Why do Mercedes Benz diesel cars add urea?

The U.S. version of the model needs to be added.

It is added to purify diesel exhaust gas, and it will not ignite if it is not added.

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 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. It is a special vehicle urea, which is used for denitrification of diesel vehicle exhaust. That is, NOx in the exhaust gas reacts with NH3 decomposed from urea to form N2.

to reduce air pollution.

In the European and American markets, they want to meet their stringent emission requirements.

Diesel vehicles do have an exhaust after-treatment system installed. That is, what is commonly known as urea tank in our country.

Mercedes GL350 is about a kilometer plus a barrel.

It costs about 1 cent a kilometer of urea solution

Urea carries a bucket of 10L in the car.

Hello, I am glad to answer for you, diesel car plus urea liquid is to reduce vehicle exhaust emissions, protect the atmospheric environment, the use of urea in the vehicle is to reduce the harmful nitrogen oxides in the exhaust into nitrogen and water, the exhaust gas discharged by the engine is very serious to the atmospheric environmental pollution, with the continuous improvement of the requirements of environmental protection regulations, the exhaust gas discharged by the engine is in accordance with the regulations, there is an exhaust treatment device. 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. Hope it helps, thank you.

Urea must be added to diesel vehicles.

If urea is not used, the vehicle's engine will automatically slow down. And if the urea is not pure enough or the quality is shoddy, it will also cause the automatic deceleration of the vehicle engine.

Urea is a common name, the formal name is diesel exhaust treatment fluid, and other names include automotive urea, automotive urea, automobile environmental protection urea, etc. Urea is an essential consumable in SCR technology.

SCR technology is a technology invented by engine manufacturers in order to meet the requirements of environmental protection departments. SCR stands for SelectiveCatalyticReduction Technology. Urea is a liquid used in SCR technology to reduce nitrogen oxide contamination in diesel vehicle exhaust.

Urea consists of deionized water.

and 10% high-purity urea.

AdBlue can be used to remove nitrogen oxides from diesel exhaust in a selective catalytic reduction (SCR) system.

NOx) catalytically reduced to harmless nitrogen (N2) and water discharged. Under normal circumstances, urea is harmless to the human body. However, when urea is at high temperatures, it will decompose ammonia gas.

If you are exposed to ammonia for a long time, you may experience symptoms such as hyperpigmentation or ulcers.

The steps for adding Mercedes-Benz GL350 urea are as follows:

The imported urea water is loaded with a connecting pipe on the barrel body, the design is very scientific, and the quality of the barrel is really good.

2. The filling port of urea is under the trunk plate, and after lifting it up, you will see this Dongshi stupid Tanxi, this is pressed, and it will get up when you press it.

3. You can see this after you get up, ad-blue, you can lift it up after about half a turn.

4. This is the plug of the filling port inside, you can unscrew it, there is a connection plastic, and this mouth is the mouth of urea water filling.

5. The hose of urea water is connected to the bucket, and the other end is blocked with a finger to avoid spilling, and half a bucket can be added. Some vehicle warning lights are on, but after adding urea, the warning lights are still not automatically eliminated. If this is the case, it may be that the sensor sometimes cannot sense that it has been added in time, just go to 4S to set it.

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.

Summary. Mercedes-Benz diesel urea concentration refers to the addition of urea solution to the exhaust gas through the urea injection system during the driving process of the diesel vehicle to further clean the exhaust gas and reduce the emission of nitrogen oxides (NOx). Urea concentration is not a fixed value, and different vehicle types and engines will use different urea injection strategies under different conditions to achieve the best emission control effect.

Generally speaking, the urea concentration of the vehicle will gradually decrease with the increase of use time, and if the concentration is too low, the urea SCR injection system will fail, which will affect the performance and emissions of the vehicle. Therefore, it is very important for diesel car owners to regularly check the urea concentration and add new urea solution in time.

Mercedes-Benz diesel urea concentration refers to the addition of urea solution to the exhaust gas through the urea injection system during the driving process of the diesel vehicle to further clean the exhaust gas and reduce the emission of nitrogen oxides (NOx). Urea concentrations are not a fixed value, and non-combustible vehicles and engines use different urea injection strategies under different conditions to achieve the best emission control results. Generally speaking, the urea concentration of the vehicle will gradually decrease with the increase of use time, and if the thick skin hole is too low, the urea SCR injection system will fail, which will affect the performance and emissions of the vehicle.

Therefore, it is very important for diesel car owners to regularly check the urea concentration and add new urea solution in time.

Can you add, I don't quite understand it.

Summary. Hello, Mercedes Benz Diesel Urea Concentration is, which is the standard urea concentration of Mercedes Benz Diesel.

Hello, Mercedes Benz Diesel Urea Concentration is, which is the standard urea concentration of Mercedes Benz Diesel.

Can you elaborate on that a little bit more?

Urea is an organic compound, which is a compound of nitrogen and oxygen, which can be used for clean combustion in diesel engines. It can effectively reduce harmful substances such as nitrogen oxides, hydrocarbons and carbon oxides in automobile exhaust, thereby reducing the pollution of automobile emissions to the environment. The concentration of urea can be cavity excavated to vary according to the different automobile engines, and in general, the urea concentration of diesel engines is about the same.
