Performance and Emission Characteristics of Single-Cylinder Diesel Engine Fueled with Biodiesel Derived from Cashew Nut Shell

In several countries, the construction of the industrial production of biofuels to limit the use of fossil fuels has been encouraged. The purpose of this study is to use cashew nutshell (CNS) oil with copper oxide nanoparticle as biodiesel to carry renewable fuel and to alleviate the extreme problems faced by depleting oil reserves. Oil. Transesterification process converts the CNS into biodiesel. The combined mixture in a 20% increase of diesel is then tested with a single-cylinder engine for output and combustion. The biodiesel–diesel mixes’ performance and pollution feature and considers the chosen diesel blend. The performance and emission characteristics of a single-cylinder compression ignition engine and stated a negligible decrease in BTE and surge in particulate matter emissions for blends when compared to diesel. This paper generally finds that CNS biodiesel provides several advantages including sustainability, elimination of toxic emissions, based on different studies.
