Injector Purpose and Role

The presented injector belongs to the category of injector nozzles and works with diesel engines used in Ford Fiesta MK6 and Ford Focus MK3 models with 1.5 and 1.6 TDCi units. Its function is to precisely atomize fuel in the combustion chamber, which is crucial for power, fuel consumption, and emissions.

A functional injector helps maintain:

• stable idle speed without jerking or misfires,
• smooth acceleration across the entire RPM range,
• optimal diesel combustion, leading to lower fuel consumption.

Construction and Operating Parameters

The injector is designed for operation in a Diesel fuel system, where operating pressures are high and manufacturing tolerances are very small. The precise design of the spray tip and its adaptation to the specific Ford application ensure:

• correct fuel spray pattern in the combustion chamber,
• repeatable injection quantities under various engine loads,
• efficient cooperation with the factory engine control unit without the need for software modifications.

This allows the injection system to maintain the characteristics intended by the vehicle manufacturer, which is important for both performance and the durability of the engine.

Benefits of Using an Original Ford Injector Nozzle

Using an original injector in a TDCi engine offers a range of practical benefits in daily operation:

• Improved engine running smoothness – reduced vibrations, knocking, and smoke during startup and acceleration.
• Stable combustion parameters – correct fuel doses help maintain appropriate temperature and pressure in the cylinders.
• Protection of other system components – proper injection reduces the load on the turbocharger, particulate filter, and exhaust system.
• Compatibility with factory design – a component designed specifically for Ford TDCi units, without the compromises typical of universal aftermarket parts.

For users who want to maintain their vehicle in accordance with factory specifications, choosing an original Ford injector nozzle is a technically safe and predictable solution.

Condition, Installation, and Injector System Diagnostics

The offered component is from the group of used original parts, allowing for access to an OEM component at a more favorable purchase cost. Before installation, standard workshop procedures are recommended, including checking for leaks, operating parameters on a test bench, and, if necessary, coding the injector in the engine control unit according to the vehicle manufacturer's procedure.

If your car exhibits symptoms such as difficult starting (hot or cold engine), increased smoke, loss of power, or uneven idling, it is worth consulting the guide diesel injector faults – symptoms, consequences, and diagnostics, which helps to better assess the condition of the injection system before deciding on component replacement.
