摘　　要：流体集成系统(integrated vehicle fluids,IVF)中氢氧内燃机起着关键作用,以进气道喷射氢气(port fuel injection-hydrogen,PFI-H 2)喷注策略为研究目标,研究该喷射方式下缸内燃烧特性、输出功率等参数,从多角度分析氢内燃机燃烧性能,建立用于IVF系统氢氧内燃机的PFI-H 2燃烧策略。为此,基于GT-power仿真软件,搭建PFI-H 2一维仿真模型,并通过点火性能数据对仿真模型进行校核。结果表明,一维燃烧性能仿真分析可以得到不同工况下氢氧内燃机输出功率,功率在6~8 kW符合设计要求,有效热效率为29.17%~30.08%,且此区间的排气能量占比变化不大,集中在46%~48%。In the integrated vehicle fluids(IVF)system,hydrogen-oxygen internal combustion engines play a crucial role,with a focus on the port fuel injection-hydrogen(PFI-H 2)strategy into the intake manifold.The research aims to study cylinder combustion characteristics,output power,and other parameters under this injection strategy,analyzing hydrogen internal combustion engine performance from multiple perspectives.In order to establish a PFI-H 2 combustion strategy for hydrogen-oxygen internal combustion engines used in IVF systems,a one-dimensional simulation model for PFI-H 2 was constructed using GT-power simulation software.The simulation model was validated using ignition performance data.The results indicate that the one-dimensional combustion performance simulation can provide output power of hydrogen-oxygen internal combustion engines under different operating conditions.The power ranges from 6 to 8 kW,which meets design requirements.The effective thermal efficiency ranges from 29.17%to 30.08%,and the proportion of exhaust energy in this region has little change,concentrated in 46%~48%.
