The SCR exhaust after-treatment of the diesel engine is effective in controlling emissions of carbon monoxide (CO), hydrocarbons (HC) and particles (PM) in the exhaust gas to meeting the requirements of the regulations. Then the high content of nitrogen oxides (NOX) in the exhaust exhaust of the engine is treated by a special on-board aftertreatment system. At present, a variety of diesel exh...
The need to control toxic emissions from diesel combustion engines is ever-increasing. AdBlue® are being developed to manage the output of poisonous gas like nitrogen oxide(NOx) from engine exhaust systems. Selective Catalytic Reduction(SCR) is a method of controlling nitrogen oxide emissions. This process requires diesel exhaust fluid, namely AdBlue®, to be injected into the exhaust pipe ...
Exhaust gas treatment fluid, commonly known as automotive urea fluid, is a consumable that must be used in SCR technology and is mainly used for exhaust gas treatment of diesel engines. With the policy for energy conservation and emission reduction, most light trucks on the market are now equipped with urea tanks, but many people cannot tell well what is the difference between automot...
urea aqueous solution for vehicle How do you store AdBlue? AdBlue should ideally be stored within a temperature range between 0 and 30°C, and kept protected from direct sunlight. It should be properly sealed when it is not being used. It is possible for AdBlue to freeze at -11°C, so it is important that you use a storage area that is not below this temperature. Can AdBlue be stored once opened? ON...
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...
