In the present investigation, the experimental work was carried out to study the influence of the exhaust gas recirculation on the performance and emission characteristics of the biodiesel fuelled diesel engine and compared with those of diesel by recirculation of the exhaust gas at the inlet valve. The experimental works were conducted by varying the exhaust gas flow rate in terms of percentage followed by 10 %, 20% and 30% for B20 biodiesel and neat diesel. The performance and emission characteristics of the engine were discussed for both the diesel and B20 Calophyllum-Inophyllum biodiesel fuels. The results were reveled that the IP, ME, brake thermal efficiency, indicated thermal efficiency decreases for B20 Calophyllum-Inophyllum biodiesel than compared to diesel fuel and the emissions of CO, CO2, NOx and HC were found to be lower with B20 biodiesel for without EGR. However, with the increase of EGR flow rates resulted in considerable rise in CO, CO2 and HC emissions for both diesel fuel and B20 biodiesel whereas NOx emissions simultaneously reduces in larger quantity. Therefore EGR method is the effective way to reduce the NOx emission which is harmful to the environment.
