Study of Effects of Soya Bean and Jatropha Blended Biodiesel on the Performance Parameters of Diesel Engine

Mechanical Engineering

Nowadays, due to rapid growth in the population, it is very hard to maintain adequate supply of natural resources. Fossil fuels and its by-products are one of them. Hence, nowadays biodiesel is used as an alternative for pure diesel which includes less amounts of diesel and different oils, which results in reduction of diesel consumption. In this study, biodiesel was produced from the combination of soya bean and jatropha oil with petroleum diesel fuel. In this study the performance of the diesel engine was checked by using different combinations of diesel, jatropha oil and soya bean oil. Then mechanical efficiency of diesel and different blends of biodiesel is to be calculated and also the emission of CO, CO2, HC, and O2 was calculated and the mechanical efficiency is here compared with the emission of CO, CO2, HC and O2 gives the result. In the study four different blends were tested, first blend is pure form of diesel and other blends are the combination of diesel, soya bean and jatropha oil, that blends are B2 (S10J12D75), B3 (S10J15D70), B4 (S10J18D65), where as B2, B3, B4 are the blends and S is percentage of soya bean oil, J is percentage of jatropha oil and D is the percentage of diesel and here the catalyst is to be used is ethanol for transesterification process. Here, the comparison between the four different blends with the emission of CO, CO2, HC, O2 is to be done on the basis of two input parameters that is, change in variable compression ratio and change in loads. This all to calculate by using software internal combustion engine which is directly attached with diesel engine and gives the results.
