Abstract
An innovative idea have been proposed in this work, to increase fuel efficiency and minimize emission from Diesel engine. This research mainly focuses on the systhesis of two nano materials namely MgO, TiO2. The synthesized nano additives was blended in equal proportion with Biodiesel prepared from Watermelon seed oil through the process of trans-esterification. Then 20% Biodiesel was mixed with 80% diesel and now the fuel is called as B20. Equal proportion of MgO and TiO2 mixture was prepared which is called as Nano Additive Mix(NAM) and added with B20 blend. A 5HP mono Barrel Diesel engine was powered with B20 and with various proportion of NAM in the range of 50ppm, 100ppm, 150ppm and 200ppm. The results obtained revealed that B20 blended with NAM150 minimized CO, HC and Smoke emission considerably when equated to other mixtures. The BTE at peak load for Diesel was 28.4% and for the same load it was 28.2% for B20 @ NAM150 blend. The B20 with 150NAM blend become the best alternative fuel combination to operate the engine with less emission and best fuel consumption and power output.
