Why Do Trucks Need to Add Urea?

[DelEli]

Trucks add urea to reduce the harmful gases produced by diesel vehicles during operation, thereby minimizing the environmental and human health impacts of vehicle emissions. Additional Information: During diesel engine operation, nitrogen oxides are generated, which are harmful to both the environment and human health. Urea contains a very high nitrogen content. When the vehicle detects the presence of these harmful gases, urea is automatically sprayed and mixes with the gases produced by the diesel engine. A chemical reaction then occurs, converting the harmful gases into water and nitrogen, both of which are harmless to humans and the environment, thus serving to protect the environment.
