AdBlue is a clear, colorless, and non-hazardous solution used to reduce nitrogen oxide (NOx) emissions in the exhaust gases of vehicles equipped with Selective Catalytic Reduction (SCR) technology. AdBlue is a solution of urea (32.5%) and deionized water (67.5%), specifically designed to enhance engine performance without affecting the vehicle’s overall performance. It is primarily used in trucks, buses, commercial vehicles, and some passenger cars that are equipped with SCR technology to meet Euro 6 emission standards.
