Automobile urea solution is an essential additive for SCR system of diesel engine. It is selectively catalyzed and reduced by NOX products to convert it into nitrogen, oxygen and water to reducing the emission of nitrogen oxides.
As the environmental protection departments of various countries propose to further reduce the nitrogen oxides emitted by diesel engines. Domestically known as the European IV standard.
Engine manufacturers began to use SCR technology (Selective Catalytic Reduction Technology) to meet the requirements of environmental protection departments. Targeted research on reducing agents required for SCR emission after-treatment technology has led to the creation of high-quality standard AdBlue for vehicles.
Automotive Grade Urea
Automotive Grade Urea is a special, uncoated version of highest purity. It is a main component of urea solutions like Diesel
Exhaust Fluid or AUS40/45 which are used within SCR-systems for the reason of NOx reduction.
It is the only type of Urea that meets the ISO 22241 specification and the only suitable Urea for the production of DEF/AUS32/ARLA32 solutions. For meeting the ISO22241 the Urea needs to be of highest purity/quality.
