Abstract

In this research paper a study is done on the performance and emission characteristics of CI engine when it is fuelled with Jatropha biodiesel having Titanium dioxide nanoadditives. Biodiesel is obtained through transesterification from Jatropha oil. TiO2 nanoparticles are used as nanoadditives through sonication process. Biodiesel blend, compression ratio and nanoadditive concentration are chosen as the parameters to be studied. Taguchi analysis is used to reduce the experimentation work. The combination of parameters to be experimented is obtained from the Minitab software. It is observed that fuel samples with B20 blend and at18:1 compression ratio give out better performance and emission characteristcs. The effect of nanoadditive is significant when the concentration is 75 mg/l compared to other blends tested.
