What is the urea mark of automobile instrument?

The sign of urea lamp has different forms. The average car is a sign that the bottle is pouring water; Large trucks are marked with the charging mode of electric piles (Ad blue).

Liquid used in SCR technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. Its components are 32.5% high purity urea and 67.5% deionized water. When this light is on, it means that the urea solution is insufficient. Please add it.

Origin and present situation:

Because the environmental protection departments of various countries have proposed to further reduce the nitrogen oxide pollutants emitted by diesel engines. Commonly known as Euro IV standard in China. Engine manufacturers began to use SCR technology (selective catalytic reduction technology) to meet the requirements of environmental protection departments.

Diesel engine exhaust treatment liquid (commonly known as automobile urea, automobile urea and automobile environmental protection urea) is a consumable that must be used in SCR technology. In fact, in Europe, this policy was implemented in 2006. The European diesel tail gas treatment liquid is called Adblue. The main representatives are BP and so on.

In the United States, since 20 10, with the implementation of EPA20 10 standard, the application and implementation of this product have been comprehensively strengthened. In the United States, diesel exhaust gas treatment liquid is called DEF (Diesel Exhaust Gas Liquid). The main representatives are BlueDEF and so on.

This product has two major certifications in the world, one is AdBlue certification of German Automobile Industry Association (VDA), and the other is DEF certification of API gravity (API).
