Performance Evaluation Of The Combination Of Bio Fuels Derived From Waste Cooked Oil And PongamiaPinnata Oil

Abstract

Almost all countries are dependent on petroleum fuel to fulfill  their energy requirements Increase in energy  demand due to  growth  in  population has affected  the  underground fossil  fuel  resources .  In   order  to  counter  this  problem, researchers  are  looking  for  alternative  sources of  energy. Biodiesel  is  one of  the potential  alternatives  to  petroleum dies el,  as  its   properties  are   very  comparable   to   dies el. Moreover, biodiesel   is   mainly    derived   from   renewable feeds tocks like edible, non -edible oils or animal fats.  In recent decade, the main focus it to prepare biodiesel from edible oils like   cottonseed oil, sunflower oil, coconut oil. Producing biodiesel from edible oils may leave negative effect on agriculture in terms of scarcity of food crops so non-edible oils are preferred for production of biodiesel. The  main advantages of using biodiesel are it’s portability, being readily available, better combustion   efficiency, lower sulphur content,  higher cetane   number,   higher   bio degradability, domestic origin,  higher flash point and improved  lubrication property.   Researchers  have  found  that  with  us e  of biodiesel nitrogen oxides (NOX)  emission  increases whereas hydrocarbon (HC),  carbon monoxide   (CO),  and particulate matter emissions (PM) decrease in  comparison to dies el fuel.  The present paper, therefore, focuses on the emissions from biodiesel fuelled dies el engine operation.
