SCR scheme on the two sides of Ⅳ has obvious advantages in processing system in diesel exhaust emissions, and automotive urea is necessary additives of SCR scheme. As the diesel countries four emission standards were gradually from city to city, vehicle demand urea or blowout.
Due to the environmental protection department put forward further reduce diesel engine exhaust emissions of nitrogen oxides pollutants. Commonly known as euro IV standard in China.
Engine manufacturers started using SCR Technology (Selective Catalytic Reduction Technology of Selective Catalytic Reduction Technology) to meet the requirements of the environmental protection department.
Diesel engine tail gas treatment fluid (urea, urea, commonly known as: automobile car car environmental urea), is the SCR technology must be used in consumables.
Why does a car need to be reloaded with urea?
The SCR system comprises a urea tank (a diesel exhaust treatment solution) and a SCR catalytic tank. SCR system operation process is: if I found you have nox in the exhaust pipe, urea can automatic overflowing diesel exhaust treatment fluid, diesel exhaust treatment fluid and nitrogen oxides in the SCR catalytic reaction tank REDOX reaction, generating no pollution of nitrogen and water vapor.
If the diesel exhaust treatment solution is not loaded, or the purity is not enough, or the quality is shoddy, the vehicle engine will automatically decelerate. At the same time, the quality of shoddy diesel engine exhaust treatment can contaminate the catalyst in the SCR catalytic reaction tank, causing serious consequences.
In fact, in Europe, this policy was implemented in 2006. The European diesel exhaust treatment solution is called Adblue. The main representative is BP and so on.
In the United States, in 2010, with the implementation of the EPA2010 standard, the application of this product has been greatly enhanced. In the United States, Diesel Exhaust treatment Fluid is called "DEF". The main representative is BlueDEF and so on.
At home, the LANKX vehicle of jiangsu orchid trusted environmental protection technology co., LTD. Has obtained a number of qualified and honorary certificates.
