Abstract:Concern of environmental pollution and energy crisis all over the world have caused the research attention on reduction of diesel engine exhaust emissions and saving of energy simultaneously. Better fuel economy and higher power with lower maintenance cost has increased the popularity of diesel engine vehicles. Diesel engines are used for bulk movement of goods, powering stationary/mobile equipment, and to generate electricity more economically than any other device in this size range. As we know that the diesel engine are known for their high NOX formation and Exhaust Gas Recirculation (EGR) is being used widely to reduce and control the oxides of nitrogen (NOX) emission from diesel engines. EGR controls the NOX because it lowers oxygen concentration and flame temperature of the working fluid in the combustion chamber. By using heating intake air it was concluded that decreasing the CO with 12% and the HC with 35% with 30Cof intake air temperature , However. In this study it was concluded that using EGR with rate 15% and uniform inlet temperature (30 C ) reduced the NOX47.4%
