Effect of CuO nanoparticles concentration on the performance and emission characteristics of the diesel engine running on jojoba (Simmondsia Chinensis) biodiesel

The utilization of the petroleum products in engines is harmful to the humans as they pollute the environment. Nowadays, extensive research is in process to find an alternative fuel and improve its quality. The nanoparticles are one of the recent technologies that is useful for upgrading the fuel properties. This work aims to find the influence of CuO nanoparticles on performance of diesel engine, emission and combustion characteristics which runs on jojoba biodiesel blend (JB20) as a fuel. Different proportions of CuO nanoparticles (25, 50, and 75 ppm) were dispersed into the JB20 fuel. It is experimentally seen that BTE for the JB20CN50 fuel was higher than that of other Jojoba biodiesel fuel samples. The combustion characteristics such as ignition delay, HRR and cylinder pressure were also determined for analysing the effect of CuO nanoparticles. Engine emission hydrocarbons, CO and smoke emissions were also found lesser when the CuO nanoparticles added to JB20.
