Performance Study of IC Engine fueled with Biodiesel and its Blend Obtained from Waste Cooking Oil

The demand for alternate energy has increased which resulted in exploiting waste cooking oil (fried oil). This fried oil is transesterified to biodiesel. By using microwave assisted conventional process transesterification is done. The presence of fatty acid methyl ester (FAME) was confirmed by Fourier transform infrared spectrometer (FTIR) analysis. The peaks obtained around 1741cm-1 confirmed the presence of ester carbonyl bonds. The properties like fire point, flash point, density and viscosity were determined for biodiesel and for blends (B10:D90 and B20:D80). The values obtained suggested that the quality of the biodiesel was found to improve when it was blended with diesel. The blends were used to study the performance and emission characteristics of internal combustion engine. Pure diesel was used as reference. The engine performance test including parameters like brake power (BP), brake thermal efficiency (BTE), indicated thermal efficiency (ITE), mechanical efficiency ηME were determined and were found to increase with increase in load. Emission characteristics like HC, NOX, CO, CO2 and SOX for pure diesel and for the blends are found. Overall, the performance of the IC engine was found to improve when biodiesel was blended with diesel
