It to be able to be seeing of the circumstantial intelligence by clicking the corner name. Continuous Regenerating Diesel Particulate Defuser Particulate matter (PM) collected by the filter is burned efficiently and the filter is repeatedly regenerated, enabling continuous after-combustion treatment of emissions. Next-Generation Urea-Selective Catalytic Reduction Using ammonia generated by spraying urea water on emission gases, this after-combustion treatment technology relies on the reaction between ammonia and nitrogen oxides (NOx), which results in harmless water and nitrogen.
