The urea we are talking about today is actually used to reduce the exhaust emissions of diesel vehicles, so as to achieve the effect of energy saving and environmental protection. Then some friends asked what would happen if the truck did not burn urea, and what is the reason for not burning urea, let's answer it in detail below.
When trucks do not burn urea for vehicles, the nitrogen oxides (NOx) in the exhaust gas cannot be catalytically reduced, so the exhaust gas released must be bad for the ecological environment. In addition, the power will also decrease. When the electronic control system fails to monitor the urea injection, it will forcibly restrict the operation of the engine to minimize exhaust gas emissions. If there is no urea for a long time, it is likely to cause damage to the part or the entire system. The cost of repair is not low, so it is better to repair it as soon as possible.
As for why the car urea is not burned, it is probably because the selective catalytic reduction (SCR) system has failed (the emission fault light is on).If you want to find out the cause of the failure, it is difficult to check manually by yourselfFindYes, it’s best to go to the relevant auto service shop for repairs (computer testing). After all, the scope of contact is too wide. It is possible that the urea pump is damaged, the urea pipeline is blocked, or the nozzle is blocked. Let the professionals deal with it.
