摘要

氢具有可再生、低排放和优异的燃烧性能，是一种很有前途的内燃机替代燃料。在本研究中，研究了氢气富集对使用优质汽油-乙醇混合物的火花点火发动机热力学分析的影响。分别在优质汽油中添加乙醇（体积比为10%和20%），并在燃烧时注入氢气2、3、4和5 μs。测试是在1500、2000、2500、3000和3500转的不同转速下进行的。能源和火用分析，熵产和可持续性指数评估了不同的燃料混合物，并与优质汽油进行了对比。在所有测试的混合燃料中，在2500 rpm发动机转速下，制动热效率和火用效率最高。在2500转时，E10H5混合燃料的BTE比优质汽油高18%，废气能量比优质汽油高12%。在所有测试的混合燃料中，E10H5混合燃料表现出突出的效果。通过对不同喷射时间下富氢优质汽油-乙醇混合燃料的能量-用能分析，评价其潜在的混合燃料性能。这些混合物将有助于减少对传统化石燃料的依赖，因为它可以在不修改发动机的情况下富集氢。

Energy-exergy and exergoeconomic analysis of a hydrogen-enriched spark-ignition engine fueled with premium gasoline-ethanol blends

Hydrogen is a promising alternative fuel for internal combustion engines due to its renewable nature, low emissions, and superior combustion performance. In the current research, the effects of hydrogen enrichment were studied on the thermodynamic analysis of spark ignition engines using premium gasoline-ethanol blends. The blends were prepared with a partial addition of ethanol (10 % and 20 % by volume) in premium gasoline and hydrogen was injected during combustion for 2, 3, 4, and 5 μs. The testing was done on the varying engine speeds at 1500, 2000, 2500, 3000, and 3500 rpm. Energy and exergy analyses, entropy generation, and sustainability index were assessed for different fuel blends and contrasted with premium gasoline. The brake thermal efficiency and exergy efficiency were found maximum at 2500 rpm engine speed for all tested fuel blends. The BTE of E10H5 fuel blend is 18 % higher than premium gasoline and the exhaust gas energy of the E10H5 fuel blend is 12 % higher than premium gasoline at 2500 rpm. Among all tested fuel blends, the E10H5 fuel blend showed prominent results. The present experimental investigation focuses on energy-exergy analyses of premium gasoline-ethanol blends with enriched hydrogen at different injection times to assess the potential fuel blends. These blends will help to reduce dependency on conventional fossil fuels by enriching hydrogen without modification of the engine.

期刊介绍： The objective of the International Journal of Hydrogen Energy is to facilitate the exchange of new ideas, technological advancements, and research findings in the field of Hydrogen Energy among scientists and engineers worldwide. This journal showcases original research, both analytical and experimental, covering various aspects of Hydrogen Energy. These include production, storage, transmission, utilization, enabling technologies, environmental impact, economic considerations, and global perspectives on hydrogen and its carriers such as NH3, CH4, alcohols, etc. The utilization aspect encompasses various methods such as thermochemical (combustion), photochemical, electrochemical (fuel cells), and nuclear conversion of hydrogen, hydrogen isotopes, and hydrogen carriers into thermal, mechanical, and electrical energies. The applications of these energies can be found in transportation (including aerospace), industrial, commercial, and residential sectors.
