Detailed Product Description: | Zhengzhou vehicle urea Which is better? Supply Zhengzhou vehicle urea urea thousand net vehicle is ideal for four diesel engines meet the national emission standards for cars, trucks, buses, bus vigorously Supply Zhengzhou vehicle urea Which is better? Supply Zhengzhou vehicle urea. SCR is the best choice of emissions. Currently existing Chaiyou Guo standard GB19147-2009 claim sulfur ≤350ppm, and ECR-DOC technology require oil sulfur content below 10ppm, and therefore to promote conditions in China has temporarily. SCR may be resistant to 350ppm sulfur oil, therefore the promotion of the technical basis. As a result of the country's four-engine SCR technology better fuel economy than the EGR technology, small changes to the engine, fuel and oil requirements are lower, with the advantage of continuity in the technical upgrade, SCR catalytic converter catalytic converter durability and there is no blockage The risk, therefore SCR technology is the most suitable for China's heavy-duty diesel emissions reduction technology roadmap. ?? Thousand net vehicle urea concentration of 32.5% ultra-pure water and the solvent is an aqueous urea solution, the production of raw materials for urea crystals and ultra-pure water, the key point is that the purity of raw materials. From the production process, although the car with urea raw material purity requirements than the general industrial demand, but currently the process already meet the actual application requirements. Car urea production process is not sufficient to build a high barrier to entry vehicle urea solution is used without any other additives and water together with high-purity urea solution prepared, in the solution of urea content of 32.5% (mass fraction). Most heavy-duty diesel engine manufacturers at home and abroad using the SCR (Selective Catalytic Reduction) technology to meet Euro IV, Euro Ⅴ vehicle emission standards. Select SCR technology vehicles must add urea solution as a catalyst reductant, the vehicle emissions standards. ??? Thousand net urea is ideal for car diesel engines meet the national IV emission standards for cars, trucks, buses, bus vigorously Supply Zhengzhou vehicle urea Which is better? Supply Zhengzhou vehicle urea. |
