What is the function of urea solution for heavy trucks?

[MacIsla]

The function of urea solution for heavy trucks: It is used to reduce nitrogen oxides in vehicle exhaust, thereby lowering the pollution level of vehicle emissions. The urea solution for vehicles is a colorless, transparent, and clear liquid with a concentration between 31.8%-33.2%. Currently, the urea solution used in vehicles is generally composed of 32.5% high-purity urea and 67.5% deionized water. Below is an introduction to vehicle urea: 1. Vehicle urea solution was first used in Europe, where it is called Adblue. In North America, it is referred to as DEF (Diesel Exhaust Fluid), and in China, it is known as vehicle urea solution or "vehicle denitrification agent." However, it is now commonly referred to as "vehicle urea" in China. 2. Vehicle urea solution is key to reducing pollutant emissions from diesel vehicles. It is a urea-based chemical reactant, made by mixing high-purity urea with deionized water, forming a solution with a concentration of 32.5%. The application of vehicle urea solution in SCR systems is crucial for achieving National IV and higher emission standards for engine exhaust.
