摘　　要：在分析喷氢正时和喷氢量对氢发动机工作性能影响的基础上,提出了根据发动机运行工况实时调节和修正喷氢参数的优化控制策略,并基于Pareto秩与决策偏好相结合的全自动标定算法,进行了喷氢提前角和喷氢脉宽电控系统的设计。结果表明,随工况变化动态寻优的优化算法,能实现氢发动机动力性、经济性与排放性等综合性能达到优化的目标。The injection control strategy was put forward after analyzing the influence of hydrogen injection timing and hydrogen injection quantity on the working performance of hydrogen-fueled engine. It can adjust and modify the hydrogen injection parameters in real time according to engine＇s operating status and working condition. The design of the electronic hydrogen injection control system was based on automatic calibration algorithm which combined pareto order and partial decision-making. The results indicate that the goal of optimizing the comprehensive performance of hydrogen-fueled engine such as power performance,economic performance,and emission performance can be achieved by optimizing dynamically with working condition.
