urea aqueous solution for vehicle How do you store AdBlue? AdBlue should ideally be stored within a temperature range between 0 and 30°C, and kept protected from direct sunlight. It should be properly sealed when it is not being used. It is possible for AdBlue to freeze at -11°C, so it is important that you use a storage area that is not below this temperature. Can AdBlue be stored once opened? ON...
DIN 70070 is one of the quality standard of AdBlue which refer to Diesel engines - NOx-Reduction agent AUS 32 - Quality requirements from German-german Institute for Standardization (Called as DE-DIN). It is an odorless, colorless transparent solution synthesized from 32.5% industrial urea and 67.5% deionized water. Used in modern exhaust pollution control systems, referred to as SCR systems (sele...
First of all, what is AdBlue? It is diesel exhaust treatment liquid, also known as automobile environmental urea, is made of water and urea, can effectively reduce the content of nitrogen and oxygen compounds in automobile exhaust, it reacts with the NOx from the exhaust gases, turning NOx into Water and Nitrogen. The AdBlue light of your car will be on, when the tank is almost empty, ...
According to the "Letter to the European Commission's Euro 7 Emissions Industry", it can be known that the Euro 7 emission standards require that the carbon monoxide emissions of tail gas be reduced from the current 500-1000 mg/km to 100-300 mg/km, while the nitrogen oxide emissions must be reduced to 30mg/km. Among them, the Euro VII emission proposal will force traditional fuel vehicles to be eq...
AdBlue is also known as diesel exhaust fluid, but it is commonly mistaken as a fuel additive. It should never be mixed with diesel, AdBlue has its own tank and is stored completely separately to the vehicles’ fuel tank. If you put diesel fuel into the AdBlue tank, below actions should be taken immediately to avoid some serious damage to the SCR ( Selective Catalytic Reduction). Step 1: Do not star...
The SCR scheme has obvious advantages in the national IV diesel vehicle exhaust emission treatment system and Diesel Exhaust Fluid for vehicles is a necessary additive for the SCR scheme. With the gradual implementation of the National IV emission standards for diesel vehicles in various cities, the demand for Diesel Exhaust Fluid may be blowing out. The SCR system includes a DEF tank (l...
Domestic AdBlue® is mainly purified from industrial urea, and its main principles are: 1) At a temperature of 70-75°C, urea is hydrolyzed in aqueous solution. 2) When the temperature is below 30°C, urea crystallizes out from the aqueous solution again. 3) With each hydrolysis and crystallization, its purity will be greatly improved. Generally, industrial grade urea is used for hydrolysis and c...
It's difficult to determine the exact number of trucks that require AdBlue® in the world. AdBlue® is commonly used in diesel engines equipped with Selective Catalytic Reduction (SCR) systems to reduce nitrogen oxide (NOx) emissions. These systems are widely used in heavy-duty trucks and buses in Europe, but are less common in other parts of the world. It's estimated that there are over 100...
