摘要

化石燃料的过度消耗加速了全球变暖,并提高了环境空气污染水平。最近的研究探讨了柴油发动机使用替代性环保燃料的可能性,以应对日益增长的石油需求。生物柴油是一种环保的可再生替代燃料。氮氧化物排放量的显著增加是生物柴油最显著的缺点。本研究考察了抗氧化处理的麻疯树生物柴油对VCR柴油机性能和废气排放参数的影响。对于本研究;将100重量ppm的柴油、麻风树生物柴油(B30)和酚类抗氧化剂添加剂二苯胺添加到命名为B30+DPA的B30共混物中。RSM和MCDM的混合方法,如AHP和COPRAS技术,已被用于生成可持续模型,以导出输出响应的最佳模型。从实验结果来看,抗氧化剂显著降低了NOx排放。与B30相比,在测试混合物中加入DPA可将平均NOx排放量和BSFC分别降低7.4%和7.8%。此外,B30+DPA的BMEP比柴油高5.01%和0.38%,B30,CPMax比B30高0.9%,但比柴油低3.4%。发动机输入参数的最佳设置记录在CR为15、7.5%EGR-HOT和12 kg负载时,以获得最佳BP、BMEP、BSFC、CPMax和NOx排放。因此,B30+DPA混合动力适用于提高柴油发动机性能并最大限度地减少废气排放。

A Hybrid Response Surface Methodology and Multi-Criteria Decision Making model to investigate the Performance and Emission Characteristics of a diesel engine fueled with Phenolic antioxidant additive and Biodiesel Blends
Overconsumption of fossil fuels has accelerated global warming and raised environmental air pollution levels. Recent studies have looked into the potential use of alternative, environmentally friendly fuels for diesel engines in response to the rising need for oil. Biodiesel is a renewable alternative fuel that is environmentally friendly. The significant increase in NOx emissions is the most notable disadvantage of biodiesel. This study examined the effect of antioxidant-treated Jatropha biodiesel on the performance and exhaust emission parameters of a VCR diesel engine. For this study; diesel, Jatropha biodiesel (B30) and phenolic antioxidant additive diphenylamine at 100 ppm is added by weight to the B30 blend named as B30+DPA, was used. A hybrid RSM and MCDM approaches such as AHP and COPRAS technique has been used to produce a sustainable model to derive the optimum models for output responses. From experimental findings, the antioxidant significantly reduced NOx emission. The inclusion of DPA to tested blend lowered the average NOx emissions and BSFC by 7.4% and 7.8% respectively as compared with B30. Also, the BMEP of B30+DPA is 5.01% and 0.38% higher than diesel and B30, CPMax is 0.9% higher than B30, but 3.4% lower than diesel. The optimal setting of engine input parameters is recorded at CR of 15, 7.5% EGR-HOT and 12 kg load, for optimum BP, BMEP, BSFC, CPMax and NOx emissions. Therefore, the B30+DPA blend is suitable for enhancing diesel engine performance and minimizing exhaust emissions.
