What is the purpose of adding urea to a vehicle?

[MaddoxDella]

The purpose of adding urea to a vehicle is to reduce nitrogen oxide compounds in the exhaust emissions, lower pollution levels, and enhance the vehicle's environmental friendliness. Consequences of not using urea: 1. Exceeding emission standards, causing environmental pollution; 2. Chemical substances in the vehicle's system may oxidize, leading to clogging of the urea injector and rendering the entire system inoperable; 3. Reduced vehicle performance. The functions of urea include: treating exhaust gases to reduce pollutants, optimizing engine performance, and improving fuel consumption. Reasons for urea warning light activation: 1. Low urea pressure, high urea consumption; 2. Insufficient power, excessively high or low urea consumption; 3. Instrument panel malfunction. Methods to resolve urea warning light alerts: 1. Replace the urea solution; 2. Replace the water heating valve; 3. Replace the urea pump and power supply module connector.
