Why Do Diesel Vehicles Need Urea Solution?

[Emmy]

Diesel vehicles add urea solution to reduce exhaust emissions and protect the atmospheric environment. The use of urea in vehicles is to convert harmful nitrogen oxides in the exhaust into nitrogen and water. The exhaust emitted by engines is extremely harmful to the atmospheric environment. With increasingly stringent environmental regulations, exhaust treatment systems have been developed to ensure compliance. The primary harmful substances in diesel exhaust are nitrogen oxides and particulates. The exhaust treatment system can reduce particulate emissions. Once urea is used in the vehicle, as long as the engine is running, the urea is injected into the exhaust treatment system, where it decomposes into ammonia gas at high temperatures.
