The enormous volume of petroleum fuel burnt has a direct correlation to both hazardous exhaust emissions for human health and global warming. At first, biodiesel fuels were suggested as a workable substitute fuel to cope with these problems. This viewpoint is supported by the many published studies in the field that study looks at how Exhaust gas recirculation (EGR) is one of the effective methods to control the combustion and emissions of a diesel engine. In EGR method, some portion of exhaust gas was recirculated into the inlet manifold to mix with intake air and then it enters into the cylinder. We deduced the most of the research from it by looking at certain research. The use of Exhaust gas recirculation (EGR) results in increases in carbon dioxide (co2), carbon monoxide (co) and brake specific fuel consumption (BSFC). It lowers the temperature of exhaust gases, NOx concentrations, brake thermal efficiency and the amount of smoke. The current review research concluded categorically that the degraded engine performance, combustion, and emission characteristics of Exhaust gas recirculation (EGR) on diesel engine with diesel fuel.
