What is the principle of car plus urea, and what role does car plus urea play

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.

There is a special urea box on the car, and urea is added to this box. As long as the car is running, urea is consumed. So add it in time as well.

Generally, 100 liters of diesel fuel consumes about 4 liters of urea. It is related to engine displacement, model, manufacturer, etc. Different road conditions and different loads will cause different urea consumption.

Vehicle urea mainly plays a role in purifying exhaust gas in the vehicle, and can react with nitrogen oxides in the exhaust gas to reduce nitrogen oxide emissions. AdBlue optimizes both engine performance and fuel consumption, up to 5-7% less diesel. I have used a Baoyi brand of car urea before, and the fuel saving effect is not bad.

Reasons and practices for adding urea

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 nitrogen oxide emissions.

2. Vehicle urea can optimize engine performance and fuel consumption at the same time, and less diesel consumption can be as high as 5-7%. I have used a Baoyi brand of car urea before, and the fuel saving effect is not bad.

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

The use and function of vehicle urea

For cars, trucks, buses and heavy-duty off-highway diesel vehicles equipped with SCR (Selective Catalytic Reduction Exhaust Aftertreatment) systems, it purifies vehicle exhaust gases and reduces NOx emissions in exhaust gases, while optimizing engine performance and fuel consumption, reducing diesel consumption by up to 6% and significantly reducing costs.

Urea is for diesel engines, because the diesel engine will discharge polluting gas nitrogen oxides when working, these gases are harmful to the atmosphere and the human body, human beings will absorb such gases for a long time will cause respiratory diseases, the country in order to reduce the damage of this gas to the atmosphere and human beings, will use urea, which involves a catalytic reaction, when urea meets the nitrogen oxides discharged by the diesel engine. A chemical reaction occurs to convert nitrogen oxides into nitrogen and water is discharged, both of which are harmless to the atmosphere and the human body.

Automobile urea is mainly injected into the back end of the catalytic converter to produce a chemical reaction with the exhaust gas, so as to reduce the exhaust emissions. This technology is BMW.

First of all, the emission standard can reach Euro VI.

The scientific name of automotive urea is diesel exhaust treatment fluid. It is used in diesel engines. It is a liquid used in SCR technology to reduce nitrogen oxide pollution in diesel vehicle exhaust.

First of all, your question, because the direction of environmental protection is now important, the emission flow of automobiles is particularly serious, so the addition of urea to the car is a liquid that can reduce nitrogen oxide pollution in the exhaust of diesel vehicles.

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

Knowledge expansion: The scientific name of automotive urea is diesel exhaust treatment fluid. It is used in diesel engines. It is a high-purity urea and deionized water used in SCR technology.

Why does urea in cars reduce environmental pollution? Today is a long time to see.

The main use of vehicle urea is to reduce nitrogen oxides in the exhaust of diesel vehicles to ensure that the exhaust emissions can meet the national VI emission standard.

The main principle is.

The right is that the vehicle urea solution reacts with nitrogen oxides through a catalyst under high temperature conditions to reduce nitrogen oxides into nitrogen and water that are non-polluting to the atmosphere.

Nowadays, domestic automotive urea is relatively well-known in Jiangsu Colan and Henan Hongkang.

Diesel-burning vehicles, the exhaust emissions currently meet the standards of not China V and China VI, and urea needs to be added to the exhaust emissions to turn the harmful nitrogen oxides in the exhaust into nitrogen and water, so as to meet the current national emission standards. Generally, 100 litres of diesel fuel consumes a proportion of 4 litres of urea.

Product attributes: AdBlue for vehicles.

Uses: The use of urea solution of different quality is also different for the maintenance of the vehicle. While.

The purity of the urea solution selected is not enough, and when there are impurities such as particulate matter and heavy metal ions, it will cause serious damage to the nozzles, filters and other parts of the vehicle SCR system, and bring unnecessary economic losses. If the chemical composition of low-quality urea solution is not high, when there are heavy metals and other chemical components, it will have a chemical reaction with the catalyst to reduce the effect of tail gas conversion, or even lose its effect. Therefore, when choosing urea solution, we should try to choose high-quality products to control the maintenance cost of the vehicle.

If the density is too high, the vehicle will also have an alarm reaction, and the standard concentration of urea water for vehicles is between. Chuandong Chemical's vehicle urea is a reducing agent for eliminating harmful nitrogen oxides in the exhaust gas after diesel combustion, with appropriate purity, low heavy metal content and less impurities, which can make diesel vehicle exhaust emissions meet the national, European and European emission standards. It works together with the vehicle-mounted SCR catalytic reduction system to convert harmful nitrogen oxide gases emitted by diesel engines into harmless water vapor and nitrogen, thereby eliminating pollution to the atmosphere.

Purify exhaust gases, reduce pollution in sedan cars, etc.

It mainly plays a role in purifying exhaust gas in the vehicle, and vehicle urea can be selectively catalyzed by the closed leakage reduction of diesel vehicle exhaust, and in the SCR system, vehicle urea is usually 32 urea and 67 of locust seed water.

Through the intelligent control of the SCR system, the mixer truck will not start when the urea solution in the storage tank is insufficient, and 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 the purity requirements of raw materials for automotive urea are higher than those for general industrial use, 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）。

1. Diesel engine: The car should add urea to the car for the diesel engine, because the diesel engine will discharge harmful gases and nitrogen oxides, causing environmental pollution, and long-term inhalation of this exhaust gas by humans will cause great harm to the human body.

In order to reduce this harm, the car using the diesel engine should add urea, which has a catalytic function, and will produce a chemical reaction when encountering nitrogen oxides, turning nitrogen oxides into nitrogen and water and then discharging them.

2. Catalytic reduction reaction: the qualified urea solution is the synthesis of ultra-pure urea and pure water with NOx. AdBlue is converted into nitrogen, oxygen and water through selective catalytic reduction reaction with NOx products, thereby reducing nitrogen oxide emissions.

Suitable for all Euro IV and Euro V emission diesel engine SCR systems.

3. There will be a special urea tank in the diesel car, and the urea in the urea tank will continue to be consumed in the process of exercising, and we need to supplement the urea in the urea box in a timely manner.

The principle of automobile plus urea: the harmful substances discharged by the car are mainly nitrogen oxides and particles, and the particle emissions can be reduced by technical means of accompaniment in the engine, so that the exhaust gas is mainly nitrogen oxides, and the urea is injected into the exhaust gas post-treatment device, and the urea is decomposed into ammonia at high temperature, and the nitrogen oxides will react under the action of the catalyst to generate nitrogen and water without reed damage. Here's a little more about AdBlue for Automotive:

1. When the residual amount of automotive urea is less than about 20%, Zheng Cha should add automotive urea in time. 2. Vehicle urea is composed of high-purity urea and deionized water, under normal circumstances, vehicle urea is harmless to the human body.

The addition of automotive urea mainly plays a role in reducing automobile pollution. Urea has a catalytic effect, which can make nitrogen oxides undergo a chemical reaction and convert them into non-toxic and harmless nitrogen and water, thereby purifying the tail gas.

Cars with diesel engines should add urea, because diesel engines will emit harmful gases and nitrogen oxides, causing environmental pollution. Long-term inhalation of this exhaust gas by humans will cause great harm to the human body. To reduce this hazard, urea, which has a catalytic effect, should be added to the bleeding of cars with diesel engines.

When nitrogen oxides are encountered, a chemical reaction occurs, and the nitrogen oxides are turned into nitrogen and water, which are then discharged.

Qualified urinary solution is NOx synthesized with ultra-pure urea and pure water. AdBlue solutions can be converted to nitrogen, oxygen and water through selective catalytic reduction reaction with NOx products, thereby reducing NOx emissions. Suitable for all Euro 4 and Euro 5 emission diesel SCR systems.

There will be a special urea tank in the diesel car, and the urea in the urea tank will be continuously consumed during the driving of the vehicle. We need to replenish the urea tank in a timely manner. If urea is not supplemented for a long time, it will not only affect the pollution emissions of the vehicle, but also affect the driving speed and power of the vehicle.
