Bio diesel production by using Jatropha: the fuel for future

ABSTRACTPresently biodiesel is widely used globally due to high scarcity of petroleum products and being a renewable fuel which can be used with the current fuelling infrastructure in an unmodified diesel engine. It is a harmless, recyclable, and ecofriendly fuel (reduces air pollutions such as dust, particulates, carbon monoxide, hydrocarbons, and oxides of sulphur and air toxics). In India, the favourable conditions for the growth of Jatropha exist. Its use a biofuel is going to prove very beneficial for the Indian as well as the world market with the increase in fossil fuel’s demand and its reducing availability. The only drawback in using jatropha oil as a fuel is that the NOxemission is more than that of petroleum diesel. This paper deals with the implementation of exhaust gas recirculation to reduce the emission of NOxand to study its characteristics with respect to the performance of the engine.Abbreviations:HSD: high-speed diesel; BD: biodiesel; EGR: exhaust gas recirculation; NOx: nitrous oxide; CO: carbon mono oxide; NaOH: sodium hydroxide; RCAC: Rural Action Community Action Center
