摘要
为探索氢燃料应用于内燃机及车辆的各项性能,在一款2.0 L汽油机的基础上,重新设计发动机各系统及部件,研制出氢内燃机和样车,并进行了台架和整车试验.试验结果显示:氢内燃机功率和扭矩比同排量汽油机均下降40%左右,但最高指示热效率和有效热效率分别可达到40.4%和35.0%,NOx排放主要受混合气当量燃空比的影响.氢内燃机及整车各系统工作正常,动力性能也满足开发要求.氢内燃机汽车CO和HC排放显著降低,NOx排放仅为0.057 g/km,比国Ⅳ标准低了28.75%,具有良好的排放性能.
To explore the performances of hydrogen internal combustion engine （H2ICE） and vehicle, based on the modification of a 2.0 L gasoline engine, H2ICE and vehicle have been successfully developed. Bench and vehicle testing were carried out. Test results show that, while power and torque outputs are 40% lower than gasoline engine, the indicated and brake thermal efficiency of H2ICE could reach 40.4% and 35%, respectively. The H2ICE vehicle has a good emission performance. NO, emission is mainly affected by the fuel-air equivalence ratio of mixed gas. Tested NO, emission is only 0. 057 g/km, compared to the level of national IV standard, which is decreased by 28.75%. CO and HC emissions of H2ICE vehicle are also significantly decreased. The system of H2ICE and vehicle work normally and the dynamic properties meet the development requirements.
