Adblue Environmental Fluid for Diesel Cars with Filling Cartridge

OverviewDiesel Exhaust Fluid (DEF), or often called AdBlue, is a combination of urea solution, which is stored in a separate tank in the car. Put simply, AdBlue is injected into the exhaust system to react with harmful nitrogen oxides (NOx), turning them into nitrogen (N₂) and water (H₂O). This technology has been used for several years in commercial trucks, and in recent years has seen increasing adoption in passenger car engines.
