Do National V Standard Pickup Trucks Consume Urea?
2 Answers
National V standard pickup trucks do not consume urea. General reasons why National V engines do not consume urea: Check if the urea nozzle is crystallized and blocked. The urea nozzle is a common fault area and often experiences crystallization blockages. Verify if the control unit has power supply settings for the nozzle. Generally, damage to the power supply wiring can lead to open circuits, short circuits, or broken circuits, affecting the normal operation of after-treatment components. Prolonged urea combustion in the engine can easily cause system damage. This should be taken seriously, as prolonged combustion can lead to exhaust pipe blockages, reducing engine transmission efficiency, inevitably increasing fuel consumption, and potentially damaging the SCR system. Difference between consuming and not consuming urea: Urea consumption is aimed at reducing nitrogen oxide emissions. To achieve better energy savings and emission reductions, adding urea ensures that the exhaust emissions meet national standards.
Most China V standard pickup trucks require urea injection because the China V emission standards mandate diesel vehicles to control nitrogen oxide emissions, commonly achieved by equipping an SCR system that uses urea solution for treatment. I understand this system functions like a small filter inside the vehicle—when the engine runs, urea is injected into the exhaust system, where a chemical reaction converts harmful gases. However, urea is not a fuel and does not participate in the combustion process. As an owner, I've found that daily use requires regular urea refills; otherwise, the system warning light will illuminate, and it may even limit speed for protection. When purchasing a vehicle, it's advisable to check the configuration manual to confirm if it has SCR functionality. Also, ensure you use qualified urea brands to avoid nozzle clogging or catalytic converter damage. While driving, monitor dashboard alerts and refill the urea tank promptly—my vehicle typically needs a refill every few thousand kilometers.
