Urea Injector Psa Opel HDi 9801187080

The AdBlue injector with OE code 9801187080 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 the 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 9801187080

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

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

Main specifications:

• Original code: 9801187080
• Component type: electronically controlled urea injector
• Power supply: 12V – 2-pin connector
• Materials: stainless steel and AdBlue-resistant polymers
• Mounting: direct on the SCR catalyst, via flange or threaded fitting

The injector body is designed to ensure 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 to occur inside the SCR catalyst
• Ensure a precise mixture to avoid excesses or shortages of reagent
• Work in synergy with NOx and temperature sensors upstream and downstream of the catalyst

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

DIPA recommends always checking compatibility based on the specific engine code and chassis number.

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 from the fitting or gasket: caused by high pressures and temperatures
• Incorrect atomization: alteration of the spray cone resulting in SCR system inefficiency

Recognizable symptoms

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

Conclusions

The AdBlue injector OE 9801187080 is a key component of the exhaust gas post-treatment system in 1.6 BlueHDi and 1.6 CDTi diesel engines. Its correct functioning ensures compliance with Euro 6 emission regulations and the full operability of the vehicle.
