AdBlue DEF is a consumable that must be used in SCR technology. SCR technology uses a catalyst system can effectively reduced the emission of nitrogen oxides and solid particles produced by diesel engines into nitrogen and water.The main components of the SCR system include the catalyst, the AdBlue® injection unit, the urea tank and the AdBlue® dose controller. Process of SCR technol...
AdBlue Aqueous urea solution is alkaline with feature of non-toxic , non-pollutiing and non-flammable. AdBlue® Aqueous urea solution has special requirements for storage materials and storage conditions ,because of its alkaline characteristics. (1) The effect of storage temperature on AdBlue DEF: AdBlue® requires a storage temperature of about -5 to 25 ℃, it should be avoid sunlight and hi...
Misunderstanding 1 :Using agricultural urea instead of industrial urea for AdBlue® AdBlue® has strict ratio requirements which are basically composed of high-purity urea and deionized water and the ratio is strictly controlled. One of the criteria for quality is the control of impurities. There are many impurities such as particulate matter, metal ions and minerals in agricultural urea and...

One aspect of a vehicle with SCR system is the need for replenishing Diesel Exhaust Fluid (DEF) on a periodic basis. DEF is carried in an onboard tank which must be periodically replenished by the operator based on vehicle operation. For light-duty vehicles, DEF refill intervals typically occur around the time of a recommended oil change, while DEF replenishment for heavy-duty vehicles and off-roa...
AdBlue® for vehicles is developed as the regulations for heavy-duty diesel vehicles are becoming more stringent. Particulate matter (PM) and nitrogen oxides (NOX) in diesel exhaust are the two main sources of vehicle exhaust pollution. For nitrogen oxides, the main exhaust aftertreatment technologies used in Europe and America are SCR and EGR+DPF, of which Europe and Japan is dominated by SCR,...
There are three reasons for the blockage of urea crystallization in AdBlue® production machine. Here are three main reasons for the blockage ; I. Atomization effect or failure of the nozzle SCR system can be divided into two types: air-free type and air-assisted type. Generally, the working pressure of air-assisted urea injection is relatively high, so it may occur that the nozzle valve needle...
It depends on many factors, includes the diesel engine size, driver, DEF system condition, presence of NOx in the exhaust stream. Typically, manufacturers refer to DEF consumption as a percentage or fuel consumption. This can vary from as low as 2% to as high as 10%. So if your engine consumes 100 gallons of fuel, for a 10% DEF consumption, it would have used 10 gallons of diesel exhaust fluid def...
