Technical Characteristics of the Injector

The presented injector belongs to the category of injector nozzles and is a component of the Diesel fuel system. It has been designed for 2.0 EcoBlue engines, where precise fuel spray formation and appropriate injection pressure are crucial. This allows for maintaining the correct combustion process, reducing smoke, and improving throttle response.

The injector works with a common rail system, where maintaining tightness, proper valve opening and closing characteristics, and fuel dose repeatability across different load ranges are important. A properly selected injector nozzle helps maintain stable idle speed and even operation of all cylinders.

Application and Compatibility

The component has been developed specifically for Ford vehicles with the 2.0 EcoBlue engine, particularly for models in the Transit Custom family. The use of the correct injector in this system directly impacts:

• maintaining proper power and torque across the entire RPM range,
• reducing fuel consumption through precise dosing,
• lowering exhaust emissions by correctly atomizing diesel fuel,
• reducing engine vibrations and uneven running under load.

Thanks to the assigned part numbers and interchangeable numbers, the injector can be easily verified with the existing system, which facilitates selecting the correct component during repair or replacement.

Condition, Service Application, and Benefits of Installation

The offered injector is a used part, making it an attractive service solution for users seeking an economical repair of the injection system while maintaining the original design. In many cases, installing a functional injector can eliminate typical wear symptoms, such as difficulty starting a warm engine, power loss, or increased exhaust smoke.

Replacing a worn injector nozzle with a functional component can bring tangible benefits:

• improved engine running smoothness – even combustion in every cylinder,
• stabilized fuel consumption – reduced excessive diesel fuel dosing,
• decreased risk of secondary damage (e.g., to the particulate filter) resulting from incorrect injection,
• more predictable vehicle behavior during acceleration and under load.

Diagnostics and Operation of the Injection System

With any intervention in the Diesel fuel system, it is worth paying attention to symptoms typical of worn injectors: uneven idling, knocking under load, increased fuel consumption, or engine control unit errors. It is good practice to combine injector replacement with checking operating parameters on a diagnostic bench.
