A research study was conducted with the objective to produce biodiesel from nonedible oil of karanja (pongamia pinnata) and to evaluate the performance characteristics and efficiency for different types of fuel; diesel, diesel-karanja biodiesel and dieselkaranja biodiesel with additive when operate on a diesel engine. The presence of free fatty acid in the crude Karanja oil was more than 4%, hence it undergoes a two-step transesterification process. The process involves pre-treatment of crude Karanja oil by acid catalyzed transesterification and followed by based catalyzed transesterification process with methanol as reactant in the presence of H2SO4 and NaOH as the catalyst respectively. The maximum yield of biodiesel was found out to be 79.8% with a 9:1 ratio of methanol to oil. Apart from that, the test fuels characterization was conducted using Fourier Transform Infrared Spectroscopy (FT-IR) and bomb calorimeter. Based on the analyses performed, B10, B10P5 and B10P10 have a calorific value of 43.5668 MJ/kg, 43.4332 MJ/kg and 42.7761 MJ/kg respectively. The FTIR results indicate that both diesel and Karanja biodiesel have the same functional group of C-H (hydrocarbons). Moreover, diesel engine performance test were conducted at the speed range of 1500 rpm to 2000 rpm for four types of fuel blends to indicate its brake horse power, brake specific fuel consumption and mechanical efficiency.
