Applicable to Mercedes-Benz Volkswagen Ford urea pump nozzle assembly 0444021021 0444021046

        What is the purpose of the nozzle? The nozzle is a key component in many kinds of spraying, spraying, oil spraying, sandblasting, spraying and other equipment, and plays an important role. Nozzles are widely used, so the classification of nozzles is also many.

For post-treatment maintenance, in fact, our most common faults are concentrated in the urea nozzle and urea pump above, here we put the post-treatment urea pump and urea nozzle fault characteristics sort out: 

1. Do not burn urea

Description: During the normal use of the vehicle, the amount of urea was found to be unchanged.
2. Vehicle power is insufficient

Description: When the vehicle is driving, the engine is insufficient, which gives the driver the feeling of being weak.

3. Urea pump does not work

Description: When the vehicle is running, the urea pump does not work properly.

4. The urea lamp is steady on

Description: When the vehicle is running, the urea fault indicator on the instrument is steady on.

5. Large urea consumption

Note: The urea consumption value is greater than the value of 100L diesel oil consumption of 10L urea.

6. Leakage crystallization
Description: There is leakage and crystallization on the urea pump.

7. An internal fault occurs

Part of the internal components of the urea pump system failed, resulting in a fault in the system.

8. Failure to build pressure

Note: When the urea pump works abnormally, the detection software displays the fault information as failure to build pressure.

9. Poor suction

Note: After stopping the urea pump pumping pipeline residual liquid process is not smooth.

10. Nozzle does not work

Description: When the post-treatment system is working, the nozzle does not spray urea
