National six diesel vehicles on the car urea requirements standard, national six car with what urea good

Now the national six diesel vehicles are equipped with urea injection system, urea system can effectively purify the harmful substances in the exhaust of diesel vehicles. So what are the requirements for automotive urea for national six diesel vehicles? In fact, as long as the product standards in line with GB295182013, the concentration of 32.5%, the urea solvent must be ultra-pure water, these three conditions of urea can meet the National VI diesel car use.

What are the requirements for urea in a diesel car?

1, must meet the national standard. The urea solution used in the national six models must comply with the product standards of GB295182013;

2, the concentration of automotive urea solution is 32.5%. If you use more than the concentration of standard urea, then the vehicle's urea system is easy to clog, if less than can not effectively reduce the generation of nitrogen oxides in the exhaust;

3, urea solvent must be ultra-pure water. The so-called ultra-pure water refers to water without any impurities or minerals, the more common pure water is distilled water.

What brand of urea is better

At present, the more famous brands are Rundi environmental protection, Mei Fengjia, Kelanin, Kunlun Star and Yuetai Hailong. Among them, Keranin and Kunlun Star are the more recommended brands for truck drivers.

In fact, usually we do not have to be too obsessed with the brand of urea solution, as long as we choose the urea solution is in line with the GB295182013 product standards can be assured that the use of words. It is not recommended that truck drivers mix their own urea solution, because the urea solution needs to use high-purity urea and ultra-pure water to configure, but also for the concentration of higher requirements.

How to avoid the failure of the urea system

1, the use of standardized urea solution. If we use the urea solution concentration is not up to standard or more impurities, then it is easy to lead to urea pump or urea pipeline blockage;

2, avoid private disassembly of the urea system. The structure of the urea system is relatively complex, if non-professionals to dismantle it is easy to cause the fault light on;

3, regular replacement of the urea cartridge. The urea filter can effectively prevent impurities from entering the urea injection system, so it is necessary to replace it regularly.
