The 22851845 urea pump is a high-precision AdBlue metering and conveying device specially developed for the SCR (Selective Catalytic Reduction) after-treatment system of commercial vehicles. It is mainly compatible with mainstream commercial vehicle series models such as Shaanxi Heavy Industry and Shaoguan Automobile. It is an indispensable core component for vehicles to achieve the compliance of the sixth emission standard. Its core function is to accurately receive the instructions from the engine electronic control unit (ECU), pressurize and precisely measure 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 exhaust gas in the catalytic converter, generating harmless nitrogen and water. This ensures the compliance of exhaust emissions while also balancing the engine power output and fuel economy.
