A0001407878 Urea Pump is a high-precision AdBlue metering and conveying device that complies with the original factory standards. It is specifically designed for the SCR (Selective Catalytic Reduction) post-treatment system of commercial vehicles. The core of it is adapted to high-end commercial vehicle series models such as Mercedes-Benz. It is a key core component for ensuring that vehicles meet the emission regulations of National VI and European VI. Its core function is to accurately receive the command signals from the engine's electronic control unit (ECU), conduct high-pressure pressurization and precise metering of the urea water solution, and then atomize and spray it into the exhaust pipe. It undergoes an efficient reduction reaction with nitrogen oxides (NOx) in the catalytic converter to generate harmless nitrogen and water, achieving compliant exhaust pollutant emissions while ensuring the balance between engine power output and fuel economy.
