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,设计了喷氢控制算法,并基于Pareto秩和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软硬件设计。实现了随工况变化动态寻优,使氢发动机动力性、经济性与排放等综合性能达到优化的目标。
The injection control algorithm was designed after analysing the influence of hydrogen injection timing and hydrogen injection quantity on the working performance of hydrogen- fueled engine. The software and the hardware of the electronic hydrogen injection control system was designed based on entire automatism demarcating algorithm which is combined by pareto order and partial decision- making . It realizes the goal of optimizing to change with working condition dynamically and optimizing the integrated performance of hydrogen - fueled engine such as power performance, economic performance and exhaust emission performance etc.
