How to use urea for diesel vehicles What percent of the vehicle needs to be added to urea

If the suction rod in the urea tank cannot be extended to the end, the regulations require that less than 20% will prompt, less than 10% will call the police, and the alarm light can be turned on for 50 hours after the alarm light is on. Even if the urea is light, it can be opened for a long time.

Diesel vehiclesUreaGenerally, it is added once every six months. The time for adding urea to diesel vehicles must be determined according to the application of the vehicle. In addition, the application of urea is shown on the dashboard of the vehicle.

When the remaining amount of urea in the car is less than about 20%, an alarm will prompt the driver to add urea in time, and urea is added for diesel engines.

In view of the fact that diesel engines emit nitrogen oxides during operation, they pollute exhaust gases, which are harmful to the atmosphere and the human body.

The role of urea in diesel carsDiesel vehicles plus urea is used to purify and treat exhaust gas, all cars that use diesel engines must apply urea to purify and treat exhaust gas, otherwise the exhaust exhaust of diesel vehicles will exceed the standard, and fuel vehicles do not need to use urea to purify and treat exhaust gas; And the car is equipped with urea, and at the same time, it can improve the engine of Zheng Lijin's car.

Functional and energy consumption, the relative reduction of diesel engine use can reach 5-7%.

Hello, the purpose of adding urea to diesel vehicles is to reduce automobile exhaust emissions and protect the atmospheric environment.

The use of urea in the vehicle is to reduce the harmful nitrogen oxides in the exhaust gas into nitrogen and water, and the exhaust gas discharged by the engine is very serious to the atmospheric environment. The harmful substances of diesel vehicle exhaust are mainly nitrogen oxides and particles, and the emission of particulate matter can be reduced through the exhaust gas treatment device, after the use of urea in the car, as long as the car engine is running, the urea used by the car will be injected into the exhaust gas treatment device, and the urea can be ammonia gas at high temperature. Ammonia will react with nitrogen oxides under the action of catalyst to form harmless nitrogen and water, in order to make the emission of diesel vehicles meet the standard, EFI diesel engines must add urea, diesel vehicles can reduce pollutant emissions after using urea, making the car more environmentally friendly.

There is a special urea tank on the diesel car, urea is added in it, as long as the engine is running, urea will be consumed, generally 100 liters of diesel consumes about 4 liters of urea, which should be decided according to the engine displacement, and added in time.

Hope it helps!

It is specially used to treat nitrogen oxides in diesel exhaust gas, reduce them into nitrogen and water, and avoid diesel engine exhaust exceeding the standard.

The reason why diesel cars should be addedUreaIn fact, the main purpose is toProtecting the environmentto protect the atmosphere, because cars that burn diesel cars will emit thisNitrogen oxidesIn order to turn this nitrogen oxide into nitrogen and water, urea needs to be added。After adding urea, the exhaust gas discharged from the engine will naturally reduce pollution and meet the relevant regulations of environmental protection. There are some diesel cars in the countryside, especially some mountain climbers, these mountain climbers generally do not add urea, but if he climbs the hill at full speed, we can see that the gas emitted by this engine is thick smoke billowing black, and there is a very bad smell.

If the diesel car does not add urea, this situation will naturally occur, which will inevitably affect the cityscape in the attempt, and will also pollute the air in the city。In order to solve the problem of air pollution, it is also to solve some harmful substances and some particles emitted by this exhaust gas, so as to avoid respiratory tract infections caused by people's breathing.

For the sake of people's health, it is necessary to add this urea.

For diesel cars, in fact, to a certain extent, it is also necessary to increase this urea, generally speaking, many of the current cars are this gasoline version, rarely use the diesel version, and the diesel version generally needs to add a small amount of urea。After all, cars that burn diesel will emit this oxygen and nitrogen compound, causing environmental pollution and causing great harm to the human body. For the sake of people's health, measures must be taken to reduce the occurrence of such damage.

When adding urea to the vehicle, there are actually many things that need to be paid attention to, such as not adding it to the diesel, not adding this impurity when adding it, if some impurities are added when adding urea, then there is still some damage to the system of the vehicle。Generally speaking, when adding this urea, there will be this professional diversion and addition tube, and there is also this filtration device, the purpose is to avoid impurities from entering the irrigation body of this vehicle.

It is mainly to protect the atmospheric environment, in order to ensure the emission of automobile exhaust, in line with the requirements of vehicle environmental protection. It is necessary to add urea, you should pay attention to the amount of urea, but also pay attention to the requirements of driving, pay attention to chemical reactions, understand the standards of exhaust emissions, pay attention to the power of the car, and the role of urea liquid.

After adding urea to diesel vehicles, it can exert the greatest power** and effectively reduce insufficient fuel combustion. There is no need to add urea to diesel cars, and it should be noted that the correct way and method need to be used when adding urea, and it cannot be added blindly.

This will be more environmentally friendly, and it will also meet the emission standards and can remove nitrogen oxides. Of course, it is needed, we must pay attention to grasp the proportion, pay attention to the method of addition, and don't add too much.

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

Vehicle urea plays a key role in the power and fuel consumption of diesel vehicles, if you do not load diesel exhaust treatment fluid, or use urea solution of poor purity and poor quality, it will form an active deceleration of the vehicle starter. Together, the inferior diesel exhaust gas treatment fluid will contaminate the catalyst in the SCR catalytic reaction tank, resulting in damage to the components of the aftertreatment system.

The qualified urea solution is composed of ultra-pure urea and pure water based on NOx. AdBlue is selectively catalyzed with NOx products to convert it into nitrogen, oxygen, and water, and then reduce nitrogen oxide emissions. SCR system for diesel engines with all Euro IV and Euro V emissions.

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.

Among the pollutants emitted by the vehicle, no matter how the engine data is adjusted for NO and PM, there must be a value that exceeds the standard.

If the PM particles exceed the standard, it is through the deterioration of the combustion of EGR, and the post-treatment plus POC treatment of the particles, the disadvantage of this technology is high fuel consumption and poor combustion efficiency, but do not add urea, and the emission level is up to China IV;

If the NO is high, it means that the engine burns at high temperature, the power is strong, the particles are fully combusted, and the fuel consumption is low, but urea should be added in the later stage to reflect the NO in the exhaust gas, so that the emission meets the standard.

This is a matter of consulting physics experts and automotive experts, with different perspectives and different perspectives. But all in order to improve the effect, in general, diesel vehicles plus urea is to reduce vehicle exhaust emissions and protect the atmospheric environment. The purpose of using urea in vehicles is to reduce harmful nitrogen oxides in exhaust gas into nitrogen and water, and the exhaust gas discharged from the engine is very serious to the atmospheric environment.

With the continuous improvement of environmental regulations, the exhaust gas discharged from the engine is in order to comply with the regulations, so there is an exhaust gas treatment device. The harmful substances in the exhaust of diesel vehicles are mainly nitrogen oxides and particles, and the particulate matter can be reduced through the exhaust gas treatment device. Do you understand?

The purpose of adding urea to diesel vehicles is to reduce harmful nitrogen oxides in exhaust gas into nitrogen and water, reduce emission pollution, and promote environmental protection.

Why do diesel engines need to add some urea, and what are the benefits? Today is a long time to see.

In order to reduce harmful gases in exhaust emissions. Add urea, add good urea. Chinese car Hongkang Chun, you deserve it.

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. The purpose of using urea in vehicles is to reduce harmful nitrogen oxides in exhaust gas into nitrogen and water. With the improvement of the requirements of national environmental protection regulations, the exhaust gas directly discharged from the engine can no longer meet the requirements of the regulations, so there is a chain management device at the rear of the exhaust gas. 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.

2. In order to meet the emission standards, EFI diesel engine vehicles must add urea. Urea can reduce the nitrogen oxides in the exhaust gas, reduce emission pollution, and make the vehicle more environmentally friendly. At present, most diesel engines adopt selective catalytic reduction technology, the general principle is that after the engine exhaust gas is discharged from the turbine, it directly enters the cavity to the exhaust pipe and goes through the catalytic converter conversion first, and then the urea nozzle on the exhaust pipe will spray out the urea aqueous solution under the control of the computer, and the nitrogen oxides in the urea aqueous solution and the tail gas produce a redox reaction in the SCR catalytic converter, and finally the exhaust gas is reduced to nitrogen and water and then discharged.

Diesel vehicles need to burn diesel fuel during operation, which will produce a nitrogen oxide that pollutes the environment. The addition of urea can reduce nitrogen oxides to nitrogen for pollution-free emissions. Therefore, urea is added neither to save fuel nor to improve the power of diesel vehicles, but only to make the exhaust gas meet environmental protection requirements.

After all, the country still attaches great importance to environmental protection, and the emission of automobile exhaust should also comply with relevant regulations. Diesel cars also need to add urea, otherwise the exhaust gas emitted by the car will smell particularly bad, and may be caught by the traffic police and then deducted money.

Why should urea be added to diesel cars for the sake of ruining Zheng?

When hearing the word urea, many people think of crops, after all, it is a chemical fertilizer. Most people drive gasoline cars that will directly add gasoline, and gasoline will also produce some gases that pollute the environment after combustion, but engineers add a three-way catalyst to the car, which can reduce this pollutant and make the exhaust no longer pollute the environment. Diesel vehicles emit more pollutants in their exhaust fumes, and it is useless to add this degradant, and the researchers selected urea through real experiments.

The addition of urea can make the pollutants in the exhaust gas harmless, so as to meet the requirements of environmental protection.

Do diesel cars also need urea?

Of course, it needs to be added, because diesel cars also burn diesel, so it is useless to add other things, or it will pollute the environment, it is better to add urea directly. However, some netizens raised questions, this netizen is located in the Northeast, the temperature is relatively low, and urea is directly frozen in the case of low temperature, and it cannot be added to the car at all. Therefore, netizens hope that researchers can study diesel and improve the workmanship ratio of fuel, so as to reduce the nitrogen oxide content in the exhaust gas, which will naturally not pollute the air.

It can be seen that drivers need to know a lot of knowledge, so that they can avoid a lot of problems and pay less fines.

Diesel vehicle exhaust emissions are relatively large, Tian Songsui plus urea can reduce the carbon oxides in the lungs, reduce the emission of pollutants, can be more environmentally friendly, Chang Hui added these substances are resistant to the cherry group to make it restore harmless substances, so as long as it is a diesel car is need to be added.

The purpose of adding urea is to protect the environment, reduce the exhaust emissions of the vehicle, and reduce the pollution of the environment.
