Experimental Investigation of Engine Performance and Exhaust Emissions of Produced Biodiesel from Waste Cooking Oil

Abstract

Availability of petroleum and environmental concern fuels has caused attention in the look for internal combustion engine alternative fuels. Various researchers have tried on many alternate fuels. Literature review depicts bio-diesel as most promising fuel for diesel engine. Pure biodiesel was produced from wasted cooking oil during trans-esterification, and by further processes, biodiesel is prepared. The properties of these were compared favorably with the characteristics essential for internal combustion engine fuels particularly diesel engine. The results obtained from testing demonstrates that without changing any component of the diesel engine, for all blend conditions engine performance is similar to the results with standard diesel. Moreover, the B10, B5 blend fuels (comprise 10%, 5% biodiesel respectively) led to reasonable emissions at variable load. These experimental results compared with standard diesel which depicts significant reductions in CO, and NOx, with the increase of unburned HC. As biodiesel is sulphur free fuel, significant reductions in CO2 is observed.
