Biofuel is a renewable fuel and can be used as a replacement for diesel. Pyrolysis oil can be derived from non‐edible de‐oiled seed cakes. This investigation focuses on the exergy investigation of a compression ignition (CI) engine to maximize the work exergy (availability) and minimize the destroyed exergy, powered by Aegle marmelos (AM) de‐oiled seed cake bio‐oil blends. A dual blend of diesel and AM pyrolysis oil was taken in ratios, F0 = 100 + 0, F5 = 95 + 5, F10 = 90 + 10, F15 = 85 + 15, and F20 = 80 + 20 and were tested on a constant speed CI engine at standard compression ratio. The investigational analysis exhibited that a high amount of oxygen content in AM pyrolysis oil blends increased the brake thermal efficiency and decreased the brake‐specific fuel consumption compared with diesel (F0). The owing exergy efficiency was obtained from the F20 blend (57.21%) at 100% load (W). Based on the investigation, considering availability and performance behavior of F5, F10, F15, and F20 blends were suggested as suitable biofuel alternatives to diesel.

装有Aegle marmelos脱油种子饼热解油opus的柴油发动机的火用分析

生物燃料是一种可再生燃料，可以用作柴油的替代品。热解油可以来自不可食用的脱油种子饼。这项研究的重点是由Aegle marmelos提供动力的压燃式（CI）发动机的火用研究，以最大程度地提高工作火用（可用性）并最大程度减少被破坏的火用。（AM）脱油的种子饼生物油混合物。柴油和AM热解油的双重混合物的比例为F0 = 100 + 0，F5 = 95 + 5，F10 = 90 + 10，F15 = 85 + 15和F20 = 80 + 20标准压缩比的高速CI发动机。研究分析表明，与柴油（F0）相比，AM热解油混合物中的大量氧气含量提高了制动器的热效率，并降低了制动器的比油耗。由F20共混物（57.21％）在100％负荷（W）下获得的火用效率。在调查的基础上，考虑到F5，F10，F15和F20混合物的可利用性和性能，被认为是柴油的合适生物燃料替代品。
