Effect of Hybrid Nano-Additives on Performance of Biofuel in Diesel Engine

Humanity has been compelled to contemplate numerous alternative fuels because of the ever-increasing demand and cost of petroleum-based products. Numerous experimental studies on alternative fuels in diesel engines have been conducted in order to decrease emissions and improve performance of CI diesel engines. A major respondent in the alternative fuels industry at the moment is bio-diesel, which can be employed in any diesel engine. The use of nanoadditives to diesel-biodiesel fuel mixes has further shown notable outcomes. They improved the qualities of biofuel, which resulted in better efficiency and a significant drop in emissions. The emphasis of the current work is on the impact of bio-diesel nanoadditions on efficiency and emission levels of CI engines. The paper aims to review the use of metal oxide nanoadditives and the growing utilization of hybrid nanoadditives. nanoadditives like Al 2 O 3 , CeO 2 , graphene oxide, TiO 2 and recent works in hybrid additives have been discussed. It is found that emissions of carbon dioxide, hydrocarbon and carbon monoxide have been significantly decreased, which allowed diesel engines to operate at their full potential.
