Abstract: Vegetable oils are a potential alternative to partial or total substitution of diesel fuels. In this study, we used Acetone as an additive to investigate the possible use of increased percentages of biodiesel in diesel engine without any retrofitting. In this study, performance tests were carried out on diesel engine with neat diesel fuel and biodiesel mixture. Biodiesel was made by transesterification process. Karanja oil was selected for biodiesel production. Number 2 diesel fuel containing 30% biodiesel and 70% diesel fuel, is called here as B30. The effects of Acetone, blended with B30 in 4, 8, 12 % by volume were used in a single cylinder, four strokes direct injection diesel engine. The effect of test fuels on engine torque, power, brake specific fuel consumption, brake thermal efficiency, exhaust gas temperature, were ascertained by performance tests. The influence of blends on CO, CO2, HC, NO and smoke opacity were evaluated by emission tests. The experimental results showed that the exhaust emissions were fairly reduced for 12% Acetone with B30; especially the NO is reduced remarkably by 48% while comparing diesel operation.
