• Purpose: AdBlue is a high-purity urea solution formulated specifically for modern diesel vehicles equipped with a Selective Catalytic Reduction (SCR) system.
• How it works: It is injected directly into the exhaust system upstream of the catalytic converter. There, it chemically reacts with harmful nitrogen oxide (\(NO_{x}\)) emissions, breaking them down into harmless nitrogen gas and water vapor before they exit the tailpipe.
• Safety Reminder: AdBlue is strictly an exhaust additive; it must never be poured directly into the diesel fuel tank. Always use the dedicated AdBlue filler port (typically located next to the diesel fuel cap, under the hood, or in the trunk area depending on your vehicle model
