A Diesel Exhaust Fluid (DEF) doser injector is a critical component in the selective catalytic reduction (SCR) system of modern diesel engines. It injects DEF, a solution of urea and deionized water, into the exhaust stream. The DEF reacts with nitrogen oxides (NOx) in the exhaust, converting them into harmless nitrogen and water vapor, thereby reducing harmful emissions and helping the engine comply with stringent environmental regulations.
