Performance and emission analysis of palm and jatropha biofuel blends with diesel on an unmodified CI Engine

The shortage of petroleum reserves today in collaboration with the abundance in availability of plant and forest based non edible vegetable oils has increased the demands of using these vegetable oils as substitutes of diesel. The common vegetable oils that can be used are palm, jatropha, coconut, castor etc. In my research, by careful literature survey, I have used Palm and Jatropha oil blends and their combined blends with diesel. But before testing the Biodiesel in a Compression Ignition engine we had make sure that the biodiesel derived from neutralized jatropha and palm oil is suited for use in diesel engines given that its kinematic viscosity, flash point, cloud point, and calorific value conform to the recommended international standards. After this conformation, we have carried out the performance and emission analysis to get an idea about the practicality of the use of Jatropha and Palm oil as an alternative fuel. This paper present experimental results in which different oil blends were tested in an unmodified CI engine to evaluate its performance and emission characteristics with respect to engine speed.
