Abstract: Use of biodiesel as an alternative to diesel could reduce the dependency on petroleum product and the pollution problems. Increasing injection pressure is beneficial for achieving better atomization which will directly increase the surface area of injected fuel. In this paper the performance of different blends such as 10B (10% neat Karanja oil and 90% diesel), 20B, 30B, 40B and 100% diesel compared at different injection pressure 150bar, 170bar, 190bar and 210bar.It is found that as the injection pressure increases the brake thermal efficiency (BTE), also increases and brake specific fuel consumption (BSFC) is lowered as the injection pressure is increases. In the present work, experiments are conducted on 3.72 kW (5 BHP) single cylinder, four stroke, air-cooled diesel engine using neat Karanja oil blended with diesel in various proportions to study the engine performance.
