What is AdBlue? What is its use for vehicles?

AdBlue and its functions are as follows: 1. Introduction: AdBlue, also known as Diesel Exhaust Fluid (DEF), is a consumable necessary for the SCR (Selective Catalytic Reduction) system. 2. Function: The primary use of AdBlue in vehicles is to reduce harmful nitrogen oxides (NOx) in the exhaust into nitrogen and water. Additional relevant information: 1. Composition: AdBlue is a colorless, transparent liquid with a concentration between 31.8%-33.2%, primarily composed of 32.5% high-purity urea and 67.5% deionized water. 2. Principle: AdBlue works in conjunction with the SCR system. When a diesel engine expels combustion gases from the combustion chamber, the controller receives a signal, prompting the urea pump to extract AdBlue from the urea tank and inject it into the exhaust pipe via a nozzle. The AdBlue then mixes uniformly with the exhaust gases before passing through the SCR-specific catalytic filter, effectively filtering and removing the main diesel engine pollutants, NOx, and particulates.
As a regular vehicle owner, I've been using AdBlue for several years. It's a liquid that's added to a dedicated tank in diesel vehicles, primarily for exhaust treatment to reduce pollution. When I drove a truck, I had to refill it regularly; otherwise, the system would throw an error, which was really annoying. Functionally, AdBlue works in the exhaust system to convert harmful nitrogen oxides into water and nitrogen, protecting the environment and avoiding fines. At first, I didn't understand this stuff and thought it was just an additive. Later, I realized that without it, the vehicle's power would drop, and repairs would be costly. I'd advise friends who frequently drive on highways to get into the habit of checking their AdBlue levels and not wait for the warning light to come on.
