عنوان المقالة:11. An Experimental Study on Combine Effect of Exhaust Gas Recirculation (EGR) and Inlet Air Temperature on Emissions of Diesel Engine in Iraq with Using Daura Fuel, Australian Journal of Basic and Applied Sciences, 8(16) October 2014.
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 30C˚of intake air temperature , However. In this study it was
concluded that using EGR with rate 15% and uniform inlet temperature (30 C º)
reduced the NOX47.4%
