How to quickly solve it without burning urea?How to repair the national five car without burning urea

When vehicles do not burn urea, the problem is often not the sameerror code, But a row of fault codes, which need to be checked one by one. You can check the relevant codes through the service station diagnostic instrument. If the vehicle does not use urea or uses products with insufficient purity and inferior quality, it will limit the torque output of the engine. At the same time, poor quality urea will contaminate the catalyst in the SCR catalytic reaction tank, causing serious consequences.Therefore, if you use high-quality urea products, onceFindThere is a lot of urea in the vehicle, which should be overhauled in time.

No burning urea solution

1. Check whether the post-processing wiring harness and sensor are in normal contact, and if there is any problem, adjust and repair it in time;

2. Check whether the urea pipeline is normal and whether there is leakage. If there is, it needs to be replaced in time;

3. Check whether the urea pump is working normally, once it is found to work abnormally, it is necessary to check the cause of the failure in time;

4. Check whether the urea nozzle is working normally. If it is found that the nozzle is blocked or cannot be opened normally, it should be cleaned or replaced in time.

Reasons for not burning urea

Problems in post-processing will result in no burning of urea; blockage of the pipeline or filter element will indirectly lead to no burning of urea; failure of the heating relay will also lead to low urea temperature and no burning of urea and blockage of urea without burning.

Automobile urea is also called exhaust gas treatment liquid, which is a liquid used in SCR technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. The vehicle does not burn urea, which means that the SCR system is not working properly. Although it can save money for urea, the chemical substances in it will be quickly oxidized and the urea nozzle will also be blocked, causing the entire system to be scrapped. The cost of replacing the SCR system is far more than the consumption. The cost of urea is much more expensive.
