How to use car urea, how to add car urea

Vehicle urea is a must-have product for heavy-duty diesel vehicles to meet the national IV emission standard, which is directly filled into the urea tank for use, and its urea concentration is a urea aqueous solution with ultrapure water as the solvent, and the raw materials are urea crystals and ultrapure water. In order for diesel vehicles such as heavy-duty trucks and buses to meet the national IV emission standards, a suitable SCR system must be selected in the exhaust gas treatment, and this system must use urea solution to treat the nitrogen oxides in the exhaust gas. Therefore, vehicle urea solution has become a necessary product for heavy-duty trucks and buses to meet the national IV emission standard.

At present, the well-known domestic brands are Sinopec Yuetai Hailong and Meifeng Jialan.

Vehicle urea is mainly used in diesel vehicles to deal with car exhaust, and the cars above the fourth car have a urea tank, and the vehicle urea can be poured directly into the urea tank!

When nitrogen oxides are found in the exhaust pipe, the urea tank automatically sprays out the diesel exhaust gas treatment fluid, and the diesel engine exhaust treatment fluid and nitrogen oxides undergo redox reaction in the SCR catalytic reaction tank to generate pollution-free nitrogen and water vapor discharge.

1. Vehicle urea is a product used for diesel vehicle exhaust treatment, which must be added to the national five and six diesel vehicles.

2. Vehicle urea is added to the urea pump of diesel vehicles, as shown in the figure below, the general urea tank is marked with a nameplate on the car, which can be seen.

3. When filling with urea, you can add it directly to the urea tank, pay attention to the hygiene around the urea tank buckle when filling, and don't let the dirt be added to the tank with the urea liquid, if the tank mouth is not convenient to fill, you can use the diversion pipe for filling, as shown in the figure below.

4. Now there is also a kind of self-priming deflector, as long as it is shaken up and down, the urea will be pumped into the urea tank, as shown in the following figure

Self-priming urea deflector.

Use a filling tube to fill the vehicle urea solution into the vehicle urea tank. The function of automotive urea is to convert the nitrogen oxides in the automobile exhaust into harmless nitrogen and water, which is energy-saving and environmentally friendly, so that the vehicle can meet the national exhaust emission standards. It is generally used in diesel vehicles.

The harmful substances in diesel exhaust are mainly nitrogen oxides and particulate matter. In the engine, the emission of particulate matter can be reduced by technical means, so that the exhaust gas is dominated by nitrogen oxides. By injecting urea into the exhaust aftertreatment unit, the urea is broken down into ammonia at high temperatures, which reacts with nitrogen oxides under the action of a catalyst to produce harmless nitrogen and water.

This unit is called an SCR aftertreatment system.

The SCR system consists of a urea tank (containing a diesel exhaust gas treatment fluid) and an SCR catalytic reaction tank. The operation process of the SCR system is as follows: when nitrogen oxides are found in the exhaust pipe, the urea tank automatically sprays the diesel exhaust gas treatment liquid, and the diesel exhaust gas treatment liquid and nitrogen oxides are dismantled in the SCR catalytic reaction box for redox reaction, and pollution-free nitrogen and water vapor are discharged next to Chanyu.

If the diesel exhaust fluid is not loaded, or is not of sufficient purity, or is of poor quality, the vehicle engine will automatically slow down. At the same time, the inferior diesel exhaust gas treatment fluid will contaminate the catalyst in the SCR catalytic reaction tank, causing serious consequences.

According to national standards, there are strict requirements for the density, refractive index, alkalinity, metal ions, sundries and other contents of automotive urea, and the use of automotive urea is mainly to reduce harmful nitrogen oxides in exhaust gas into nitrogen and water, which is generally used in diesel vehicles.

Automotive Urea, a liquid used in SCR technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. It is composed of high-purity urea and deionized water. The manufacturing process of car urea is relatively complex, mainly tap water, pretreatment, first-stage reverse osmosis, second-stage reverse osmosis, EDI system, ultrapure water storage tank, material storage tank, homogenization system, primary filtration system, decolorization system, extraction, purification, and finished products.

The harmful substances in the exhaust of diesel vehicles are mainly nitrogen oxides and particles, and the emission of particles can be reduced by technical means inside the engine, and the remaining exhaust gas is mainly nitrogen oxides, and then through the injection of automobile urea into the exhaust after-treatment device, so that the urea is decomposed into ammonia at high temperature, and under the action of the catalyst, it will react with nitrogen oxides to generate harmless nitrogen and water, this process is called SCR post-treatment system.

Hope this helps, hopefully!!

AdBlue is composed of high-purity urea and ultrapure water. After mixing at room temperature, it can become a vehicle urea solution. But the conductivity of water is best in the following, the fewer ions in all aspects, the better, and the purity of urea is the most important.

Urea is mainly used in vehicles to reduce harmful nitrogen oxides in exhaust gases to nitrogen and water. It is generally used in diesel vehicles.

The harmful substances of diesel vehicle exhaust are mainly nitrogen oxides and particles, and particle emissions can be reduced by technical means inside the engine, so that nitrogen oxides are mainly used in the exhaust gas, and urea is injected into the exhaust gas after-treatment device, which is decomposed into ammonia at high temperature, and will react with nitrogen oxides under the action of the catalyst to generate harmless nitrogen and water, this device is called SCR post-treatment system.

AdBlue is a diesel exhaust treatment fluid used in diesel engines to reduce nitrogen oxide pollution in diesel vehicle exhaust gases using SCR technology. It is composed of high-purity urea and deionized water.

Exhaust gas treatment fluid, commonly known as vehicle urea, is a consumable that must be used in SCR technology, mainly used for exhaust gas treatment of diesel engines.

There is a separate container on the truck to store AdBlue solution, and water and diesel fuel cannot be added to the urea solution during use. When the engine starts working, the ECU accurately measures the injection amount of urea solution according to the operating conditions of the diesel engine, the temperature of the catalytic converter and the environmental state. The urea solution is injected into the exhaust pipe, where it is homogeneously mixed with the diesel engine exhaust and chemically reacts.

The function of automotive urea is to reduce nitrogen oxides in the exhaust gas of diesel engines, so as to achieve the effect of energy saving and environmental protection.

1. It mainly plays the role of purifying exhaust gas in the vehicle, and can react with nitrogen oxides in the exhaust gas to reduce hydroxide emissions.

2. AdBlue can optimize engine performance and fuel consumption at the same time, and less diesel consumption can be as high as 5 to 7%.

3. Urea is added to treat the hydroxide in it. Without urea, the exhaust gas emission cannot meet the standard.

4. Vehicle urea can be catalytically reduced to harmless hydrogen (N2) and water (H20) in the diesel exhaust selective catalytic reduction (SCR) system, which is to reduce the hydroxides in the diesel engine exhaust gas, so as to achieve the effect of energy saving and environmental protection.

The function of automotive urea is to reduce nitrogen oxides in the exhaust gas of diesel engines, so as to achieve the effect of energy saving and environmental protection. Specifically, automotive urea can be used in the selective catalytic reduction (SCR) system of diesel vehicle exhaust to catalytically reduce nitrogen oxides (NOx) in the exhaust gas into harmless nitrogen (N2) and water (H2O) discharge.

If the diesel exhaust fluid is not loaded, or the purity is not enough, or the quality is poor, the vehicle engine will automatically slow down. At the same time, inferior diesel exhaust gas treatment fluid can contaminate the catalyst in the SCR catalytic reaction tank, causing serious consequences.

Urea is a mixture of urea and deionized water. Deionized water is pure water that contains no metal ions. 1.

Vehicle urea is widely used in trucks, and vehicle urea is used in random blocks, especially diesel vehicles in China VI. The role of AdBlue is to react with engine exhaust to produce harmless nitrogen and water. Without urea, the nitrogen oxides emitted by the diesel engine will be discharged directly into the environment, and the human body will inhale nitrogen oxides for a long time and cause respiratory diseases.

Therefore, in order to better improve the environment, it is necessary to use vehicle urea. 2.The biggest difference between gasoline vehicles and diesel vehicles is that diesel vehicles have low temperatures and excrement is much larger than gasoline vehicles.

Gasoline vehicles can directly reduce engine excrement through three-way catalysis, but diesel vehicles can not reach the temperature and a large amount of dust can be discharged, so the use of three-way catalysis alone can not achieve the purpose of catalytic exhaust gas, so choose to use vehicle urea to react with exhaust gas and then discharge the harmless gas generated after the reaction to better protect the environment.
