What is the function of urea in vehicles?
3 Answers
Automotive urea is used to convert nitrogen oxides in vehicle exhaust into harmless nitrogen and water, which is energy-saving and environmentally friendly, enabling the vehicle to meet the national exhaust emission standards. It is generally used in diesel vehicles. Simply use a filling tube to pour the automotive urea solution into the urea tank on the vehicle. Here is some information about automotive urea: 1. Automotive urea is a liquid used in SCR (Selective Catalytic Reduction) technology to reduce nitrogen oxide pollution in diesel vehicle exhaust. 2. Its composition is 32.5% high-purity urea and 67.5% deionized water. 3. When selecting urea solution, it is advisable to choose high-quality products to control vehicle maintenance costs.
In my daily driving of a diesel vehicle, I learned that the urea in the car is mainly used to reduce exhaust pollution. The emitted exhaust contains nitrogen oxides, which are harmful to the environment and health. After adding urea, it reacts in the SCR system to produce ammonia gas, which then neutralizes those harmful gases into harmless nitrogen and water. This not only meets emission standards but also keeps the air clean. If urea is not added, the vehicle will automatically limit speed or even stop. I once neglected this and ended up stranded on the road, delaying my journey. I recommend developing the habit of regularly adding AdBlue, whether at service stations or by keeping a simple DIY kit. This not only saves money and avoids high repair costs but also fulfills environmental responsibilities—a small bottle brings significant benefits. Remember to maintain accurate concentration and use genuine products to ensure system stability.
As an automotive technician, I frequently deal with urea-related issues. Its core function is to control emission pollution. In the SCR system, urea is injected to decompose into ammonia, which neutralizes nitrogen oxides in the exhaust, converting them into safe substances like nitrogen and water. Not adding urea can lead to reduced engine power or trigger warning faults, resulting in costly repairs. Common problems include urea pump blockages or low fluid levels. I recommend car owners check the urea tank monthly and refill with pure AdBlue at reliable stations to prevent freezing in winter and evaporation in summer. Timely maintenance extends component lifespan, saves costs, and avoids fines for exceeding emission standards. Don't overlook these critical details.
