The performance and emission characteristics of CI Engine are investigated using Magnetite (Fe3O4) Nanoadditive with waste cooking oil Biodiesel Blend. The samples studied in this work are diesel oil, B20, B20M25 (B20+25ppm), B20M50 (B20+50ppm.), B20M75 (B20 +75ppm) and B20M100 (B20 +100ppm). Physio-Chemical properties of above samples are determined and the test results showed that the calorific value, density and viscosity increases with increase in Nanoadditive concentration. The performance of CI engine was investigated using CI engine test rig at constant injection pressure 200 Bar and compression ratio 17.5 by varying the load. From the experimental investigation it is found that B20M100 has improved performance and emission characteristics compared to B20. At full load for B20M100 blend, BTE increases by 1.49% and BSFC decreases by 2.21% when compared to B20 blend. NOX, CO and smoke opacity emission decreases by 7.43%, 2.08% and 10.43% respectively for B20M100 compared to B20 at full load.
