    Abstract: 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.
