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.
What is DEF?
Diesel Exhaust Fluid, or DEF, is a high-purity urea-based solution designed to reduce NOx emissions in new diesel vehicles. NOx is a pollutant that contributes to the formation of smog and acid rain, which can damage our health and the environment.
DEF is designed to be used in diesel engines equipped with SCR technology. When DEF is injected into the exhaust system of an SCR-equipped diesel engine, it reacts with a catalyst to break down NOx molecules into harmless nitrogen and water.
DEF is an odorless, colorless, non-flammable and nontoxic solution that is harmless to people, equipment and the
environment.High-purity DEF is increasingly available across the U.S. from companies like Airgas, which supplies ultra-pure Airgas AiRx DEF.
SCR Technology
Selective Catalytic Reduction, or SCR, is the leading emissions control technology available for diesel engines. SCR systems use a catalytic converter, with the addition of DEF, to break down NOx emissions.
DEF is not a fuel additive, but a completely separate solution that resides in its own tank. First, it is injected directly into
the exhaust stream, where it is then vaporized by a catalyst, forming ammonia. From there, the ammonia works in conjunction with the SCR catalyst to convert harmful NOx emissions into harmless nitrogen and water.
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.
