Your Car "Urine" Can Bring Harm To Poor Quality Urea

Dear friends of Guosi vehicle users: how much do you know about urea products? What harm will the use of inferior urea bring to your car? How much loss? In order to spend less, the users of Guosi vehicles buy cheap urea in the market. These practices seem to reduce the vehicle cost. In fact, there are great irrationalities, and even let you spend more money.

Damage 1: damage to urea of pumppoor quality urea Urine

In fact, the production standard of vehicle urea is strict, which is composed of 32.5% high-purity urea and 67.5% deionized water. In order to reduce the production cost, some enterprises use ordinary water instead of deionized water, but the vehicle urea produced in this way can not meet the use requirements and belongs to unqualified products. The content of impurities in the urea solution produced with non deionized water will also exceed the standard, block the filter, urea solution transmission pipeline and nozzle, reduce the atomization effect of SCR system, and excessive impurities will even damage the urea pump.

Damage 2: damage of urea nozzle Urine

The urea nozzle is located in the exhaust pipe and is in a high-temperature environment for a long time. When it works, it is cooled through the circulation of urea solution. If the cooling effect of urea solution is not obtained, the urea nozzle is easy to be damaged.

Damage 3: the metering pump is damaged

If the concentration does not meet the standard, the emission will exceed the standard, which will eventually be reflected in the immediate reduction of engine torque and vehicle weakness, which will increase the freezing point of the solution. Under cold conditions, the metering pump will be frozen.

Case: the user of one country and four vehicles in Chongqing found that the OBD fault light was abnormal. It was diagnosed that the urea nozzle was blocked. It was detected that the urea product did not meet the standard. The NOx sensor and the original urea were replaced, resulting in a direct loss of 2750 yuan. The user lamented that the use of counterfeit products is not worth the loss.

In short, the use of unqualified urea solution will cause damage to the aftertreatment system components such as urea pump, nozzle and catalyst, which will bring you considerable losses. Therefore, you car owners should not lose big things for small things. You should choose pure vehicle urea solution.
