Car urea solution is clear, colorless, odorless, non-toxic transparent liquid, for selective catalytic NOx reductant. Can effectively reduce emissions of NOx and particulates automobile tail, reducing fuel consumption. To meet the China IV emission standards, the choice of SCR emission control technology vehicles must add urea solution as catalytic reducing agent, to ensure vehicle emissions standards. At present, China's heavy-duty diesel vehicles meet the Euro IV emission standard multi-use SCR emission control technology. SCR converter is the most important part of the urea solution vehicle, before it enters SCR converter has not been converted into the hot ammonia gas, ammonia and NOx within the catalytic converter to generate a chemical reaction converted to nitrogen and water, to reduce the emission of nitrogen oxides and particulates. Chinese name: Urea English name: urea Other names: urea Description: Car urea scientific name is diesel exhaust treatment fluid. Used in diesel engines. It is a technique used in the SCR, to reduce diesel exhaust in liquid nitrogen oxide pollution. Car urea scientific name is diesel exhaust treatment fluid. Used in diesel engines. It is a technique used in the SCR, to reduce diesel exhaust in liquid nitrogen oxide pollution. Its origin and the status quo: Due to national environmental protection departments to further reduce diesel emissions of nitrogen oxide pollutants discharge. Domestic commonly known as Euro IV standards. Engine manufacturers began using SCR technology (Selective Catalytic Reduction Technology selective catalytic reduction technology) to meet the requirements of the environmental protection department. Diesel Exhaust Fluid (domestic commonly known as: automotive urea, urea vehicle, automotive environmental urea), is a must to use SCR technology consumables. SCR systems include urea tank (loaded diesel exhaust treatment solution), SCR catalytic reaction tank. SCR system is running: When the discovery of nitrogen oxides in the exhaust pipe, urea tank is automatically ejected diesel exhaust treatment fluid, diesel exhaust treatment liquid and nitrogen oxide redox reaction in SCR catalytic reaction tank, generate no contaminated with nitrogen and water vapor is discharged. If you do not load diesel exhaust treatment liquid, or pure enough, or inferior quality will occur automatically slow down the vehicle's engine. Meanwhile, the quality of shoddy treatment of diesel exhaust fluid can contaminate the SCR catalyst in the catalytic reaction tank, causing serious consequences.

Heavy-duty diesel vehicles in long-distance buses, marine diesel and other brand cars with urea solution is a heavy-duty diesel engine exhaust gas abatement material used, the role of the device through the SCR selective catalytic reduction, the vehicle exhaust emissions of nitrogen oxides (NOx) Hydrogen and oxygen are reduced to reduce the emission of nitrogen oxides and particles, and to reduce air pollution. SCR technology is the most suitable for heavy-duty trucks and buses of Euro IV and Euro IV exhaust emission solutions, CommScope sinks dimensional vehicle urea solution is your best choice.
