This paper collectively report work of many researchers on engine operation and emissions of diesel engine with alumina nanoadditive in diesel blends. Fuel blending is a very common and popular practice as compared to making changes in engine design or treating the exhaust gases for hazardous emissions. Alumina nanoadditive related findings are encapsulated here to review the pros and cons of various alternative fuels for better performance and reduced harmful emissions. Many recent researches are now focussed on nanoadditive over microadditives for their high specific surface area, much better combustion characteristics than micron sized additives and shorter ignition delays. Easy dispersion and suspension in liquid fuels can be obtained by Nanoparticles. This review focus on the effect of alumina nanoadditives on the fuel efficiency, brake thermal efficiency, emissions and a summary of the observation from literature is presented here.

氧化铝纳米添加剂对柴油机运行和排放特性的影响

本文共同报告了许多研究人员在掺混氧化铝纳米添加剂的柴油机的发动机运行和排放方面的工作。与更改发动机设计或处理废气中的有害排放物相比，混合燃料是一种非常普遍和普遍的做法。此处封装了与氧化铝纳米添加剂相关的发现，以审查各种替代燃料的优缺点，以实现更好的性能并减少有害排放。由于其高的比表面积，比微米级添加剂好得多的燃烧特性和更短的点火延迟，现在许多新的研究集中在纳米添加剂上，而不是微米添加剂上。纳米颗粒可以使液体燃料易于分散和悬浮。这篇评论主要关注氧化铝纳米添加剂对燃油效率的影响，
