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...
It is a particularly big misunderstanding, adding urea for vehicles will not increase fuel consumption. First understand the working principle of post-treatment. Basically, the exhaust gas comes out of the turbine and enters the exhaust pipe. A urea metering injection device is installed on the exhaust pipe, and the urea solution is sprayed. The urea solution and the nitrogen oxides in the ex...
AdBlue(Diesel Exhaust Fluid) is non-toxic. However, some processing or modification aids, such as fillers, stabilizing agents or pigments, are used in the production of such plastic barrels. These material components contain harmful substances. Therefore, such plastic barrels cannot be used as storage containers or after use. are other items. Vehicle urea is a liquid used in SCR technology to redu...
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...
The urea solution for vehicles was first used in Europe, called AdBlue®, and in North America called DEF (Diesel Exhaust Fluid). It should be noted that there are very few companies certified by AdBlue® and DEF. Simply put, the quality of the production company with the AdBlue® trademark is more guaranteed. AdBlue® is a urea solution made of 32.5% high-purity urea and purified wate...
AdBlue® is a chemical liquid product that is non-toxic, odorless, colorless, safe for the surroundings and environmentally friendly. High quality and purity of the product are required both at the production stage, as well as during transport and storage. All surfaces in direct contact with AdBlue® should be free from foreign substances (oil, fuel, detergent) and solid particles..Injected ...
Urea solution for vehicles is an environmentally friendly product, and it is used on trucks to control exhaust pollution. It can be said that users have contributed to environmental protection, but it has to be said that urea solution for vehicles has also brought a lot of trouble to users and increased costs. , The failure rate is high, and it crystallizes at every turn. Many users also complain ...
The urea solution for vehicles must not be used after the expiration date. The concentration of the expired urea solution for vehicles is already impure, and it is likely to have exceeded 32.5%. The content of biuret has also increased, which will reduce the reduction of nitrogen oxides. deal with. Under the correct storage method, the shelf life of urea for vehicles is as long as 2 years, so norm...
