New Urea Injector Opel Psa 1.6 HDi

The AdBlue injector with OE code 9802763880 is a key component of the SCR (Selective Catalytic Reduction) system used in 1.6 BlueHDi and 1.6 CDTi diesel engines of PSA group and Opel vehicles. Its function is to ensure precise dosing of the urea solution into the exhaust gases, contributing to the reduction of nitrogen oxides (NOx) to comply with Euro 6 regulations.

Technical characteristics of the urea injector 9802763880

The OE injector 9802763880 is designed to operate in high-temperature environments and under chemically aggressive conditions, such as those found in the exhaust post-treatment systems of modern diesel engines.

DIPA offers a range of original and equivalent-quality aftermarket spare parts.

Main specifications

• Original code: 9802763880
• Component type: electronically controlled urea injector
• Power supply: 12V – 2-pin connector
• Materials: stainless steel and polymers resistant to AdBlue
• Mounting: direct on the SCR catalyst, via flange or threaded fitting

The injector body is designed to provide resistance to crystallization, perfect sealing and long operational life.

Function of the AdBlue injector in the SCR system

The AdBlue injector is an active part of the SCR system, whose function is to reduce nitrogen oxides in the exhaust gases of diesel engines. It receives commands from the engine control unit to dose a specific amount of urea solution (AdBlue) based on temperature, gas flow and engine load.

Main tasks:

• Inject AdBlue in atomized form into the exhaust duct
• Allow the chemical reaction NOx → N₂ + H₂O within the SCR catalyst
• Ensure a precise mixture to avoid reagent excesses or shortages
• Work in synergy with upstream and downstream NOx and temperature sensors

Proper atomization of AdBlue is essential for treatment effectiveness and catalyst longevity.

DIPA recommends always checking compatibility based on the specific engine code and the vehicle identification number (VIN).

Typical faults

• Fluid crystallization: nozzle blockage due to evaporation and formation of solid deposits
• Injector body corrosion: due to chemical reactions between AdBlue and unsuitable materials
• Electrical failure: solenoid malfunction or loss of command signal
• Leaks at the fitting or seal: caused by high pressures and temperatures
• Poor atomization: alteration of the spray cone leading to SCR system inefficiency

Recognizable symptoms

• Illumination of the engine or AdBlue warning light
• Messages such as "Check emissions system"
• Emergency mode activated with limited power
• Increased emissions detected at inspection

Conclusions

The AdBlue injector OE 9802763880 is a key component of the exhaust gas post-treatment system in 1.6 BlueHDi and 1.6 CDTi diesel engines. Its correct operation ensures compliance with Euro 6 emissions standards and the full functionality of the vehicle.
