What will happen to the five domestic trucks if they continue to drive without urea solution?

1, without the influence of urea island. Pollution to the environment, in order to give consideration to the performance of particle emission, the SCR car of Guosi Company is marked with high lead angle. If urea is not sprayed, the emission of nitrogen oxides is more serious than that of the third company of China, and it is better to cause less harm to future generations. If there is no urea circulation for a long time, the nozzles, pipelines and urea pumps are easy to crystallize, block or be damaged at high temperature, and it is very expensive to repair the car. If you do it according to the regulations, if you don't add urea, add water or mix urea with water, it will light the discharge lamp and limit the torque. This car is boring. Of course, if your car factory itself is illegal, it will not be reported. It has no influence on the life and performance of the engine itself, catalyst carrier, exhaust temperature and NOx sensor.

2, because the national implementation of the national four is mandatory emission standards. Therefore, the manufacturer must input the sensing data of urea sensor into the computer control panel when producing the fourth engine. Once the data from the sensor shows that urea has been consumed or there is no urea, the control panel will control the working state of the engine and make the engine look weak. If you have no strength, you have to increase the throttle, and the fuel consumption is naturally high. Even so, the engine can't output power at full load. This is only a means of national enforcement, otherwise, who will add urea and spend more money.

3. The vehicle urea solution is a colorless and transparent clear liquid with a concentration of 3 1.8%-33.2%, which is used to reduce nitrogen oxides. Vehicle urea solution was first used in Europe, called Adblue, in North America called DEF (diesel tail gas liquid), and in China called vehicle urea solution or "vehicle denitration agent".

4. The most important point of National Fourth is to increase the urea solution for vehicles. Since the promotion of National Day 4 in China at the beginning of the year, the high-frequency word urea solution for vehicles has been widely discussed. For card friends, this term is not new. However, there are still misunderstandings and misunderstandings about urea solution for vehicles. The following small series will make a systematic summary again, hoping to help you better understand.
