What is the urea added to diesel cars made of?Why do trucks need to add urea

Diesel vehicles generally need to add urea, which is mainly to neutralize the exhaust gas, so that the originally polluting compounds become substances that are not harmful to the human body. Under normal circumstances, the direct exhaust of diesel vehicles will have a lot of polluting gases, which is very bad for the air, and will damage people's health for a long time.

The working principle of adding urea to diesel vehicles

Car exhaust emits nitrogen oxides, which are harmful. After adding urea, the car will go through a certain treatment, so that the urea tank can automatically spray the urea solution when the car exhaust is discharged. At high temperatures, urea will automatically decompose into ammonia, which can react with nitrogen oxides in car exhaust to generate nitrogen and water vapor. Nitrogen and water vapor are non-polluting and do not cause air pollution.

What will be the impact of diesel vehicles without urea

1. First of all, it will cause environmental pollution, because there is no way to neutralize the pollutants in the vehicle exhaust, and direct emissions will pollute the air.

2. Vehicle exhaust emissions will exceed the standard. If it encounters annual inspections, etc., it is likely to fail, and we will be required to make rectifications. In serious cases, we need to accept certain penalties. At present, the exhaust emission standards formulated by my country can only be met after adding urea to trucks.

3. Cars that do not add urea may reduce the power effect. It feels that the car cannot use the force, and the power performance will also decrease when driving.
