Shangchun has passed the "bench test" and meets the original factory calibration standards. The water molecule clusters are smaller and can break the covalent bonds of soluble harmful substances in urea solution. The solution does not contain crystallization inducers and has good atomization effect, effectively protecting the vehicle's SCR system, reducing maintenance probability and parts replacement frequency, and maintaining the vehicle's performance as new for a long time.
