What is Automotive Urea?
3 Answers
Automotive urea is a liquid used in SCR technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. Its composition consists of 32.5% high-purity urea and 67.5% deionized water. Additional information: 1. As environmental protection departments in various countries proposed further reduction of nitrogen oxide pollutants emitted by diesel engines (commonly known as the Euro IV standard in China), engine manufacturers began using SCR technology to meet environmental requirements. Diesel exhaust fluid is a necessary consumable in SCR technology. 2. Failure to load diesel exhaust fluid, or using fluid with insufficient purity or inferior quality, will cause the vehicle engine to automatically decelerate. Moreover, inferior quality diesel exhaust fluid can contaminate the catalyst in the SCR catalytic reaction tank, leading to serious consequences.
Automotive urea, commonly known as AdBlue, is a specialized liquid used in diesel vehicles. As an enthusiast with years of driving experience, I enjoy sharing this knowledge. Its primary purpose is to reduce exhaust emissions, particularly within the exhaust pipe system. When diesel fuel burns, it produces harmful nitrogen oxides. By injecting urea solution through a technology called SCR (Selective Catalytic Reduction), these pollutants are converted into harmless water and nitrogen gas. I've seen many people neglect it, but the consequences can be severe—such as reduced engine power or fault codes—outweighing any perceived benefits. Nowadays, many regions mandate its use due to strict environmental regulations. When purchasing a new car or servicing your vehicle, it's advisable to check the urea tank and top it up with a few liters periodically. It's affordable and environmentally friendly. Maintenance is straightforward—just don't overlook it.
I've been driving a diesel pickup truck for several years, and AdBlue is a daily necessity. It's that blue liquid stored in a small tank at the back of the vehicle. Every time I go to the gas station, I grab a bottle and top it up, roughly every two to three months. If you don't add it, the engine will limit its RPM, making the drive feel sluggish, which is quite a hassle. Cost-wise, a bottle costs a few dozen yuan and lasts a long time, making it more economical than gasoline. I remember a friend once forgot to add it, and the car's warning light came on, costing several hundred yuan to fix. This stuff helps reduce vehicle emissions, making the exhaust cleaner and better for the air. I recommend everyone get into the habit of using it.
