Studies on the usage of gasoline–alcohol blends as an alternative fuel in spark-ignition engines have recently gained momentum. In the present research, energy, exergy, environmental, enviroeconomic, exergoenvironmental, and exergoenviroeconomic analyses were conducted with the performance and emission values acquired by utilizing gasoline, gasoline–heptanol, and gasoline–hexanol fuels (G100, HEX5-20, and HP5-20) as a fuel under different powers at a constant speed of 1600 rpm in a single-cylinder four-stroke spark-ignition engine. As the ratio of alcohol in fuel blends increases, fuel consumption also increases. NO_X emission is higher, and CO and HC emissions are lower in alcohol-based fuel blends than G100 fuel. The highest thermal efficiency is 41.09% in G100 fuel at a power of 5 kW. As the ratio of alcohol in fuel blends increases, thermal efficiency decreases. The highest exergy destruction and entropy generation were determined to be 6.25 kW and 0.02134 kW/K, respectively, in HP20 fuel at a power of 5 kW. Entropy generation increases with an increase in the ratio of alcohol in alcohol-based fuels. HEX20 and HP20 fuels produce 25% and 30% more entropy, respectively, compared to G100 fuel. The mass and financial costs of the damage caused by the CO₂ emission of fuels to the environment were determined by conducting four different analyses using energy and exergy analysis data. According to the exergoenvironmental and exergoenviroeconomic analyses, HP20 fuel reached the highest environmental pollution values of 4538.19 kg CO₂/month and 65.804 $/month, respectively. The environmental cost of the CO₂ emission released from the exhaust to the atmosphere is higher in alcohol-based fuels than G100 fuel. As a result of all analyses, it was concluded that hexanol and heptanol could be alternative fuels in spark-ignition engines under particular conditions.

使用汽油-酒精混合物作为火花点火发动机的替代燃料的研究最近获得了动力。在目前的研究中，能源、火用、环境、环境经济、exergoenvironment 和 exergoenviroeconomic 分析通过利用汽油、汽油-庚醇和汽油-己醇燃料（G100、HEX5-20 和 HP5- 20）在单缸四冲程火花点火发动机中以1600转/分的恒速作为不同功率下的燃料。随着燃料混合物中酒精比例的增加，燃料消耗也会增加。NO _X与 G100 燃料相比，醇基燃料混合物的排放更高，CO 和 HC 排放更低。在功率为 5 kW 的 G100 燃料中，最高热效率为 41.09%。随着燃料混合物中酒精比例的增加，热效率降低。在功率为 5 kW 的 HP20 燃料中，最高火用破坏和熵产生分别确定为 6.25 kW 和 0.02134 kW/K。熵产生随着醇基燃料中醇比例的增加而增加。与 G100 燃料相比，HEX20 和 HP20 燃料产生的熵分别增加了 25% 和 30%。CO ₂造成的损害的质量和财务成本通过使用能源和火用分析数据进行四种不同的分析，确定向环境排放的燃料。根据exergoenvironmental 和exergoenviroeconomics 分析，HP20 燃料达到最高环境污染值，分别为4538.19 kg CO ₂ /月和65.804 $/月。与 G100 燃料相比，酒精基燃料从废气中释放到大气中的 CO ₂排放的环境成本更高。所有分析的结果都得出结论，在特定条件下，己醇和庚醇可以作为火花点火发动机的替代燃料。
