What about using domestic diesel exhaust fluid? In fact, there is a little gap between the data of imported diesel exhaust fluid and that of domestic diesel exhaust fluid. At present, the certification of diesel exhaust fluid mainly starts from the usage amount of urea, not only from the policy, but also from the domestic standards. Practical analyses are also necessary.

According to the survey, there is a little difference between the data of imported diesel exhaust fluid and that of domestic diesel exhaust fluid. The production and operation process of the most of urea should be analyzed practically. Thus, the domestic products with elements of innovation and the development effect of output are not quite appropriate. In terms of the import, the import output of diesel exhaust fluid is not particularly large due to a certain improvement of the domestic production of diesel exhaust fluid. In terms of the technological level, the standard of domestic products is not much different from international standards.

According to these aspects, it can be seen that the consumption level of selecting high-quality diesel exhaust fluid is roughly the same in the future. Therefore, compared with the effect of imported diesel exhaust fluid, the use and output of diesel exhaust fluid are good and conform to its requirements. So, judging from the comparison with data, the import proportion of the most of diesel exhaust fluid is the same. Only after an in-depth analysis can a kind of diesel exhaust fluid be truly applied in the automotive field.

The selection of diesel exhaust fluid needs to conform to its standards. It can be seen that there is little difference from the aspect of domestic product certification.
