A comparative study has been undertaken to investigate the production of biodiesel from used cooking oil and performance, emission characteristics of diesel engine using alumina nanoparticles blended biodiesel fuels. The fuel combinations used for the study were pure diesel for base line data generation and Used cooking oil (UCO) Biodiesel and alumina Nano particle blended biodiesel. The biodiesel was prepared from used cooking oil. The alumina nanoparticles were blended with the biodiesel fuel in the mass fractions of 30 ppm and 50 ppm with the aid of an Ultrasonicator. Subsequently, the stability characteristics of alumina blended biodiesel fuels were analyzed under static conditions. The investigation were carried out using an experimental set-up consisting of a single-cylinder four stroke diesel engine coupled with an eddy dynamometer loading device and the results revealed that a considerable higher enhancement in the brake thermal efficiency and substantial reduction in the harmful pollutants for the blend of alumina nanoparticle due to the incorporation of alumina nanoparticle gives more surface area for reactivity and having higher thermal conductivity were observed.
