First of all, the urea nozzle test needs to be conducted on the premise of ensuring that the urea pressure test is correct.If the pressure test is abnormal, the urea nozzle test must be completed before starting.After checking the normal pressure test, enter the opening degree of urea pump 40, and the opening degree of urea nozzle 50. Click "urea nozzle test" to conduct atomization test of the nozzle.Under normal circumstances, the urea pressure will rise slowly after the test is started, and finally stabilize around 9000hPa (the whole vehicle layout of different vehicles may fluctuate, with the fluctuation range between 8000 and 12000hPa).Test description: the urea nozzle test must listen to the sound, observe the situation of urea atomization to determine whether the urea nozzle is damaged
Urea nozzle test: the sound of magnetic valve opening can be heard clearly near the nozzle (the valve is opened at a frequency of 1HZ).If no sound is heard, please confirm whether the ECU program is the latest program, whether the urea pressure has reached 13000hPa, and whether the wire bundle is connected normally.If you can hear the valve open all the time, but no urea is released, the urea pressure has reached 9000hPa, indicating that the urea nozzle is blocked.On the contrary, if urea is seen coming out of the nozzle during the pressure test, the nozzle valve is damaged.Normal urea nozzle at work: when urea pressure reached 9000 hpa, should be to see very good atomization taper fog particles, if there is a droplet of urea solution, also is a kind of damage of the nozzle.Sometimes, because there is urea crystallization in the pipeline, it may lead to poor test results in the previous several times. You can try more than a few times, and generally recover after 3-5 times.
Many nozzles can be blocked by a hot blister.In case of blockage caused by damage to the urea nozzle pipe joint, the pipe joint should be replaced for treatment.
