Presently, the reduction of emission rates from the diesel engine is a significant aim of several researchers. Biodiesel has considered an alternative for diesel, but based on mechanical efficiency, its performance is very poor. Therefore, the nanoparticles are blended with the diesel and biodiesel for reducing emission and enhancing the engine performance characteristics. The major intention of the present work is to provide the finest fuel blend for the 4-stroke diesel engine according to both emission and combustion characteristics. Here, the Hazantus (algae bio diesel) prepared via soxhlet extraction, and then it is blended with the diesel under three various ratios such as 1:9, 2:8, 3:7. Based on these three ratios, the performance of the variable compression ratio engine has been investigated and is optimized by using the Taguchi method, which exhibited that the 2:8 biodiesel blend is optimum based on mechanical performance and combustion. Further, to enhance biodiesel performance concerning emission characteristics, the cerium oxide nanoparticles mixed with the optimum fuel blend at the proportion rate of 25 and 50 mg. The emission rates obtained from this research work are 1000PPM of NOx, 0.052% of CO, and 38% of HC.

利用田口和方差分析方法优化添加氧化铈的藻类生物柴油混合物的排放和燃烧特性

目前,降低柴油发动机的排放率是几位研究人员的重要目标。生物柴油曾考虑替代柴油,但基于机械效率,其性能很差。因此,纳米粒子与柴油和生物柴油混合以减少排放并提高发动机性能特征。目前工作的主要目的是根据排放和燃烧特性为四冲程柴油发动机提供最好的燃料混合物。在这里,Hazantus(藻类生物柴油)通过索氏提取法制备,然后与柴油以 1:9、2:8、3:7 三种不同的比例混合。在这三个比率的基础上,对可变压缩比发动机的性能进行了研究,并使用田口方法进行了优化,这表明基于机械性能和燃烧,2:8 的生物柴油混合物是最佳的。此外,为了提高生物柴油在排放特性方面的性能,氧化铈纳米颗粒与最佳燃料混合物以 25 和 50 毫克的比例混合。从这项研究工作中获得的排放率为 1000PPM 的 NOx、0.052% 的 CO 和 38% 的 HC。
