Benefits and Functions: This Diesel Exhaust Fluid (DEF) injector is a crucial component in your vehicle’s Selective Catalytic Reduction (SCR) system, designed to reduce harmful nitrogen oxide (NOx) emissions and ensure compliance with strict emissions regulations. By precisely injecting DEF into the exhaust stream, it facilitates a chemical reaction that breaks down pollutants into harmless nitrogen and water vapor, contributing to a cleaner environment.
