Outcomes of advanced biodiesel with nanoparticle additives on performance of CI engines

Abstract

Abstract Biodiesel is a potential alternative fuel source that shows the importance of fossil fuels and helps to keep diesel engines in use for a long time. Numerous research works have shown that biodiesel suffers from its drawbacks, including high viscosity, low volatility, low heat value and high NOx emissions, although some features of biodiesel promote their use, such as CO2, HC, and PM reduce emissions. Some researchers have also noted that these impairments can be overcome with the help of additives and increasing the use of biodiesel. The reduction in harmful effects of emissions on the environment has attracted the attention of researchers towards biodiesel additives. In this work the conclusion of experimental works from different types of additives mixed with jatropha biodiesel is presented. Experimental work includes various nanoparticles such as aluminum (Al), copper (C), zinc oxide (ZnO), carbon nano tubes (CNT), graphene oxide (GO), graphene nanoplates (GNP), carbon nanotubes (CNTs) and multiwalled carbon nanotubes (MWCNTs) etc. In addition to jatropha biodiesel and blends, nano additives reduced the ignition delay period. The combustion process began early, and brake specific fuel consumption decreased as well as an increase in brake thermal efficiency. The effects of various types of biodiesel additives on controlled and uncontrolled emissions of combustion ignition engines have been noted. Their qualities and demerits are also discussed.
