Sustainable Biodiesel from Temple Waste Oil: A Study on Conversion Process, Engine Performance and Emission Analysis

Abstract

Inflation in fuel prices and unprecedented shortage of its supply has promoted the interest in development of the alternative sources for petroleum fuels. The present paper discusses with the various phases of production of bio-diesel from temple waste oil. The phases of collection of waste oil from temple, pre-treatment and transesterification are discussed. Investigations were carried out to study the performance, emission and combustion characteristics of temple waste oil. The results were compared with diesel fuel, and the selected temple waste oil fuel blends (10%, 20%, 30% and 100%). The engine performance parameters such as specific fuel consumption, Brake Thermal Efficiency and Exhaust Emission (CO, SOx, HC, and NOx) were recorded. The exhaust gas emissions are reduced with increase in biodiesel concentration. The experimental results proved that the use of biodiesel in compression ignition engine is a viable alternative to diesel. From the comparison of results, it is inferred that the engine performance is improved with significant reduction in emissions for the chosen oil without any engine modification.
