Abstract :

This paper investigate the scope of utilizing biodiesel with high bland (B20 & B40) developed from the Methyle alcohol from pongamia oils as an alternative diesel fuel. The major problem of using neat pongamia oil as a fuel in a compression ignition engine arises due to its very high viscosity. Transesterification with alcohols reduces the viscosity of the oil and other properties have been evaluated to be comparable with those of diesel. In the present project work, an experimental investigation is carried out on performance and emission characteristics of preheated higher blends of pongamia biodiesel with diesel. The higher blends of fuel is preheated at 60, 75, 90 and 110˚C temperature using waste exhaust gas heat in a shell and tube heat exchanger. Transesterification process is used to produce biodiesel required for the project from raw pongamia oil. Experiments were done using B20 and B40 biodiesel blends at different preheating temperature and for different loading. A significant improvement in performance and emission characteristics of preheated B40 blend was obtained. B40 blend preheated to 110˚C showed maximum 8.72% and 8.97% increase in brake thermal efficiency over diesel and B20 blend respectively at 75% load. Also the highest reduction in UBHC emission and smoke opacity values are obtained as 79.41% and 80.6% respectively over diesel and 78.12% and 73.54% respectively over B20 blend for B40 blend preheated to 110˚C at 75% load. Thus preheating of higher blends of diesel and biodiesel at higher temperature improves the viscosity and other properties sharply and improves the performance and emission.
