What is the function of urea solution for heavy vehicles?

The purpose of using urea in vehicles is to reduce exhaust emissions. The function of vehicle urea and national policy regulations are as follows: Function of vehicle urea: The main purpose of adding urea to vehicles is to reduce exhaust emissions, as the exhaust from diesel engines mainly consists of nitrogen oxides and carbon particles. National regulations clearly stipulate: Because vehicle exhaust emissions pose significant hazards to both humans and the environment. Therefore, the National IV standard implemented in China in 2008 stipulates that diesel vehicles' emission reduction systems must use vehicle urea to reduce the hazards of vehicle exhaust.
The role of diesel exhaust fluid (DEF) is really crucial. I've dealt with many diesel vehicles, and it's primarily used in the exhaust system to treat emissions. This fluid is called AdBlue or automotive urea, and diesel vehicles rely on it to reduce nitrogen oxide pollution. With strict environmental regulations nowadays, failing to use it leads to excessive exhaust emissions, harming the environment—like worsening smog and affecting health. Many cities inspect exhaust emissions, and lacking DEF can result in fines or even vehicle impoundment. Specifically, it works through the SCR system, where DEF is injected into the exhaust pipe to react with the gases, converting harmful emissions into harmless nitrogen and water. I've used it and found that regular top-ups make the vehicle run more eco-friendly, avoiding repair hassles. It's not just a regulatory requirement but also a responsibility to our planet. I advise everyone not to overlook it—check the DEF tank before each refuel. It's a simple, low-cost practice that significantly improves air quality.
I deal with AdBlue in the cab every day—it's just a small liquid tank used for engine exhaust. Its main function is to treat diesel vehicle emissions, turning black smoke into clean gas. Without it, the vehicle's acceleration can suffer, and even the engine warning light may come on. I remember a friend who forgot to refill it and ended up with an emissions violation, fined hundreds of dollars and delaying deliveries. It's pretty practical—I’ve made it a habit to grab a bottle at the gas station and top it off to keep the level full. Designed to help the SCR system work, it reduces roadside exhaust pollution. The benefits are plenty: saving on repair costs, protecting health, especially in city traffic jams. Nowadays, most heavy-duty trucks rely on it, and I always carry a spare on long hauls. A small investment for big returns, ensuring peace of mind on the road.
