摘要：In various countries around the world, the emissions of NOX from petrol/gasoline and diesel engine vehicles are restricted by legislation. NOX is produced in the combustion chamber of engines at high temperatures and high pressure. One of the most promising technology for effective control of NOX emissions is Exhaust Gas Recirculation (EGR) and now most modern engines require exhaust gas recirculation to meet emission standards. EGR lowers the presence of oxygen concentration and burn temperature in the combustion chamber and hence controls the NOx. The experimentation was carried out on a 5.2 kW of single cylinder four stroke direct injection diesel engines in computerized mode to investigate the performance, emissions and combustion parameters at different EGR ratios (10, 20 and 30%). From the results, O2, NOX and exhaust temperatures are found to be reduced whereas HC and CO emissions are increased as the EGR concentration increases.
