SCR Urea is a necessary product for heavy-duty diesel vehicles to meet the National IV emission standard. Wholesale automotive urea is an aqueous urea solution with a urea concentration of 32.5% and a solvent of ultrapure water, with raw materials of urea crystals and ultrapure water. Heavy trucks, buses and other diesel vehicles to meet the national emission standards, in the exhaust treatment will have to choose a suitable SCR system, and this system must use the urea solution for the treatment of nitrogen oxides in the exhaust gas. Therefore, the SCR Urea solution has become a necessary product for heavy-duty trucks and buses to meet the National IV emission standards.

 

SCR is the optimal choice for emission reduction in China. The current domestic diesel national standard GB19147-2009 requires sulfur content 350ppm, while ECR-DOC technology requires oil with sulfur content below 10ppm, so it does not have the promotion conditions in China for the time being. SCR is resistant to 350ppm sulfur-containing oil, so it has the technical basis for promotion. SCR technology is the most suitable technology for heavy-duty diesel vehicles in China because of its better fuel economy than EGR technology, less engine modification, lower fuel and oil requirements, advantages in technology upgrade continuity, good durability of SCR catalytic converter and no risk of catalytic converter blockage.
