What is the function of the urea tank?
1 Answers
The function of the urea tank is to reduce the liquid containing nitrogen oxide pollution in the exhaust gas of diesel vehicles. The urea tank is a urea storage tank, also known as a urea canister, which contains urea solution and is mainly used in trucks and buses. After the vehicle exhaust passes through the urea tank, the emissions can meet the National IV standard. Principle of the urea tank: According to the National IV and Euro IV emission standards implemented in 2008, urea aqueous solution is required in the diesel engine emission reduction system, and this urea tank is used to store the urea aqueous solution. To reduce the emission of harmful NOX gases from vehicles, the SCR (Selective Catalytic Reduction) technology is widely adopted internationally. The principle of SCR exhaust treatment is to use urea aqueous solution to react with nitrogen oxides (NOX), producing non-polluting nitrogen and water. Material and structure: The tank body is made of high-density polyethylene material resistant to urea corrosion. The tank is formed as a whole through rotational molding, making it sturdy and durable, available in black or white, meeting safety requirements. The accessory parts are made of reasonable materials to meet the design requirements of the SCR system. Advantages of the urea tank: It can protect the environment and avoid harm. After adding urea, the produced water and nitrogen are non-toxic and harmless.
