ABSTRACT Energy utilisation from renewable sources plays a vital role in meeting the demands of a clean environment. Commercialisation of biodiesel is comparatively less than that of other alternative sources due to its suitability and yield. This paper is focused on performance and emission characteristics of neem oil biodiesel and cotton seed oil biodiesel blended with cerium oxide as an additive. The blending proportion was B10, B20, B30, B40 and 100% diesel. The testing was performed in a single-cylinder diesel engine coupled with an exhaust gas analyser. The performance characteristics were obtained in between the brake power with specific fuel consumption and emission characteristics such as carbon monoxide, carbon dioxide and other gases. It was observed that the combination of B20 proportion with CeO2 blend produces effect results with other blends in specific fuel consumption and reduced emission behaviour.
