Which Vehicles Require AdBlue?
2 Answers
Diesel vehicles require AdBlue, which is a diesel exhaust fluid used in SCR (Selective Catalytic Reduction) technology to reduce nitrogen oxide pollution in diesel exhaust. To meet annual emission inspection standards, diesel vehicles need to be equipped with an SCR system in their exhaust treatment. The AdBlue solution is used in the SCR system to treat nitrogen oxides in the exhaust. The consequences of not using AdBlue include: 1. Exceeding emission limits, causing environmental pollution; 2. Oxidation of chemicals in the vehicle's system, leading to clogged AdBlue injectors and rendering the entire system inoperable; 3. Reduced vehicle performance. The role of AdBlue is to treat exhaust gases, reduce pollutants in the emissions, and optimize engine performance and fuel consumption.
Automotive urea is primarily used for diesel vehicles equipped with SCR systems. Having driven several vehicles, I've noticed that large trucks and some diesel SUVs with high emission standards use it most frequently. The SCR system utilizes urea to break down nitrogen oxides in emissions, meeting environmental regulations. If not added, the dashboard will display a warning light, and in some cases, even limit the vehicle's power—this is most common in diesel engines meeting China IV standards or above. For example, heavy truck owners often need to replenish it periodically, typically at dedicated refill stations in gas stations. I remember one time when I forgot to add it, the vehicle felt off while driving, with slower acceleration, and later inspection revealed it was a urea issue. Timely replenishment ensures normal engine operation, reduces pollution output, and avoids the hassle of breakdowns. Paying attention to system alerts while driving is crucial for maintenance.
