摘要: 采用过氧化方法对生物柴油进行燃料改性,探讨了过氧化改质的机理,测量并分析了过氧化改质对生物柴油粘度和过氧化值的影响。在170F柴油机上,对过氧化改质前、后生物柴油进行台架试验,考察了过氧化改质对生物柴油NOx排放和碳烟的影响。研究结果表明:过氧化改质后,脂肪酸甲酯碳链中的双键被打断,饱和程度增加,氧化安定性得到明显改善,动力粘度最大可降低8.2%;燃用过氧化改质生物柴油,标定转速、各个负荷下,NOx和碳烟同时下降。

Abstract: Biodiesel was redesigned by peroxidation. The mechanism of peroxide modification was discussed. The viscosity and peroxide value of biodiesel before and after peroxide modifications were measured and analyzed. Experiments were carried out in a 170F engine fueled with biodiesel and peroxide biodiesel, and the impacts of peroxide modification on NOx emissions and carbon smoke were studied. The results show that the carbon double bonds of fatty acid methyl esters are broken after peroxide modification, the degree of saturation is increased, oxidation stability is improved significantly, and dynamic viscosity of biodiesel is much lower than that of biodiesel up to a maximum of 8.2%. Both NOx emission and carbon smoke decrease for the investigated operating conditions.

Key words: power machinery engineering, biodiesel, peroxide modification, oxidation stability, carbon smoke, NOx
