Abstract

Biofuel is an alternative fuel for diesel engines which is necessary to reduce exhaust emissions and helps to balance the depletion of fossil fuels. This study details the synthesis of bio-diesel and bio-oil from stone apple seeds ( Aegle marmelos) through transesterification, direct oxygenate additive, and pyrolysis processes. The diesel engine is powered by the resulting stone apple methyl ester bio-diesel/diesel and bio-oil/diesel mixtures. In a test engine rig, the effectiveness and emission uniqueness of test fuel mixes were examined at various engine loads (EL = 3 kg–12 kg) and compression ratios (CR = 16–17.5) while maintaining a steady speed of 1500 r/min. Furthermore, engine performance and emissions for bio-diesel and bio-oil are measured and compared. The oxides of nitrogen (NOx) emission by bio-diesel and bio-oil opus were higher than neat diesel (FD). Also, carbon monoxide (CO) and hydrocarbon (HC) emissions were measured to be lower. The improvements of BTE by 4.87% and decrement of CO by 18.8%, HC by 13.26% were observed with the trans-esterified bio-diesel/diesel opus compared to diesel at a higher CR and rated load conditions. The engine analysis responses revealed that the FBD blend showed enhanced performance and lower emissions except NOx compared to diesel fuel. Hence, trans-esterified bio-diesel is a greater diesel alternative than FBDE and FBO.

利用石苹果籽（Aegle marmelos）提取的生物柴油和生物油作为生物能源的燃料和发动机性能研究

生物燃料是柴油发动机的替代燃料，对于减少废气排放和平衡化石燃料的消耗十分必要。本研究详细介绍了通过酯交换、直接含氧添加剂和热解工艺从苹果籽（Aegle marmelos）中合成生物柴油和生物油的过程。柴油发动机由生成的砀山苹果甲酯生物柴油/柴油和生物油/柴油混合物提供动力。在发动机试验台架上，在不同的发动机负荷（EL = 3 kg-12 kg）和压缩比（CR = 16-17.5）条件下，测试燃料混合物的有效性和排放独特性，同时保持稳定转速为 1500 r/min。此外，还对生物柴油和生物油的发动机性能和排放进行了测量和比较。生物柴油和生物油的氮氧化物（NOx）排放量高于纯柴油（FD）。此外，一氧化碳（CO）和碳氢化合物（HC）的排放量也较低。在较高的压缩比和额定负载条件下，与柴油相比，转酯化生物柴油/生物柴油 opus 的 BTE 提高了 4.87%，CO 降低了 18.8%，HC 降低了 13.26%。发动机分析结果表明，与柴油相比，生物柴油/柴油混合燃料的性能更佳，除氮氧化物外，排放更低。因此，与 FBDE 和 FBO 相比，转酯化生物柴油是一种更好的柴油替代品。
