In addition to the consumption of urea water solution and oil, there are generally the following reasons:

1. When the nitrogen and oxygen sensor detects that the exhaust gas of the vehicle is not up to standard, urea will be sprayed more;

2. Urea nozzle failure, resulting in multiple injection of urea;

3, the problem of urea pump, urea pump internal failure will lead to pressure failure, or gas-assisted urea pump is more likely to cause more burning urea;

4, the problem of exhaust temperature sensor, if the exhaust temperature sensor failure, the temperature did not reach 180 degrees began to spray urea, this will also cause burning urea;

5, vehicle fuel and gas quality problems, poor quality, the engine will produce harmful gas in the tail gas will be more, so it will need more urea to participate in the reaction, resulting in urea consumption;

6, road conditions, if the long-term road or undulating sections, it will cause insufficient combustion in the vehicle engine, the quality of the exhaust can be imagined, but also cause urea consumption;

7, the engine itself fails, that is, when the common rail system fails, it will also make insufficient combustion, exhaust quality is not up to standard, and ultimately cause urea consumption;

8, the computer board program problems, usually the computer board program will limit the amount of urea consumption, if the computer board program problems, will also cause urea consumption.
