Intended Use and Technical Characteristics

The presented injector is a part of the fuel system for Diesel engines, used in modern BMW N47N units, fitted in models such as the E90 LCI and F30 series. The injector nozzle's design has been developed for high operating pressures and precise fuel spray formation, which is crucial for efficient mixture combustion.

As an original BMW part, the injector maintains factory operating parameters, such as:

• stable fuel delivery across the full engine load range,
• appropriate spray pattern tailored to the N47N combustion chamber,
• compatibility with the factory engine control unit and injection maps.

Benefits of Using an Original BMW Injector Nozzle

Using an original injector in a BMW diesel engine allows for maintaining engine operating parameters close to factory specifications. In practice, this means:

• smoother engine operation at idle and under load,
• better throttle response due to correct fuel delivery,
• reduced smoke emissions and improved exhaust gas composition, provided the intake and exhaust systems are in good condition,
• lower risk of knocking and localized overheating in the combustion chamber.

For users, this translates not only to a higher level of driving comfort but also potentially lower fuel consumption, assuming other components of the injection and control systems are in good technical condition.

Item Condition and Service Application

This injector is categorized as used BMW injector nozzles, making it an attractive cost-effective alternative while maintaining original manufacturer specifications. This type of component is often chosen for:

• single cylinder repairs, when only one injector has been damaged,
• comparative diagnostics (test swapping injectors between cylinders),
• restoring factory configuration after previous unsuccessful fuel system modifications.

Before installation, it is recommended to perform standard workshop procedures, such as checking parameters on a test bench and verifying seal integrity, to match the injector's performance to the specific engine and its current condition.

Importance of Properly Functioning Diesel Injectors

Efficient injector nozzles are crucial for the longevity of the engine, especially in modern diesel units. Incorrect fuel delivery can lead to:

• accelerated wear of pistons and rings,
• clogging of the particulate filter,
• increased load on the turbocharger and exhaust system.

If you want to better understand the symptoms of wear and the consequences of neglect, it is worth reading the guide: diesel injector faults – symptoms, consequences, and diagnostics, which thoroughly discusses the topic of fuel injection system servicing.

Selection and Verification of Compatibility by OEM Numbers

When selecting an injector for a specific BMW model, it is essential to compare the OEM part number and interchangeable numbers with the vehicle's documentation or existing fuel system components. This helps to minimize the risk of incorrect fitment and avoid engine starting problems or control unit errors.
