Studying The Application Of The Refrigerated EGR Technology On A Diesel Engine And Its Impact On The Pollutants Produced In Different Working Conditions

In this study circuit is designed and installed to measur the pollutants from the diesel engine in two stages at three speeds 1100, 1500, 1800rpm. When recycling rates range (0-70)% for no load. for load experiments, we measured the pollutants at the previous three speeds at 50% load values and at full load. We were able to apply the load through a mechanism to apply the friction torque on a roller that was installed on the engine axis. We finally found that pollutants of all kinds are increasing by increasing the speed of circulation, as well as by increasing the applied load, and that the emissions of nitrogen oxides decrease the increase in the proportion of recycled gases, while the emissions of the remaining pollutants increase.
