When a truck runs out of urea, it faces a series of problems. Firstly, the torque of the truck will be limited, resulting in insufficient power and making driving feel particularly strenuous. Additionally, the emission of nitrogen oxides from the truck will be more severe than even the National Standard III, causing significant pollution to the environment.
In the long run, the lack of urea can lead to crystallization or high-temperature damage in the urea pump, nozzles, and pipelines of the truck, resulting in relatively high maintenance costs. Therefore, timely replenishment of urea solution is essential to avoid these issues.
The role of urea in trucks is crucial
By adding urea, the content of nitrogen oxides in the exhaust gas can be reduced, thus minimizing environmental pollution. This is because the urea solution chemically reacts with nitrogen oxides in the exhaust gas, ultimately converting the exhaust into harmless nitrogen and water.
Although trucks can still operate without urea, it is necessary to replenish urea solution as soon as possible. There is no exact data on the specific distance a truck can travel without urea, but the lack of urea will limit the torque of the vehicle, resulting in insufficient power and making driving very difficult. Therefore, replenishing urea solution promptly can restore the truck to its normal operating condition.
Torque can be considered as the force of a vehicle, and when torque is limited, the vehicle loses power. This will lead to pressing the accelerator pedal harder to increase diesel consumption, and in the case of prolonged urea deficiency, the engine of the vehicle will automatically slow down.
In addition to affecting the vehicle itself, long-term urea deficiency can also damage engine components such as urea pump nozzles, pipelines, etc. These parts are susceptible to crystallization blockage or high-temperature damage, affecting the normal operation of the truck and increasing maintenance costs.
