This work focusses on a novel technique of producing bioethanol from fermented pomegranate fruits waste by using , commonly known as baker's yeast. Four different blends of bioethanol, namely PE10, PE15, PE20, and PE25 were experimented at various operating speeds. It was inferred that the addition of ethanol enhanced the consumption of fuel as well as braking capacity. However, thermal performance was observed to be declined. PE15 blend exhibited optimum brake thermal efficiency at full load condition when compared with unleaded fuel. Brake specific fuel consumption of PE15 was noticed to be lower at different operating speeds among all the blends. Oxides of nitrogen as well as carbon dioxide emissions were increased as the proportion of ethanol in pure fuel was increased. Hydrocarbon and carbon monoxide emissions were reduced, while increasing the ratio of ethanol relative to pure gasoline, except PE10 blend. The combustion characteristics were also studied. Lower value of coefficient of variation revealed stable combustion. This study conclude that PE15 can be used as an alternative fuel.
这项工作聚焦于一种利用通常被称为面包酵母的微生物从发酵后的石榴果实废料中生产生物乙醇的新技术。对四种不同的生物乙醇混合物，即PE10、PE15、PE20和PE25，在不同运行速度下进行了试验。据推断，乙醇的添加提高了燃料消耗以及制动能力。然而，观察到热性能有所下降。与无铅燃料相比，PE15混合物在满负荷条件下表现出最佳的制动热效率。在所有混合物中，PE15的制动比油耗在不同运行速度下均较低。随着纯燃料中乙醇比例的增加，氮氧化物以及二氧化碳排放量增加。除了PE10混合物外，随着乙醇相对于纯汽油比例的增加，碳氢化合物和一氧化碳排放量减少。还研究了燃烧特性。较低的变异系数值表明燃烧稳定。本研究得出结论，PE15可作为替代燃料。
