Abstract: Karanja oil (Pongamia Pinnata) is non-edible in nature and is available abundantly in India. In the present investigation, the oil obtained from the seeds of Karanja is being considered as a potential alternative fuel for CI engine. The Karanja oil extracted from the seeds is converted into Bio-Diesel by the method of esterification. We used different blends such as D100, BD100, BD90 and BD80. The physical properties such as viscosity, calorific value, fire point, flash point and density value are evaluated. Then the performance characteristics like Break thermal efficiency, Brake specific fuel consumption, Exhaust gas temperature and Emission characteristics like opacity, NOX, carbon-monoxide, carbon-dioxide, unburnt hydrocarbons are also determined. During this investigation standard fuel testing procedure are adopted. A single cylinder diesel engine developing 5.2KW is used for investigation. It is found that engine characteristics with neat Biodiesel are found to be inferior compared to diesel with increase in IOP from 180 bar to 200 bar resulted in improvement in engine characteristics
