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...
Heavy goods vehicles – trucks, coaches and buses have been using SCR technology and AdBlue since 2004. For example, Mercedes and Volkswagen. The latest Euro VI emissions regulations from the European Commission has really driven an explosion in SCR technology from the passenger car perspective in Europe. The Euro VI regs introduced in 2014/15 demanded nitrogen oxides emissions should be reduced by...
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...
The qualified AdBlue® is a high-purity transparent liquid composed of 32.5% high-purity urea and 67.5% deionized water. It has a light ammonia smell and is suitable for all Euro IV and Euro V emission diesel engine with SCR system. The fertilizer urea prilled will cause the catalyst poisoning and damage parts of SCR tail gas processors by its excessive biurea , mechanical impurities ...
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...
The SCR/Urea Solution is aimed to apply the stricter emission regulations for Vehicles or heavy machineries with diesel engines. The particulate matter and nitric oxide are the main sources of pollution coming out from the exhaust system, and there are two main after treatment technics worldwide, the SCR and the EGR+DEF. The SCR is mainly used in Euro and Asia, but also the US since 2010. As...
