Description

[0002] Exhaust treatment fluid is a liquid used to reduce nitrogen oxide pollution in automobile exhaust. It is mainly divided into two types: urea solution and ammonium sulfate solution, both of which can effectively reduce automobile exhaust emissions. The most basic function of exhaust treatment fluid is to convert nitrogen oxides in automobile exhaust into harmless nitrogen and water to achieve the purpose of energy saving and environmental protection. For urea solution, its main components are urea, water and additives. In heavy-duty diesel vehicles, urea solution is usually used as automotive urea and is an important product that meets national emission standards. In vehicles, it can react with nitrogen oxides in exhaust gas to reduce nitrogen oxide emissions, thereby protecting the environment. Exhaust treatment fluid will produce more foam during the production process.
