Purpose and Function in the AdBlue System
The described AdBlue injector nozzle for Citroën Relay III operates in close proximity to the additive tank, controlling the dose of the agent dispensed into the exhaust system. A correctly functioning injector ensures:
- stable additive dosing across a wide range of engine loads,
- maintaining the efficiency of the exhaust purification system according to the manufacturer's specifications,
- reducing the risk of the engine entering limp mode due to AdBlue system errors.
This element belongs to the category of injector nozzles, meaning it is a precision part operating under demanding temperature and chemical conditions, thus its condition is crucial for the entire system.
Construction and Characteristics of the Element
The AdBlue injector nozzle in the Citroën Relay III is integrated with a sensor operating near the additive tank, allowing for real-time monitoring of the system's operating parameters. This enables the vehicle's control unit to:
- accurately control the dose of injected additive,
- respond to system operational deviations by generating appropriate service messages,
- maintain compliance with exhaust emission standards for the specific engine variant.
The solution used by Citroën in this model is structurally adapted to the Relay III's fuel and exhaust system, which facilitates installation and reduces the risk of compatibility issues.
Condition, Origin, and Practical Application
The offered injector nozzle comes from the Citroën OE line, meaning it is an original part designed specifically to work with the factory AdBlue system in the third-generation Citroën Relay. The product is used, allowing for economical vehicle repair while maintaining compatibility with the factory solution.
In practice, installing such an element is particularly recommended when the vehicle displays:
- AdBlue or fuel additive system error messages,
- starting problems or power loss related to the exhaust purification system's operation,
- incorrect additive level readings or frequent transitions into limp mode.
Diagnostics and Technical Knowledge
Before replacing the injector nozzle, it is advisable to conduct thorough system diagnostics to confirm the source of the fault.
