Combustion behaviour of ZnO nanoparticles added algae biodiesel on CI engine

Abstract

In experimental research studies, the emission qualities of a direct injection diesel engine powered by neochloris oleoabundans methyl ester and its blends with zinc oxide nanoparticles as a fuel additive are examined. Neochloris oleoabundans methyl ester is made from the transesterification process of untreated neochloris oleoabundans algae oil. By dispersing the catalyst of ZnO nanoparticles using the ultrasonic process, the fuel is customised. Different diesel-biodiesel-ZnO blends were prepared by varying the biodiesel engine in order to evaluate its combustion properties on a single cylinder, CI engine as well as nanoparticle proportions of 25, 50, 75 and 100 ppm of ZnO nanoparticles. The final outcomes revealed that together with 100 ppm ZnO nano additive, the acceptable nano blend that results in better engine efficiency is B20. Thermal efficiency is improved at this rate and all CO and HC emissions are released.
