Techinical Info

The AdBlue pump DAF part number OE 2871880 is a urea/SCR dosing module for DAF Euro 6 commercial vehicles. It is a complete unit of the Denoxtronic 2.2 24 V type, which integrates in a single housing the hydraulic components for AdBlue management (suction, filtration, pressurization, delivery), the main sensors and the control electronics.

The module's task is to draw the urea solution from the tank, bring it to pressure and send it to the SCR injector mounted on the exhaust line, ensuring the correct dosing of AdBlue necessary for selective catalytic reduction of NOx and compliance with Euro 6 regulations for heavy-duty diesel engines.

Technical specifications

  • Type: AdBlue dosing pump for SCR system
  • System: Denoxtronic 2.2 family for commercial vehicles
  • Supply voltage: 24 V DC
  • Application: Euro 6 exhaust aftertreatment systems with SCR catalyst
  • Integrated functions: suction, filtration, pressurization, pressure control and delivery of AdBlue to the injector

DIPA can intervene to overhaul these components thanks to its experience and expertise.

Functions

  • Drawing AdBlue from the tank via a suction line and dedicated filter
  • Pressurization of the fluid in the delivery circuit towards the SCR injector, via electric motor and integrated pumping assembly
  • Measurement and regulation of AdBlue pressure via an internal sensor and closed-loop control by the module's electronics
  • Accurate dosing of the amount of AdBlue based on engine load, air mass, temperature and signals from the NOx sensors upstream and downstream of the catalyst
  • Management of filling and circuit purge phases, to reduce the risk of urea crystallization in the pipes during downtime or low temperatures
  • Self-diagnostic functions for pump motor, pressure sensor, internal valves and power supply, with fault reporting to the engine/SCR control unit
  • Communication with the engine ECU and SCR control unit via the vehicle network, exchanging operating parameters and fault codes

Model applications

  • DAF XF/XG Euro 6 (road tractors with MX engines)

Common faults

  • Pump electric motor failure
  • AdBlue crystallization inside internal passages and pipes
  • Warning light illumination on the dashboard

Final conclusions

The AdBlue pump DAF OE 2871880 is a critical component for the correct operation of the SCR system on DAF Euro 6 vehicles, in particular the XF/XG ranges.
