INVESTIGATION ON EFFECT OF EGR ON CI ENGINE FUELLED WITH KARANJA BIODIESEL :A REVIEW

Internal combustion engine, mainly diesel engine play impo rtant role for transportation purpose, off road heavy duty works, in passenger vehicles and mechanized agricultural works. looking towards continuous decrements of fossil fuels and stringent emission norms lead to have use of alternate fuel so as to contr ol emission due to stringent emission norms as well to enhance life and performance of engine. Use of biodiesel is now developing interest towards use of alternative fuel. As in India biodiesel production mainly from jatropha seed,karanja plant, neem oil e tc.Karanja oil properties is same as that of diesel recommended that transesterification process need to followed by proper catalyst. By literature survey it is found that Biodiesel blend of karanja oil with diesel say KBD30+EGR10% shows good properties as thermal efficiency is get improves as well NO emission get reduced by 25% ,HC by 15% and significant reduction in CO too [7]. Main reason behind EGR is to reduced cylinder pressure and temperature so as to reduce NO emission
