Pollution-induced environmental deterioration is one of the serious aspects that must be solved. As a result, biodiesel was made from a novel material (Parsley seed oil) through an alkali-induced transesterification reaction. The efficiency, as well as exhaust emission tests, were performed by running the prepared parsley biodiesel blends (mixture of biodiesel and diesel fuel in different proportions) in an engine. The ideal blend for enhancing engine performance was discovered to be B20, which displayed steady performance attributes without requiring any modifications to the diesel engine. The B20 parsley biodiesel blend had fewer emissions than diesel, notably hydrocarbons, and carbon monoxide except for nitrogen oxides and carbon dioxide. B20 Parsley blends were also shown to emit less pollution than other blends (B5 and B10). A high reduction in CO, CO and HC emissions for B20 was recorded at 33.9%, 29.73%, and 11.38% relative to diesel except for NO . Brake-specific energy consumption decreases and thermal efficiency of the engine increases for all biodiesel blends. In addition, from the performance results, BTE and BSFC of B20 are relatively close to those of pure diesel fuel (B0). The use of parsley biodiesel as a diesel engine fuel was shown to be a promising strategy to promote the use of green fuels (biofuels from renewable materials) while simultaneously mitigating the release of toxic greenhouse gases from the combustion of fossil fuel.
污染导致的环境恶化是必须解决的严重问题之一。因此，通过碱催化酯交换反应，利用一种新型原料（欧芹籽油）制备了生物柴油。通过在发动机中运行制备的欧芹生物柴油混合物（不同比例的生物柴油和柴油燃料的混合物）来进行效率以及尾气排放测试。发现用于提高发动机性能的理想混合物是B20，它表现出稳定的性能属性，无需对柴油发动机进行任何改装。B20欧芹生物柴油混合物的排放量比柴油少，尤其是碳氢化合物和一氧化碳，但氮氧化物和二氧化碳除外。B20欧芹混合物的污染排放也比其他混合物（B5和B10）少。相对于柴油，B20的一氧化碳、碳氢化合物排放量大幅降低，分别为33.9%、29.73%和11.38%，但氮氧化物除外。所有生物柴油混合物的制动特定能耗降低，发动机热效率提高。此外，从性能结果来看，B20的制动热效率和制动特定燃油消耗率与纯柴油燃料（B0）相对接近。使用欧芹生物柴油作为柴油发动机燃料被证明是一种有前景的策略，既能促进绿色燃料（来自可再生材料的生物燃料）的使用，同时又能减少化石燃料燃烧产生的有毒温室气体排放。
