Purpose and Function of the AdBlue Injector

The presented nozzle from the Injector Nozzles category works with the Diesel engine in the Transit Custom Mk8 2.0 EcoBlue model. Its task is to controlled atomization of the AdBlue solution in the exhaust system, ensuring the correct course of the reaction in the SCR catalyst and maintaining the vehicle's compliance with emission standards.

A properly functioning AdBlue injector contributes to:

• stable operation of the exhaust gas purification system under various engine loads,
• reduction of nitrogen oxide emissions under typical driving conditions,
• reduced risk of the vehicle entering limp mode due to AdBlue system errors.

Technical Characteristics and Compatibility

The AdBlue injector has been designed by Ford brand as a component structurally matched to the exhaust system and engine control of the Transit Custom Mk8 with the 2.0 EcoBlue unit. The appropriate nozzle geometry and mounting method allow for maintaining the correct spray angle and characteristics, which is crucial for the effectiveness of the SCR system.

The component has a dedicated OEM part number and associated replacement numbers, which facilitates verification of compatibility with a specific vehicle configuration. Before purchasing, it is advisable to compare the markings with the service documentation or the removed component to ensure full compatibility.

Product Condition and Installation Aspects

The offered AdBlue injector is a used part, allowing for economical repair of the exhaust gas system while maintaining the original manufacturer's specifications. This type of component is particularly useful in situations where the existing injector has become contaminated, mechanically damaged, or is generating errors in the engine control unit.

During installation, it is recommended to:

• thoroughly clean the mounting seat and the AdBlue supply lines,
• check the tightness of the connections after installing the component,
• perform adaptation or clear errors in the engine control unit using an appropriate diagnostic tester.

Benefits of Using a Functional AdBlue Injector

A functional AdBlue injector in the Ford Transit Custom Mk8 2.0 EcoBlue translates into a range of practical operational benefits:

• maintaining the correct operation of the SCR system without unwanted error messages on the dashboard,
• limiting AdBlue consumption through proper solution dosing,
• stable diesel engine performance without power drops resulting from limp mode,
• maintaining compliance with environmental requirements, which is important for technical inspections and fleet operations.

Diagnostics and Technical Knowledge

In case of problems with the AdBlue system – such as uneven engine operation, emission error messages, or increased solution consumption – it is worth consulting educational material describing typical symptoms and procedures for checking fuel injection system components.
