Consumables Used in SCR Technology
Diesel Exhaust Treatment Fluid (commonly known in China as: automotive urea, automotive urea, automotive eco-friendly urea), is a consumable that must be used in SCR technology.
Basic Information
Chinese Name Diesel Exhaust Treatment Fluid
Foreign Name adblue
Generic Name Automotive Urea Automotive Urea Water
Introduction
SCR system includes a urea tank (loaded with Diesel Exhaust Treatment Fluid), and a SCR catalytic reaction tank.The SCR system operates as follows: when the exhaust is found When found in the exhaust pipe nitrogen oxides, urea tank automatically spray diesel exhaust treatment fluid, diesel exhaust treatment fluid and nitrogen oxides in the SCR catalytic reaction tank in the redox reaction occurs, the generation of non-polluting nitrogen gas and water vapor discharge. As the environmental protection departments of various countries proposed to further reduce diesel emissions of nitrogen oxide pollutants. Domestic commonly known as Euro IV standards.
Engine manufacturers began to use SCR technology (Selective Catalytic Reduction Technology selective catalytic reduction technology) to meet the requirements of the environmental protection department.
If the diesel exhaust treatment fluid is not loaded, or the purity is not enough, or the quality is shoddy, it will happen that the engine of the vehicle automatically slows down. At the same time, shoddy quality diesel exhaust treatment fluid will contaminate the catalyst in the SCR catalytic reaction tank, resulting in serious consequences.
In fact, in Europe, this policy has been implemented since 2006. The European diesel exhaust treatment fluid is called Adblue. the main representatives are BP and so on.
In the United States, after 2009 will increase the implementation of the United States diesel exhaust treatment fluid called DEF (Diesel Exhaust Fluid). The main representatives are BlueDEF and so on.
In the country, the pilot has begun. For the production of diesel exhaust treatment fluid is still an emerging industry.
