What is the purpose of using urea in vehicles?
2 Answers
The primary purpose of using urea in vehicles is to purify exhaust emissions and reduce nitrogen oxide emissions, typically used in diesel vehicles. There is a dedicated urea tank in the vehicle, and urea is consumed as the vehicle operates. The functions of using urea in vehicles are as follows: 1. Optimize engine performance and fuel consumption, reducing diesel consumption by up to 6%, significantly lowering costs. 2. React with nitrogen oxides in the exhaust to reduce nitrogen oxide emissions. 3. If diesel exhaust fluid (vehicle urea) is not loaded, or if the purity is insufficient, or if the quality is inferior, the vehicle's engine will automatically decelerate. Inferior quality diesel exhaust fluid can contaminate the catalyst in the SCR catalytic reaction tank, leading to serious consequences.
People who drive diesel vehicles know that urea is mainly used to reduce harmful substances in exhaust gases. It is added to the exhaust pipe through a system, and its function is to convert the dirty stuff produced by the engine into clean gases before they are released. If you don't add urea, the vehicle might limit your speed or turn on a warning light, making it impossible to drive normally. When I refuel, I also buy a can of AdBlue and add it to the vehicle—it feels like part of routine maintenance. Doing this makes the exhaust smell less foul and keeps the environment cleaner. It's actually quite simple, but you need to check it regularly and not wait for a warning to take action. Remember, not adding urea not only harms the environment but may also cause engine problems, leading to higher fuel consumption and costly repairs.
