Purpose and Compatibility with BMW N47N Engines

The injection system kit has been developed for BMW N47N diesel units used in the X1 E84 16d/18d and E90 LCI 316d/318d models. Proper adaptation to the architecture of these engines ensures:

• correct fuel spray formation in the combustion chamber, which translates to stable engine operation,
• maintenance of the torque characteristics intended for N47N engines,
• consistency with the factory fuel injection control strategy in load and cold start modes.

The system is configured for Diesel fuel, which is crucial for the correct operation of the injectors and other fuel system components.

Technical Characteristics of the Injection System Kit

The presented kit includes components responsible for precise diesel fuel metering into the cylinders. In practice, this means:

• controlled fuel dosage across the entire RPM range,
• stable fuel rail pressure (common rail) under typical operating conditions,
• proper fuel atomization, which reduces smoke and helps maintain appropriate exhaust emission parameters.

The kit comes from the BMW product line, which means maintaining the geometry, manufacturing tolerances, and operating characteristics in line with the vehicle manufacturer's specifications.

Condition, Verification, and Service Application

The components included in the kit are used, making them an attractive cost-effective alternative compared to new OEM parts. This type of solution is often chosen for:

• post-accident repairs, when a complete injection system replacement is necessary,
• routine maintenance for symptoms of injector wear or fuel pressure issues,
• restoring the factory configuration in vehicles where non-original fuel system modifications were previously applied.

It is always advisable to compare the OEM part number and interchangeable numbers with the vehicle's specifications before selecting the correct kit – all this information is available in the product's technical specifications section.

Benefits of Using Genuine BMW Injector Nozzles

Using genuine components from the injector nozzles category in BMW diesel engines translates into a number of practical benefits:

• smoother engine operation at idle and under load,
• better throttle response due to proper fuel metering,
• reduced risk of excessive smoke and particulate filter issues,
• maintenance of factory fuel consumption parameters, which contributes to the durability of the N47N unit.

In case of doubts about the condition of existing injectors or symptoms such as uneven running, power loss, or increased fuel consumption, it is worth consulting the guide: Diesel Injector Faults – How to Recognize Them and What Are the Dangers of Neglecting Them. The article helps assess when replacing the injection system kit is justified.
