What is AdBlue? Do diesel vehicles in China need to add it?

[LiamLynn]

AdBlue is a diesel exhaust fluid, also known as automotive environmental urea. When the AdBlue light illuminates on the combination meter, it is necessary to check and replenish the urea. Some vehicles may fail to start after running out of urea. Relevant information about gasoline is as follows: 1. Introduction: Gasoline is a volatile, flammable hydrocarbon mixture liquid obtained from petroleum through fractionation and cracking, used as fuel. It appears as a transparent liquid, is flammable, and has a distillation range of 30°C to 220°C. 2. Important characteristics: The key properties of gasoline include volatility, stability, anti-knock quality, corrosiveness, and cleanliness.

AdBlue is an environmentally friendly liquid used in diesel vehicles, primarily consisting of a urea solution, designed to reduce harmful nitrogen oxide emissions from exhaust. I've been driving a diesel SUV for several years and frequently encounter the need to refill this solution. It operates through a system called SCR (Selective Catalytic Reduction), where it mixes with exhaust gases during emission, converting pollutants into harmless nitrogen and water. In China, many new diesel vehicles like trucks and SUVs require AdBlue, especially under the National V and VI emission standards that mandate SCR technology. Without it, the vehicle might not run properly or trigger warning alerts. I recommend regularly checking the AdBlue level in your vehicle—a single refill can last several months and is usually available at gas stations. Though it may seem insignificant, AdBlue plays a crucial role in maintaining clean air, significantly reducing pollution, particularly in congested urban areas.

As a truck driver, I'm all too familiar with AdBlue—it's an absolute necessity for diesel vehicles. Before every trip, I have to check if there's enough in the tank. Typically, it needs a refill every 1,000 to 2,000 kilometers, otherwise the dashboard warning light comes on. In China's transportation industry, national standards mandate that most diesel vehicles must use this fluid because it purifies exhaust gases, preventing nitrogen oxide pollution. The consequence of skipping it is straightforward: the vehicle will enter limp mode or even shut down, disrupting work. I remember once forgetting to refill during a long-haul trip—I nearly got stranded, but luckily service stations always stock it. In short, using AdBlue has become as routine as refueling—it's both eco-friendly and practical.

AdBlue is essentially a urea solution that helps diesel vehicles reduce emissions. From an environmental perspective, this is particularly important in China because the new national standards are stricter. Without it, vehicles can't meet the standards, and pollution will worsen urban smog. The working principle is simple: after being added to the vehicle, it works with the control system to break down harmful substances in the exhaust. I recommend everyone pay attention to regular refills—don't wait for the warning light to top up, as it saves both money and hassle. Although it's not as frequent as gasoline refills, it needs to be done every few months; otherwise, it can affect driving safety.
