What is the role of urea in vehicles?

[DelConnor]

The functions of automotive urea solution are as follows: 1. Automotive urea solution is used to reduce nitrogen oxides in vehicle exhaust, thereby lowering the pollution level of the emissions. 2. Automotive urea solution is a colorless, transparent, and clear liquid with a concentration between 31.8 and 33.2. Currently, the commonly used automotive urea solution consists of 32.5% high-purity urea and 67.5% deionized water. 3. Automotive urea solution is crucial for reducing pollutant emissions from diesel vehicles. It is a urea-based chemical reagent, formed by mixing high-purity urea with deionized water to create a 32.5% concentration solution. The application of automotive urea solution in the SCR (Selective Catalytic Reduction) system is key to enabling engine exhaust emissions to meet National IV and higher emission standards.
