OBJECTIVE OF PROJECT
Study of reduction in NOx emission due to exhaust gas recirculation.
Effect of EGR on emission of other exhaust gases.
Fabrication of EGR valve
Study of performance characteristics after installing EGR.
HOW EGR REDUCES NOx
Increased ignition delay.
Increased Heat Capacity.
Dilution of intake charge with inert gas.
Reduced Combustion Temperature.
