Due to the expansion of industrialization, diesel consumption is increasing and due to which a global increase in pollution and depletion of energy sources is inevitable. Biodiesels have emerged as a solution to this problem. Still, the performance of biodiesels in the compressed ignition engine is not comparable to diesel. The use of additives in biodiesel has been found to increase their efficiency. Nanoparticles as biodiesel additives have been garnering lots of attention as a very small amount could have a significant impact on engine performance. Engine performance parameters improve due to the presence of nanoparticles. Also, emission characteristics have been found to reduce.
