Why Do Diesel Vehicles Need to Add Urea?

Diesel vehicles add urea solution to reduce exhaust emissions and protect the atmospheric environment. Here is an introduction to urea solution: 1. Introduction: Automotive urea solution is a mixture of high-purity urea and pure water. 2. Description: Automotive urea is an essential product for heavy-duty diesel vehicles to meet the National IV emission standards. Automotive urea refers to a urea aqueous solution with a urea concentration of 32.5% and a solvent of ultra-pure water, with raw materials being specialized automotive urea and ultra-pure water. 3. Principle: Automotive urea must use Grade 1 ultra-pure water from the electronics industry. Due to the SCR catalyst carrier being highly susceptible to metal ion poisoning, which can lead to loss of catalytic effectiveness, automotive urea solution must use Grade 1 ultra-pure water from the electronics industry.

I've been driving a diesel car for many years, and adding urea is quite important. Why add it? Mainly to make the exhaust cleaner. Diesel cars are powerful and fuel-efficient, but their exhaust contains nitrogen oxides, which can cause smog and acid rain. Adding urea solution triggers a chemical reaction in the exhaust system, converting harmful gases into nitrogen and water vapor, which is much better for the environment. Current regulations are strict; if you don't add urea, the system will alert you, the car will lose power, and it may affect the annual inspection. I recommend that car owners develop the habit of checking the urea tank when refueling. Generally, it should be refilled every 5,000 kilometers, and a bucket costs around a hundred yuan, which isn't expensive. If you forget for a long time, it might clog the system, leading to costly repairs. Environmental protection starts with the details, and driving becomes more worry-free.

As a long-distance driver, I've found that adding urea to diesel vehicles is essential. Without it, the vehicle's power drops rapidly, and emissions exceed standards. The reason lies in the urea's interaction with the device in the exhaust pipe, known as SCR technology, which converts harmful nitrogen oxides into harmless substances. This not only complies with national environmental standards but also improves fuel efficiency. Once, I neglected to add it, the warning light came on, and the vehicle struggled to climb hills, costing me thousands in repairs. Now, before every trip, I check the urea gauge and top it up if it's below 30%. The cost is low, just a few yuan per liter, much cheaper than repairs. I advise everyone not to overlook this small detail; regular maintenance checks are sufficient.

Adding urea is a routine action when driving a diesel SUV. Not adding it will cause the exhaust treatment to fail. The core reason is that nitrogen oxides in the exhaust are harmful. After adding urea water, they react in the catalytic converter and transform into safe substances, protecting the environment. This system is simple and reliable, but you need to replenish the fluid on time. I usually add it at gas stations to avoid trouble.
