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 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 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...
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...
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...
As the world's largest motor vehicle market, China's automotive AdBlue® market is rapidly opening. Relevant professionals predict that heavy diesel vehicles equipped with SCR systems will grow at least 500,000 vehicles a year, reaching 2.25 million by 2017. According to the diesel vehicle output calculation, it is expected that by the end of 2018, China's AdBlue® market capacity will reach...
In order to avoid contamination of automotive urea solutions and corrosion of containers, pipes, valves, connectors, gaskets, etc., it is necessary to ensure that the urea solution of the vehicle is compatible with the material in direct contact at all stages of handling, transportation, storage and sampling. Highly alloyed austenitic Cr-Ni-steels and Cr-Ni-Mo-steels, for example in accordance wit...
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,...
