Can a Diesel Vehicle Continue to Run Without Urea?
2 Answers
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.
I've been driving a diesel car for several years, and it's best not to continue driving if the urea runs out. Adding urea is for emission control, and the system is called AdBlue. Without it, the car's warning light will come on. If you keep driving, the engine power will be limited, making it difficult to accelerate, which could be dangerous when overtaking on the highway. Emissions will increase, polluting the air and harming the environment. The SCR components are also prone to damage, and repairs can be extremely expensive. You can usually buy urea in barrels at gas stations—just top it up to solve the problem. It saves money, hassle, and ensures safety. Don’t overlook this small tip; checking the dashboard reminders before driving is essential.
