Purpose and Function of the AdBlue Injector Nozzle

The AdBlue injector nozzle in a Ford Transit Custom running on Diesel fuel is part of the Selective Catalytic Reduction (SCR) system. Its task is to evenly atomize the AdBlue solution into the exhaust stream, ensuring that the chemical reaction in the catalyst proceeds stably and in compliance with emission standards. A properly functioning nozzle contributes to:

• maintaining the efficiency of the exhaust gas purification system and reducing the risk of the vehicle entering limp-home mode,
• stable operation of the diesel engine under varying loads and different road conditions,
• correct AdBlue dosing, which translates to controlled fluid consumption and lower operating costs.

Technical Characteristics and Compatibility

The offered nozzle belongs to the category of injector nozzles and was developed by the manufacturer for integration with the factory exhaust system of the Ford Transit Custom. Using an original Ford OE part ensures:

• compatibility with the factory SCR system operating characteristics,
• correct spray pattern geometry of the AdBlue solution in the exhaust channel,
• seamless cooperation with the control electronics responsible for the injection dose and timing.

This allows the nozzle to be used both as a replacement part in case of failure and as part of preventive maintenance for the diesel engine's exhaust gas purification system.

Condition of the Part and Benefits of Choosing a Used Part

The presented AdBlue injector nozzle is offered as a used part, providing a sensible compromise between purchase cost and maintaining near-factory performance. In practice, this means:

• lower cost of AdBlue system servicing compared to a new component,
• the ability to quickly replace a damaged nozzle without the need for system modifications,
• preserving the original system design, which facilitates diagnostics and subsequent service.

Choosing a tested, used nozzle is particularly beneficial for fleet vehicles and high-mileage units where repair economy is important while maintaining proper exhaust emission system operation.

Operation, Diagnostics, and Technical Support

Symptoms of wear or malfunction of the AdBlue injector nozzle may include exhaust emission system error messages, increased AdBlue consumption, or the vehicle entering a limited power mode. In such situations, an expert guide on diagnosing injection systems in diesel engines will be helpful: diesel injector faults – symptoms, consequences, and diagnostics. This guide helps to better understand the relationships between the operation of fuel injectors, the SCR system, and the overall condition of the powertrain.
