Abstract : Rapid increase in the rate of fossil fuel depletion has raised concerns all over the world. People are starting to use alternative renewable fuels along with the fossil fuels. One of the largely used alternative fuels is the biodiesel, which can be used directly along with the diesel without making much modification to the engine. The commonly observed disadvantages while using biodiesel- diesel blends are: increased TFC, increased BSFC, decreased BTE and increased NOx emission. The aim of this work is to study the effect of adding nanoparticles in a biodiesel- diesel blend on the performance and emission attributes of a diesel engine. Biodiesel obtained from calophyllum -inophyllum seed oil is used in this study. Nanoparticles of cerium oxide and multi-walled carbon nanotubes are used as additives. The fuel blends used in the experiments are viz-a-viz neat diesel, B20 (20%Biodiesel- 80%Diesel), BCM20 (20%Biodiese -80% Diesel- 20 ppm Cerium Oxide -20 ppm MWCNT) and BCM40 (20%Biodiesel - 80%Diesel- 40ppm Cerium Oxide - 40ppm MWCNT). BTE is increased for BCM20 when compared with B20 and diesel respectively. It is observed that the fuel consumption and emissions such as NO, CO and smoke are decreased for BCM20 and BCM40 blends..
