PERFORMANCE AND EMISSION CHARACTERISTICS OF DIESELENGINE USING RAPESEED AND PONGAMIA OIL AS BIOFUELS. NALLUSAMY, F. FREDRICK GNANARAJ AND D.A. VINOTHAbstract In the present global scenario, fossil fuels are exhausting in fast manner and hence we are in need of research for alternate fuels where a huge demand of fuel in transport sector. The main objectiveof this research work is to analyse and compare the performance and emission characteristics ofrapeseed and pongamia biofuel in diesel engine. The main problem occurs in biodiesel is its higherviscosity than the regular diesel. Experimental results revealed that the biofuel and bio lubricantbased on rapeseed oil exhibited better performance with significant reduction in particulate, COand NOx emissions under similar operating conditions and in terms of wear rate. Also it was foundthat, all performance characteristics like BSFC, BTE, ME and BP were better for rapeseed blends.It was observed that biodiesel will replace diesel as a source of fuel in near future and thus plantof biofuel in long run may have a positive impact on engine life.
