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...
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...
If you have accidentally poured AdBlue® into your diesel tank, or just as likely, accidentally poured diesel into your AdBlue® tank. What should we do at this time? Luckily AdBlue® tanks are clearly marked with a BLUE cap, but accidents happen and if you do find yourself in the worst case scenario follow these tips. First thing - Don't start the engine If you turn the ignition on and s...
1. The urea content directly effect the catalytic efficiency and freezing point of AdBlue®. In SCR system, the urea content in AdBlue® is one of the key factors. Too high or too low urea content can't improve the conversion efficiency of NOx, and it will cause ammonia to escape. At the same time, the urea content directly affects the catalytic efficiency of NOx and the freezing point of Ad...
Refilling the AdBlue tank is not a do-it-yourself task. Although it is possible to purchase the urea solution at the retailer, it is generally available only through a dealership or service shop. The systems are designed with a capacity of several gallons which transforms into several thousands of miles. Under normal vehicle operating conditions, the AdBlue® tank needs to be refilled only duri...
The size of the AdBlue ® tank fitted to your vehicle will depend on the brand and model of your vehicle. Therefore the difference between top-ups will vary. In addition, many factors such as vehicle load, driving style, climatic conditions, traffic flow and road condition can affect the consumption of AdBlue ®. Like fuel, the more economically of your vehicle, the less AdBlue&nbs...
At present, two technical solutions are adopted to solve the problem of diesel exhaust emissions. One is SCR technology , another is EGR+DPF. Principle of EGR (Exhaust Gas Recirculation): The technology introduces engine exhaust gas into the intake pipe to reduces the oxygen concentration entering the cylinder and controls the combustion speed as well as lowers the combustion t...
