Production and Application of Bio-diesel in Compression Ignition Engine

The continuous increasing demand for energy and diminishing tendency of petroleum resources has led to the search for alternative renewable and sustainable fuel. Biodiesel seems to be a solution for future and being viewed as a substitute of Diesel. The vegetable oil, fats, grease are source of feedstock for the production of biodiesel. Out of four methods viz. dilution, micro emulsion, thermal cracking and Transesterification, the last one is used to produce biodiesel and reduce viscosity. Biodiesel is more suitable for use as an engine fuel rather than straight vegetable oils for a number of reasons; the more notably is its low viscosity. The aim of the paper at hand is towards the production of biodiesel from vegetable oils viz. Karanja, Jatropha by Transesterification process. Fuels were manufactured by direct blending 5% of biodiesels, namely, Karanja and Jatropha and Rice Bran vegetable oil using Magnetic stirrer. The physical properties of the fuels were also found out. Later, these fuels were run in Compression Ignition engines to test and compare the performance and pollution characteristics of fuels.
