Handan vehicle manufacturers, wholesale car urea water urea solution (AdBlue) is used without any other additives and high purity urea solution prepared pure water, the solution of urea content of 32.5% (by mass). Most domestic and foreign manufacturers of heavy-duty diesel engines using SCR (Selective Catalytic Reduction) technology to meet Euro IV, Euro Ⅴ vehicle emission standards. Choose SCR technology vehicles must add urea solution as catalytic reducing agent, the vehicle emissions standards. Diesel engine exhaust treatment liquid (commonly known as: automotive urea, urea car, car environmental urea), in China and Europe called AdBlue, in the Americas called DEF, in Brazil called ARLA32 AdBlue is a composition of 32.5% high. high purity urea and 67.5% pure deionized water was transparent liquid, with a touch of ammonia odor. If spilled, evaporation and crystallization. AdBlue is used with SCR (Selective Catalytic car after reducing exhaust treatment) car systems, trucks, buses and heavy-duty off-road diesel engine vehicles is SCR technology must be used to consumables, together with the SCR catalyst will harmful nitrogen oxide emissions from diesel engines is converted into harmless water vapor and nitrogen. The main component of the SCR system includes a catalyst, AdBlue injection device, AdBlue and AdBlue container dose controller. Almost all of Europe, the United States and Asia, including China's heavy-duty vehicle manufacturers for vehicles equipped with selective catalytic reduction system and with AdBlue fluid, in order to meet the new emission standards for nitrogen oxides (such as Euro IV, Euro V) AdBlue and SCR technology under the joint action, to optimize engine performance and fuel consumption, reduce diesel fuel consumption can be as high as 6%, significantly lower costs. The average consumption of AdBlue is generally 5% of diesel consumption, consumption highway driving is approximately 1.5 liters per 100 kilometers. AdBlue can be used only in combination configuration engine SCR system, because it is neither fuel nor fuel additive. AdBlue perform in line with ISO22241, DIN70070 standards within CEFIC regulations and to ensure the effective operation of the SCR system. AdBlue is not harmful to the environment and is classified as low-risk transportable liquid.
