Why Do Large Vehicles Need to Add Urea, and What Role Does It Play?

[RobertAnn]

Adding urea to large vehicles is to reduce harmful nitrogen oxides in the exhaust into nitrogen and water, which can decrease nitrogen oxide compounds in vehicle emissions, reduce pollution, and improve the environmental friendliness of the vehicle. The consequences of not using urea include: 1. Exceeding emission standards, causing environmental pollution; 2. Oxidation of chemicals in the vehicle system, leading to clogging of the urea nozzle and rendering the entire system useless; 3. Reduced vehicle power. The role of urea is: to treat exhaust gases, reduce pollutants in the emissions, and optimize engine performance and fuel consumption. Reasons for urea warning light activation include: 1. Urea pressure too low, high urea consumption; 2. Insufficient power, urea consumption too high or too low; 3. Instrument panel malfunction. Methods to eliminate urea warning light alerts are: 1. Replace the urea solution; 2. Replace the water heating valve; 3. Replace the urea pump and power supply module plug.
