Can a Diesel Vehicle Continue to Run Without Urea?

[AngeloLynn]

Diesel vehicles can continue to run without urea, but it is necessary to replenish it as soon as possible. If a diesel vehicle lacks urea, its nitrogen oxide emissions will be even worse than those of a National III standard vehicle. Prolonged absence of urea can easily lead to crystallization blockages or high-temperature damage in the urea pump nozzle, pipelines, and the urea pump itself, and repairing these parts can be very expensive. For trucks without urea, the emission light on the dashboard will illuminate, restricting torque and causing insufficient power, making the vehicle feel particularly sluggish. Crystallization Issue: It might be a urea crystallization problem. If the vehicle also exhibits symptoms like weak acceleration or white smoke from the exhaust pipe, professional equipment should be used to clean the urea crystallization inside the exhaust pipe. Malfunction Occurrence: If the urea pump or sensor malfunctions and the engine torque is restricted, with the RPM unable to exceed 1800 revolutions per minute, the urea pump and sensor need to be replaced.
