Diesel exhaust treatment fluid 10kg Product Name: Diesel Exhaust Fluid (vehicles with urea solution) Packing: 10kg × 2 bucket car urea scientific name is diesel exhaust treatment fluid. Applied to a diesel engine. It is a technique used in the SCR, diesel exhaust to reduce nitrogen oxides in contaminated liquids. Its composition is 32.5% and 67.5% of high-purity urea deionized water. Its origin and status quo: As national environmental protection department to further reduce diesel emissions of nitrogen oxide pollutants discharge. Domestic commonly known as Euro IV engine manufacturers began using SCR technology (Selective Catalytic Reduction Technology selective catalytic reduction) to meet the requirements of environmental protection department. Diesel Exhaust Fluid (domestic commonly known as: automotive urea, urea vehicle, automotive environmental urea), is to use SCR technology consumables must include urea SCR system tank (diesel exhaust treatment fluid loading), SCR catalytic reaction tank. SCR system is running: When the discovery of nitrogen oxides in the exhaust pipe, the urea tank is automatically ejected diesel exhaust treatment fluid, diesel exhaust treatment fluid and nitrogen oxide redox reactions SCR catalytic reaction tank, generate no nitrogen and water vapor exhaust pollution. If you do not load the diesel exhaust treatment fluid, or pure enough, or inferior quality will occur automatically slow the vehicle engine. Meanwhile, shoddy quality diesel exhaust treatment fluid can contaminate the SCR catalyst in the catalytic reaction tank, resulting in serious consequences.
