Do China IV Diesel Vehicles Require Urea?

[Jenkins]

China IV diesel vehicles require urea. Urea is essential: With the improvement of national emission standards, vehicle urea has become a necessary consumable, just like engine oil and lubricants today. Urea standards: In China, qualified urea solution is the standard, generally composed of 32.5% ultra-pure urea and pure water to synthesize NOX. The urea solution reacts with NOX to produce nitrogen, oxygen, and water, thereby reducing nitrogen oxide emissions. This method is applicable to every Euro IV and Euro V diesel engine SCR system. Hazards of inferior urea: The power and fuel consumption of diesel vehicles are affected by urea. If a diesel vehicle does not have an exhaust treatment device or uses inferior products, it will cause the vehicle's engine to automatically decelerate and also affect the catalyst in the SCR catalytic reaction tank.
