The limited amount of petroleum resources have caused interests in the development of alternative fuels for internal combustion (IC) Engines. As an alternative, biodegradable, renewable and sulphur free biodiesel is receiving increasing attention. The use of biodiesel is rapidly expanding around the world, making it imperative to fully understand the impacts of biodiesel on the diesel engine combustion process. An experimental investigation has been carried out to analyze the performance characteristics of a compression ignition engine fuelled, first the experiment is performed with diesel, pure karanja oil and then with blends of karanja oil and diesel (75-25%, 50-50% and 25-75 %) and it is denoted by K75, K50 and K25 respectively. A series of engine tests, have been conducted using each of the above fuel blends for comparative performance evaluation. The results indicate that the performance of engine is improved with K75 blend. At full load condition, K 75 blends produce 3.78% more brake horse power & it is maximum as compare to diesel. The brake thermal efficiency of K 75 blend at full load condition is 0.93 % more than sole Diesel. Hence it can be concluded that the karanja oil (K75 blend) is a suitable alternative fuel for diesel.
