Performance Evaluation of a Single Cylinder Compression Ignition Engine using Diesel and Bio-Diesel

The world is getting modernized and industrialized day by day. The transportation sector is one of the most fossil energy consuming sectors and the combustion of fossil fuels contributes to increased greenhouse gas concentrations in the atmosphere. The Depletion of the petroleum reservoir on the earth increases concerns about the environment which leads to the quest for fuels which are eco-friendly and safe for human beings. The use of bio-fuels helps to stabilize the greenhouse gas levels in the atmosphere also the dependency of fossil fuels could be deceased. This situation leads to seek an alternative fuel for diesel engine. Biodiesel is an alternative fuel for diesel engine. The esters of vegetables oil animal fats are known as Biodiesel. Effective utilization of fuel at various engine operating conditions, without adversely affecting the engine performance, it is economically possible to reduce exhaust emissions from old engines also, rather than going for engine modifications. In this paper, the biodiesel produced from the seeds of the Jatropha plant is used to evaluate the Performance of a single cylinder C.I. engine performance.
