Why do trucks add urea solution? What is the truck used for urea solution?

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.

AdBlue is a must-have product for heavy-duty diesel vehicles to meet the China IV emission standard. Vehicle urea refers to a urea aqueous solution with urea concentration and solvent of ultrapure water, and the raw materials are special raw materials for vehicle urea and ultrapure water.

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.

Why do you need to add urea to the tanks of trucks?

The function of the truck plus urea solution is mainly to purify the exhaust gas. Urea liquid is for the diesel engine of the truck, because the diesel engine will discharge the polluting gas nitrogen oxides when working, these gases are harmful to the atmosphere and the human body, and when urea encounters the nitrogen oxides discharged by the diesel engine, it will produce a chemical reaction, which will convert the nitrogen oxides into nitrogen and water and discharge, and the generation of nitrogen and water is harmless to the environment.

Hazards of not adding urea solution:In China, qualified urea solutions are generally synthesized from ultra-pure urea and pure water based on NOx. The urea solution produces nitrogen, oxygen, and water by reducing it with NOx, which reduces the excretion of nitrogen oxides.

The power and fuel consumption of diesel vehicles will be affected by urea, if the diesel car is not equipped with this exhaust treatment device, or is suitable for inferior products, it will lead to automatic deceleration of the vehicle engine, and will also have an impact on the catalyst in the SCR catalytic reaction tank, a single post-treatment device is damaged, not only has an impact on the environment, the maintenance cost of the post-treatment device is also very high.

1. It can reduce the harm of exhaust emissions to the human body.

Trucks emit polluting gases and nitrogen oxides when working, which not only affects the environment, but also causes cancer and affects the respiratory tract. Therefore, the regulations have strict requirements for the content of nitrogen oxides in diesel exhaust. The addition of urea can play a role in purifying the exhaust gas, which can react with the nitrogen oxides in the exhaust gas and reduce the emission of nitrogen oxides.

2. Reduce costs.

If urea solution is not used, it will cause the vehicle engine to automatically slow down, and will pollute the catalyst in the SCR catalytic reaction tank, resulting in damage to the components of the aftertreatment system and increasing the overall cost.

The function of large trucks and urea solution is mainly to purify exhaust gases

AdBlue solutions are mainly used to convert harmful nitrogen oxides from exhaust gases into hydrogen and water. It is generally used in diesel vehicles. The harmful substances in diesel exhaust are mainly nitrogen oxides and particulate matter.

In automobile engines, this technology can reduce the emission of particles, so that the exhaust gases are mainly nitrogen oxides. The urea solution is injected into the exhaust gas after-treatment unit. The urea solution decomposes at high temperatures into ammonia, which reacts with nitrogen oxides and is converted into harmless hydrogen and water by the action of a catalyst.

This device is called a thyristor post-virtual nano treatment system.

The origin of AdBlue for Vehicles

As the environmental protection departments of various countries propose to further reduce the nitrogen oxide pollutants emitted by diesel engines. It is commonly known as the Euro IV standard in China.

Engine manufacturers are starting to use SCR (Selective Catalytic Reduction Technology) to meet the requirements of environmental authorities.

Diesel engine exhaust treatment fluid (commonly known as automotive urea, automotive urea, automotive environmental protection urea, diesel vehicle exhaust purification liquid) is a necessary consumable in SCR technology.

The main purpose is to integrate the nitrogen oxides of polluting gases when the diesel engine is running. Because this compound can pollute the air, and long-term breathing of this kind of gas is very harmful to the human body.

However, the use of urea and its synthesis can achieve a catalytic reaction, then the nitrogen oxide compound is converted into nitrogen and water after the chemical reaction with urea, and it is discharged at this time, which is not much harmful to the human body and the environment.

The most basic function of the vehicle urea solution is to convert the nitrogen oxides in the tail ridge of the car into harmless nitrogen and water, which is energy-saving and environmentally friendly, and Xinxian enables the car to meet the national exhaust emission standards.

Through the intelligent control of the SCR system, when the urea solution in the storage tank is insufficient, the car will not start, in order to ensure the normal driving of the vehicle, sufficient urea solution should be prepared.

Extended information: Urea for vehicles is an aqueous urea solution with a concentration and volume of ultrapure water, and the raw materials for the production are special raw materials for urea and ultrapure water, and the key point is the purity of raw materials. From the perspective of production process, although automotive urea has high requirements for the purity of raw materials, it is envied by general industrial needs, but the current domestic process can already meet the needs of practical applications.

AdBlue must use the first grade ultrapure water of the electronics industry. Due to the fact that the SCR catalyst carrier of automotive urea is very prone to metal ion poisoning and loses its catalytic effect, the automotive urea solution must use first-class ultrapure water (resistivity 18m?) in the electronics industrycm）。Hope.

The car should add urea in order to meet the emission standards, and the impact of the car not using urea: 1. The emission exceeds the standard and causes pollution to the environment; 2. The chemicals in the Tongchang system of the automobile system will oxidize, and the urea nozzle will be blocked, so that the whole system will be scrapped; 3. The dynamics of the vehicle decrease. The effects of urinary transport are:

Treating exhaust gases reduces pollutants in exhaust gases, optimizes engine performance and fuel consumption. The reasons for the low alarm of urea lamp are: 1. The urea pressure is too low and the urea consumption is high; 2. Insufficient power, urea consumption is too high or too low; 3. The dashboard is faulty.

The method of eliminating the alarm of urea lamp is: 1. Replace the urea solution; 2. Replace the water heating valve; 3. Replace the plug of the urea pump and the power supply module.
