DESCRIPTION
The Doser Pump (part number 5375481) is a component found in modern diesel trucks equipped with Selective Catalytic Reduction (SCR) systems. Its main function is to supply the Diesel Exhaust Fluid (DEF) required for the SCR process to occur. The pump draws DEF from the vehicle's storage tank and delivers it through a high-pressure line to the injector, where it is sprayed into the exhaust stream. This interaction with hot exhaust gases causes a chemical reaction that reduces harmful nitrogen oxides emissions into harmless nitrogen and water vapor. The Doser Pump plays a critical role in ensuring compliance with emission standards and maintaining optimal engine performance.
