Abstract:
In this study, the effects of incorporating cerium oxide into diesel and WPO blends were investigated to determine the potential of the blend as a fuel additive. The study aimed to assess engine-performance, emission, and combustion properties of the blend. The experiments utilized a single-cylinder diesel engine, and researchers prepared two different blends of WPO with 25% WPO in diesel and 50% WPO in diesel. Cerium oxide was added to these blends at concentrations of 25 ppm and 50 ppm using an ultrasonicator. The results demonstrated that increasing cerium oxide content in the blend (50 ppm) led to reduced CO, HC, and NOx emissions at higher loads. For instance, B50 + 50 ppm exhibited lower CO and NOx emissions, while B25 + 50 ppm demonstrated lower HC and smoke emissions. Furthermore, raising the CeO2 content from 25 ppm to 50 ppm resulted in a 3% increase in brake thermal efficiency. Moreover, cerium oxide positively impacted combustion and performance properties of the blends. Among the tested blends, the B50 + 50 ppm combination showcased the highest brake thermal efficiency, optimal air-fuel ratio, and the lowest specific fuel consumption. In conclusion, employing cerium oxide as a fuel additive in diesel-WPO blends offers a promising approach for realizing a sustainable and environmentally friendly future.
摘要:
在这项研究中,研究了将氧化铈掺入柴油和WPO共混物中的影响,以确定该共混物作为燃料添加剂的潜力。这项研究旨在评估发动机性能,发射,和燃烧性能的混合物。实验采用单缸柴油机,研究人员制备了两种不同的WPO混合物,其中柴油中的WPO含量为25%,柴油中的WPO含量为50%。使用超声波发生器将氧化铈以25ppm和50ppm的浓度添加到这些共混物中。结果表明,增加共混物中的氧化铈含量(50ppm)导致CO减少,HC,和NOx排放在较高的负载。例如,B50+50ppm表现出较低的CO和NOx排放,而B25+50ppm显示出较低的HC和烟雾排放。此外,将CeO2含量从25ppm提高到50ppm导致制动热效率提高3%。此外,氧化铈对共混物的燃烧和性能性能产生积极影响。在测试的混合物中,B50+50ppm组合展示了最高的制动热效率,最佳空燃比,和最低的燃料消耗率。总之,在柴油-WPO混合物中使用氧化铈作为燃料添加剂为实现可持续和环境友好的未来提供了有希望的方法。
