What are the consequences of not adding urea to heavy-duty vehicles?

[FelicityMarie]

The drawbacks of not adding urea to heavy-duty vehicles need to be discussed from three aspects: the vehicle itself, environmental protection, and traffic law enforcement. Here are the specific details: Vehicle itself: China V vehicles must add urea. If not added, it may result in the vehicle being torque-limited, unable to accelerate, lacking power, and consuming more fuel. Environmental protection: The government has introduced new environmental policies focusing on the treatment of diesel vehicle exhaust. Urea, as a mandatory additive, is used to eliminate nitrogen oxides in the exhaust, reducing the emission of substances harmful to the atmosphere. Therefore, not adding urea will cause pollution to the atmosphere. Traffic law enforcement: Nowadays, many regions have exhaust emission testing points, similar to speed detection. If excessive exhaust emissions are detected, the vehicle will be penalized.
