AN EXPERIMENTAL ANALYSIS ON BIODIESEL PRODUCTION FROM CEDAR WOOD OIL AND ITS PERFORMANCE AND EMISSION TESTING ON A DIESEL ENGINE

Abstract

Non-edible oils have been searched to make biodiesel to substitute conventional diesel fuel as these are depleting in a very fast manner. Cedar Wood (Cedrus deodara) is a tree available in different parts of world like India, Nepal. Methyl ester of (Cedar Wood) is prepared by process known as trans esterification. Transesterification shows improvements in fuel properties and Biodiesel parameters like viscosity, density, calorific value are according to EN and ASTM standards. For finding the fatty acid profile of biodiesel Gas Chromatography (GC) technique is used. Six fatty acids were identified by oil characterization. Various proportions of methyl ester and diesel were prepared for using in Four stroke, single cylinder diesel engine. Diesel and Cedrus Oil methyl ester (10%,20%) fuel blends were used for emission testing and engine performance. Different tests were performed for engine operation and certain parameters like, brake thermal efficiency, brake mean effective pressure, brake specific energy consumption and emissions of exhaust like carbon monoxide(CO),hydrocarbon(HC) and NOx produced by engine were recorded.. The results obtained show that various blends like B10 and B20 of Cedar wood oil biodiesel with diesel can be used as an alternative fuel in C.I engine.
