DEF Doser Pump Cummins 4388105 | A060H209, A052Y605
High-precision DEF doser pump for Cummins X12 and X15 engines, ensuring optimal SCR performance and emissions compliance.
Description
High-Performance DEF Doser Pump for Cummins Engines
The Cummins 4388105 Doser Pump is a critical component of the Selective Catalytic Reduction (SCR) system in modern heavy-duty diesel engines. This pump is responsible for precisely injecting Diesel Exhaust Fluid (DEF), also known as AdBlue, into the exhaust stream. By reacting with nitrogen oxides (NOx) in the presence of a catalyst, it converts harmful pollutants into harmless nitrogen and water vapor, ensuring your vehicle meets stringent environmental regulations.
Key Features and Benefits
- Precise Dosing: Integrated with the engine’s Electronic Control Unit (ECU) to deliver the exact amount of DEF based on real-time engine load and exhaust temperature.
- Durable Construction: Built with high-quality materials to withstand the harsh operating conditions of commercial trucking.
- Emissions Compliance: Helps maintain the efficiency of the aftertreatment system, reducing NOx emissions and avoiding engine derate conditions.
- Engine Efficiency: Proper DEF injection supports optimal exhaust flow and can contribute to improved fuel economy and component longevity.
