ABSTRACT

In this experimental investigation, the impact of engine load, compression ratio, and percentage blends of biofuel on exergy, energy, and sustainability parameters for the samples of diesel based (10–40% v/v) biodiesel blends were performed on variable compression ratio engine. The brake thermal efficiency, exergy efficiency, engine sustainability, exergy destruction rate, and other exergy parameters were found to escalate with the escalating engine load, compression ratio, and percentage of Shorea robusta methyl ester biodiesel fuel blends. The exergy and energy efficiency of the engine with diesel fuel were 2.05%, 6.98%, and 10.63%, respectively higher than 10%, 30%, and 40% Shorea robusta methyl ester fuel and 2.23%, 8.67%, and 9.22%, respectively at 50% engine load and 1500 rpm engine speed.

The influence of compression ratio, engine load, and fuel blends on the exergetic performance parameters revealed a similar trend with energetic parameters, but the magnitude of exergy parameters was found lower than the energetic parameters. The application of Shorea robusta methyl ester biodiesel blends improved the combustion characteristics with a small drop in energy and exergy performance parameters and sustainability of the engine. The exergy destruction rate and entropy generation rate for shorea robusta methyl ester biodiesel blend were found lower than the conventional fuel. Therefore, the fuel blend have a high potential to be an alternate to the conventional fuel without any design modification of diesel engines.

Shorea Robusta 甲基酯生物柴油混合物对柴油机火用和可持续性分析的影响

摘要

在本实验研究中,发动机负载、压缩比和生物燃料混合百分比对柴油基(10-40% v/v)生物柴油混合样品的火用、能量和可持续性参数的影响是在可变压缩比下进行的引擎。发现制动热效率、火用效率、发动机可持续性、火用破坏率和其他火用参数随着发动机负载、压缩比和 Shorearobusta 甲基酯生物柴油燃料混合物百分比的增加而增加。柴油发动机的火用和能源效率分别为2.05%、6.98%和10.63%,分别高于10%、30%和40%的Shorerobusta甲酯燃料和2.23%、8.67%和9.22%,分别在 50% 发动机负载和 1500 rpm 发动机转速下。

压缩比、发动机负荷和混合燃料对火用性能参数的影响显示出与能量参数相似的趋势,但发现火用参数的大小低于能量参数。Shorearobusta 甲基酯生物柴油混合物的应用改善了燃烧特性,能量和火用性能参数和发动机的可持续性略有下降。发现shorearobusta 甲基酯生物柴油混合物的火用破坏率和熵产生率低于传统燃料。因此,该燃料混合物具有成为传统燃料替代品的巨大潜力,无需对柴油发动机进行任何设计修改。
