Effect of Exhaust Gas Recirculation (EGR) On Engine Performance and Emission on C I Engine
Bharat N kharad , Prof. K. B. Bokankar
An internal combustion engine is having a high efficiency, high power with lower maintenance cost. Because of that Internal Combustion Engines are increased worldwide. It is the main power source for the automobile vehicles. Now a present emission norm becomes strict for any I.C. Engine. The main pollutant are CO, CO2, HC, NOx, PM, soot, etc from which NOx are one of the most harmful component. It affects the human and other living organisms. It is possible to limit the NOx in the atmosphere by various methods like exhaust gas recirculation (EGR), catalyst or SCR and water injection. The aim of this work is to find the effect of exhaust gas recirculation (EGR) to reduce the NOx emission from the I. C. Engine with measuring the all pollutants for different EGR with different load condition and find the optimum condition of emission and performance. It is found that adding EGR to the fresh air it is beneficial to reduce the NOx emission. Reductions in NOx emission are achieved by previous research with 5% to 30% EGR. However, EGR has other effects on combustion and emission production that are increase of intake charge temperature, delay in heat release, decrease of peak cylinder temperature and decrease in O2 concentration in cylinder charge and decrease the air-fuel ratio.
