Selective Catalytic Reduction (SCR) System and Adapting on the Vehicles

More challenging controls are being carried out every day and limitations are brought to reduce the negative effects of the exhaust gases generated by the number of vehicles that is increasing in parallel with world population on the environment and human health. because of this reason, automotive companies need to develop new technologies to reduce harmful gas emissions. in this research, negative effects of harmful exhaust gases on human health and environment, new technologies and studies that automotive manufacturers are performing to reduce these emissions have been discussed. selective catalytic reduction (scr) method which is the most advanced technology applied to limit the amount of harmful nitrogen oxides in diesel vehicles has been analyzed, required conditions for minimizing the amount of nitrogen oxide and the chemical reactions are explained. also the advantages and disadvantages of the method compared to other technologies have been examined and criticalities in adaptation on the vehicles have been discussed.
