Can a Diesel Vehicle Continue to Run Without Urea?

[Jade]

Diesel vehicles can continue to run without urea, but it is necessary to replenish it as soon as possible. If a diesel vehicle operates without urea, its nitrogen oxide emissions will be even worse than those of a National III standard vehicle. Prolonged operation without urea can easily lead to crystallization, clogging, or high-temperature damage in the urea pump nozzle, pipelines, and urea pump, all of which are expensive to repair. Below is additional information: Function of automotive urea: The most basic function of automotive urea solution is to convert nitrogen oxides in vehicle exhaust into harmless nitrogen and water, saving energy and protecting the environment, thereby helping the vehicle meet national exhaust emission standards. Precautions: Automotive urea must use ultra-pure water of electronic grade. Since the SCR catalyst carrier is highly susceptible to metal ion poisoning, which can render it ineffective, automotive urea solution must use ultra-pure water of electronic grade.
