacturer’s control waveform requirements. The measured operating waveforms include a peak current phase of 20A and a hold current phase of 10A. The injector of the engine was tested at 1500 RPM and 2000 RPM under conditions of normal fuel injection, small fuel injection, and large fuel injection. In this research, a real-time monitoring system was designed, incorporating an FPGA board and RS232 communication for PC interaction. This system is capable of measuring four channels simultaneously. Furthermore, it is expected that the system could measure up to 12 cylinders concurrently with the addition of more current probes while maintaining the same system configuration. The real-time collection of output waveforms using the developed monitoring system confirmed that the injector operates correctly and meets the manufacturer’s requirements.
