【摘要】 为缓解全球气候变暖，可考虑在汽车发动机上燃烧零碳氨燃料以减少碳排放。但由于氨（NH₃）的燃点高、最小点火能量高以及燃烧缓慢等劣势，需要借助氢气（H₂）作为助燃剂，帮助改善氨燃料发动机的燃料燃烧过程。针对国内外相关文献进行综述，总结了氨氢双燃料发动机掺混燃烧调控方法的研究进展，并分析了氨催化分解制氢与氨燃料发动机耦合的研究现状，发现采用氨燃料在线重整制氢可以避免采用双燃料供给系统。研究结果表明，氢气助燃能提高氨燃料发动机的燃烧速度，降低NO_x的排放量。对于氨燃料发动机依旧存在的动力性能下降和未燃氨气排放等问题，仍需在今后的研究中探索解决。更多还原

【Abstract】 To alleviate global warming, ammonia is being considered as a zero-carbon fuel for automotive engines to reduce carbon emissions. However, due to the disadvantages of ammonia, such as high autoignition temperature, high minimum ignition energy and low laminar flame speed, it is necessary to use hydrogen as a promoter to improve the combustion performance of the ammonia-fueled engine. The paper provides a comprehensive review of relevant literature, summarizing the research advancements in combustion control methods for ammonia/hydrogen dual-fuel engines. It also analyzes the state of research on the coupling between catalytic decomposition of ammonia for hydrogen production and ammonia engines.It is found that the on-board decomposition of ammonia to produce hydrogen can avoid the use of dual fuel supply systems. The results show that the use of hydrogen as a combustion promoter increases the combustion rate of ammonia engines while reducing the emissions of nitrogen oxides. However, issues such as power performance deterioration and unburned ammonia emissions still exist in ammonia engines. These challenges call for further investigation and resolution in future studies.更多还原
