Abstract

The current scenario and the major crisis faced by automotive sector throughout the world is the depletion of fossil fuels and toxic, fatal emissions pushed out through the tailpipe of internal combustion engine. Especially the emissions from compression ignition engine has to be taken care of and with the help of technological development many are seeking to invent techniques and procedure to replace and keep aside diesel fuel with alternate fuels and especially bio-derived combustion fuels. In the recent year scientist have came up with ideas to replace diesel fuels and there are suggestions that bio oil- diesel blend bio fuels along with alcohol and other combustion enhancement or property improvement mixtures can do and bring acceptable changes with fulfilling the requirements. Former scientific investigations have presented that biodiesel and various blends can reduce emissions and improve performance of a diesel engine. In this current investigation rice bran oil-diesel blend and camphor were prepared to check its effect of performance and emission character in a compression ignition engine. Biodiesel was prepared in single stage alkaline trans-esterification process and after then biodiesel-diesel-camphor blend were prepared as B20, B30. These blends were tested in a single cylinder, diesel engine with rated power of 5KW, performance and emission data are compared with that of baseline commonly used diesel. Further it was noted with usage of bio diesel-diesel blends the NO_x emission increases and in this investigation titanium dioxide a photocatalyst which has the capability to react with NO_x in presence of a light source is used to reduce emission. Experimental investigation gave output that biodiesel-diesel-camphor blend can be used in compression ignition in without any changes in engine’s working parameters and emission is reduced using a photocatalyst titanium dioxide in exhaust gas track.
