Abstract: Automobile emission is one of the major problem in environment. Engine emits the Carbon monoxide (CO), Hydrocarbon (HC), Nitrogen oxides (NOX), and smoke density etc. in this the Nitrogen oxides (NOX) emission leads to dangerous effects on environment. Therefore we will study on performance and emission characteristics of diesel engine and diesel fuel using exhaust gas recirculation with the help of EGR and control the Nitrogen oxides (NOX) emission from diesel engine and also increase performance of diesel engine. For the better result, optimum condition of 15 % EGR is achieved.20 % bio fuel will reduce the NOx concentration by 25 %. A turbocharged internal combustion engine assembly with exhaust gas recirculation (EGR) includes an air compressor driven by an exhaust turbine, an EGR line that diverts Exhaust gases from an exhaust line leading from the engine to an air intake line leading to the engine from the compressor, and a combustion bypass line that conveys Compressed air from the compressor to the exhaust turbine without combustion. Diesel engines, a special type of internal combustion engine, use heat of compression, rather than electric spark, to ignite hydrocarbon fuels injected into the combustion chamber. Diesel engines have high thermal efficiency and thus, high fuel efficiency. They are widely used in commerce prompting continuous improvement in diesel engines and fuels. Concern for health effects from exposure to diesel exhaust arose in the mid-1900s and stimulated development of emissions regulations and research to improve the technology and characterize potential health hazards.
