A semi-trailer requires urea to be added. The semi-trailer adopts urea scr technology, which injects urea into the exhaust emissions of diesel engines, reacts with nitrogen oxides, and converts them into nitrogen and water vapor, thereby reducing exhaust emissions. This technology not only meets environmental requirements, but also reduces the emissions of nitrogen oxides and particulate matter, protecting the environment and human health.
The urea scr technology converts harmful gases into harmless nitrogen and water vapor through catalytic reduction reactions. Specifically, urea reacts with water at high temperatures to produce ammonia (nh3), which then reacts with nitrogen oxides to produce harmless nitrogen and water vapor, thereby reducing the emission of harmful gases.
