Performance Evaluation of the Combination of Bio Fuels Derived From Waste Cooked Oil and Pongamia Pinnata 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.
