Biodiesel is obtained from vegetable oils throughout transesterification process. There are many advantages of biodiesel but it leads to high NOx emission. In order to reduce NOx emission from the engine, it is necessary to keep max out combustion temperature under control. EGR technique is used to reduce NOx emission as it enables lesser flame temperature and oxygen concentration in combustion chamber. At near emission norms becomes harsh for any I.C. Engine. The chief pollutant are NOx, PM, CO, HC, soot, etc from which NOx are very harmfull component. It is possible to limit the negative effect of NOx on the environment by a variety of methods such as catalyst, water injection and exhaust gas recirculation. The purpose of this work is to study the effect of exhaust gas recirculation (EGR) on the NOx emission from engine exhaust. Cooled exhaust gas recirculation (EGR) is a general way to control the NOx generation. It was found that adding exhaust gas to the fresh air charge will advantageous to reduce the NOx emission considerably. Reductions in NOx emission are achieved by earlier investigators with 10% to 30% EGR. However, EGR has other effects on emission production and combustion that are decrease in peak temperature, delay in heat release, and Oxygen concentration in cylinder charge and reduce the air-fuel ratio.
