What are the reasons for a vehicle not consuming urea?

[LeVera]

Vehicle not consuming urea may be due to the SCR system not functioning properly. Below are the hazards of not using urea: 1. Environmental pollution: Diesel vehicles without urea can have an extremely negative impact on the ecological environment, and this is also prohibited by national laws and regulations. 2. Damage to the SCR injection system: If urea is not used for a long time, the nozzles, pipelines, and urea pump in the SCR system may crystallize and clog, or be damaged by high temperatures. 3. Reduced power: This is not a direct result of not using vehicle urea, but rather because when the engine's electronic control system detects no urea injection and excessive exhaust pollution, it will forcibly limit the engine's torque output.
