Effects of nano additives with biodiesel fuels in internal combustion engines - A Review

Abstract

In our present world Internal Combustion Engines plays a vital role for transportations, in that engine fuels plays an vital role for transportations, but it causes more emissions. To reduce the emissions and increase the performance of CI engines, many experimental researches are done in alternate fuels in diesel engines and they were found that alternate fuel gives the better performance. Nano particles and nano additives with biodiesels, provide better performance and reduction in emissions. This Literature review reveals about the engines performance and its emissions in CI engines with the effects of addition of nano additives in biodiesels. Nano additives like Al2O3, CeO2, CuO, ZnO, Ag, CNT, MWCNT, and their effects are summarized in this review under different load conditions. The addition of Al2O3 gives better performance. It reduces 7.66% of BSFC at maximum load, increases BTE by 1.58% . 35% of NOx emissions will be reduced with the addition of CNT with biodiesels.
