Animal flesh is a major food source with economic and industrial value for consumer demand. These meats produced biowaste during and after preparation and use. Chicken intestines make up most of the waste thrown away after processing or frying. This study considers it a biodiesel source. Transesterification turns chicken intestine waste fat oil into biodiesel. This oil is used in compression ignition (CI) engines but performs poorly compared to diesel. Diesel, the base fuel, is mixed with 20% biodiesel. The remaining 10% and 20% of butanol and pentanol are port fuels, improving combustion and lowering emissions in the 5.2 kW, 1500 rpm CI engine. 20% pentanol premixing outperformed butanol premixing, blending, and engine CIWFOB operation. The greater heating value improves combustion, therefore 20% pentanol premixing with blend produces 32.76% BTE, 10.57% more than diesel. It produced 55.18% less CO and 50.92% less smoke than diesel, which has a greater heat release rate (48.86 J/CAD) and peak pressure (64.76 bar). This premixing costs NOx emissions. The CIWFOB blend with 20% pentanol premixing improves engine performance. For SDGs 7, 9, 12, and 13, this study is supported.
动物肉是一种主要的食物来源，对消费者需求具有经济和工业价值。这些肉类在制备和使用过程中及之后会产生生物废弃物。鸡肠构成了加工或油炸后丢弃的大部分废弃物。本研究将其视为生物柴油来源。酯交换反应将鸡肠废弃物脂肪油转化为生物柴油。这种油用于压燃式（CI）发动机，但与柴油相比性能较差。以柴油为基础燃料，与20%的生物柴油混合。其余10%和20%的丁醇和戊醇作为端口燃料，可改善5.2千瓦、1500转/分钟的CI发动机的燃烧并降低排放。20%戊醇预混在性能上优于丁醇预混、混合以及发动机CIWFOB运行。更高的热值改善了燃烧，因此20%戊醇与混合燃料预混产生了32.76%的制动热效率，比柴油高出10.57%。它产生的一氧化碳比柴油少55.18%，烟雾比柴油少50.92%，柴油具有更高的热释放率（48.86焦/曲轴转角）和峰值压力（64.76巴）。这种预混会增加氮氧化物排放。20%戊醇预混的CIWFOB混合燃料提高了发动机性能。本研究符合可持续发展目标7、9、12和13的要求。
