What is the purpose of urea solution for trucks?
1 Answers
The most basic function of automotive urea solution is to convert nitrogen oxides in vehicle exhaust into harmless nitrogen and water, which is energy-saving and environmentally friendly, enabling the vehicle to meet the national exhaust emission standards. Through the intelligent control of the SCR system, when the urea solution in the mixer storage tank is insufficient, the vehicle will not start. To ensure normal operation, an adequate supply of urea solution should be maintained. Below is an introduction to automotive urea: 1. Origin: Automotive urea solution was first used in Europe, known as Adblue, in North America as DEF (Diesel Exhaust Fluid), and domestically as automotive urea solution or "automotive denitrification agent." However, it is now generally referred to as "automotive urea" in China. 2. Function: Automotive urea solution is key to reducing pollutant emissions from diesel vehicles. It is a urea-based chemical reactant, composed of high-purity urea and deionized water, forming a 32.5% concentration solution. The application of automotive urea solution in the SCR system is crucial for engine exhaust emissions to meet the National IV and higher emission standards.
