Preparation of Biodiesel from Castor Oil and Performance Evaluation in VCR Engine

Abstract

Biodiesel can be used as Alternative fuel and acts as Renewable energy source. Rapid growth in industrialization of developing countries is resulting in increasing demand for new and eco-friendly energy sources. In this present research biodiesel was prepared from Castor oil by esterification and Transesterification process. The castor oil biodiesel produced was blended with diesel to obtain B10.Performance evaluation was carried out in VCR engine and emission testing was done by Gas analyzer to know the percentage of CO,HC, NOX and comparison study was done with diesel and biodiesel blend. In this study it was found that NOx emission rate of biodiesel blend increases while percentage of CO, HC increases. Also various performance indicators such as break mean effective pressure, specific fuel consumption; break thermal efficiency was plotted with respect to variation of load by using VCR engine.
