ABSTRACT

A study of the existing literature on the effects of diethyl ether with different biodiesels such as Fish, Neem, Calophyllum Inophyllum, Cottonseed, and Soybean biodiesel was undertaken. Till date, no study related to the combined effects of repurpose used cooking oil biodiesel/diethyl ether/diesel blends and different compression ratios with different loading conditions has been reported in the literature. Moreover, the current study reveals that there are some major flaws in the existing scenario such as no reduction in harmful exhaust gases such as carbon dioxide, hydrocarbon, carbon monoxide, and nitrogen oxide. There is no noticeable improvement in the performance characteristics such as brake thermal efficiency and brake specific fuel consumption. This investigation has been carried out for controlling harmful emissions and improving the performance of the engine. The present study investigates the combined impact of compression ratios on emission and performance characteristics of a diesel engine using ternary blends in comparison with diesel. This study provides eco-friendly working conditions that result in fewer emissions with improved performance. The results show that a higher compression ratio is useful for minimizing nitrogen oxide emission, while a lower compression ratio is useful for minimizing carbon monoxide emission. CR16 works effectively with a higher proportion of diethyl ether (2.4 and 3.2%) and provides better results for minimizing emissions with improved performance. The following eco-friendly blends delivered lower emissions with improved performance. These blends are: A0.8_B19.2: CR16 and CR15; A1.6_B18.4: CR17 and CR16; A2.4_B17.6: CR16, CR15, and CR14; A3.2_B16.8: CR16 and CR15.

摘要

对现有文献进行了研究，研究了乙醚对鱼类，印em，茶树，棉花籽，棉籽和大豆生物柴油等不同生物柴油的影响。迄今为止，尚未有文献报道再利用过的食用油生物柴油/二乙醚/柴油混合物的混合作用以及在不同的负载条件下不同的压缩比。此外，当前的研究表明，在现有方案中存在一些重大缺陷，例如没有减少有害废气，例如二氧化碳，碳氢化合物，一氧化碳和氮氧化物。在诸如制动器热效率和制动器特定燃料消耗的性能特征上没有显着的改善。已经进行了这项研究以控制有害排放物并改善发动机性能。本研究调查了与柴油相比，压缩比对使用三元混合物的柴油机排放和性能特征的综合影响。这项研究提供了环保的工作条件，可减少排放并提高性能。结果表明，较高的压缩比对于最小化氮氧化物排放是有用的，而较低的压缩比对于最小化一氧化碳排放是有用的。CR16与较高比例的乙醚（2.4％和3.2％）一起有效地工作，并提供了更好的结果，可最大程度地减少排放并提高性能。下列环保型共混物可降低排放，并提高性能。这些混合是：A0.8_B19.2：CR16和CR15；A1.6_B18.4：CR17和CR16；A2.4_B17.6：CR16，CR15和CR14；A3.2_B16.8：CR16和CR15。
