Purpose and Compatibility

The injector set for BMW N47N is designed for modern diesel engines installed in the F10, F11, F20, F21, F30, and F31 series. The design of the injector nozzles is adapted to the characteristics of the N47N unit, which helps maintain correct combustion parameters, appropriate dynamics, and predictable throttle response.

Thanks to the use of original BMW technology, the injector set ensures proper fuel spray formation in the combustion chamber, which translates to smooth engine operation, reduced smoke, and improved idle and under-load performance.

Technical Characteristics of the Injection System

The presented set belongs to the category of Injector Nozzles and is intended for engines powered by Diesel fuel. Appropriately selected injection opening and closing parameters, as well as precise tip geometry, allow for maintaining:

• stable injection pressure across the entire load range,
• accurate fuel metering at low and high RPMs,
• optimal mixture atomization in the combustion chamber,
• consistent operation of all cylinders, which reduces vibrations and uneven engine running.

A properly configured injection system of this type contributes to maintaining the engine's factory performance while also helping to reduce fuel consumption and emissions, provided that other components of the fuel and intake system are in proper condition.

Practical Application and Benefits of Installation

The installation of the BMW injector set for the N47N engine is particularly recommended in situations where typical symptoms of injector wear appear, such as cold start difficulties, uneven idling, or power loss. In many cases, replacing the set can restore:

• smooth acceleration without jerking or power interruptions,
• stable idle speed without excessive vibrations,
• more predictable engine response to load,
• reduced excessive smoke during acceleration.

Due to the specifics of modern BMW diesel engines, correctly selected injector nozzles are crucial for engine durability, including protecting components such as the diesel particulate filter and the turbocharger.

Product Condition and Installation Aspects

The offered BMW injector set comes from the used parts segment, which is an attractive cost-effective solution compared to brand-new components. Before installation, professional diagnostics and, if necessary, injector adaptation in the engine control unit are recommended, in accordance with BMW service procedures.

When replacing the set of injector nozzles, it is worth paying attention to:

• cleanliness of the cylinder head seats and correct injector seating,
• use of appropriate seals and mounting components,
• checking other fuel system components (filter, lines, high-pressure pump),
• proper bleeding of the system after completing the work.
