Hydrogen energy is becoming more and more important in the research of internal combustion engine, so the performance optimization of hydrogen engine injector has become a research hotspot. Based on the drive control technology, this paper put forward an optimization scheme of needle rebound of injector in hydrogen engine to optimize engine performance. The main research methods include: experimental design and testing, drive control circuit design, simulation model establishment and implementation of improvement measures. In the experimental design part, a test platform was built to simulate the actual working conditions, and the test process was controlled and analyzed by using high-precision sensors and data acquisition systems. The main design of the driving control circuit focused on the step-up and step-down chopper circuit, which made the driving of the needle valve controllable. The simulation model was established in Simulink, and different driving waveforms were simulated and analyzed. The improvement measures include small electromagnetic force suppression strategy and driving waveform optimization. Through simulation and experimental data, the effectiveness of the improvement measures in controlling the rebound of needle valve seat was verified. Through simulation and experimental data analysis, it was concluded that the improved small electromagnetic force significantly reduced the rebound height of the needle valve, optimized the driving waveform and shortened the dynamic response time of the needle valve. It also improved the accuracy and repeatability of injection. The experimental data showed that the maximum seating speed of the needle valve reached 4 mm/s, and the maximum rebound height was only 0.4 mm after the electromagnetic force was applied, which verified the effectiveness of the improvement measures in controlling the needle valve seating rebound and provided strong technical support for the design and application of the hydrogen engine injector.
