Set Purpose and Characteristics

The injector set for BMW 320d N47N has been designed for precise fuel metering in the diesel engine. Appropriately selected injector nozzles ensure proper atomization of diesel fuel, which translates into stable engine operation, smooth running, and reduced smoke under load.

The components included in the set are from the original BMW line, which helps maintain the factory parameters of the fuel system. Thanks to this solution, typical operational problems related to injector wear in diesel engines can be effectively reduced.

Technical Specifications and Compatibility

The presented set belongs to the injector nozzles category and is intended for an engine powered by diesel fuel. The design of the injection system in this engine requires precisely selected components, therefore using a set tailored to the specific N47N variant facilitates maintaining correct pressures and injection times.

The product has a dedicated manufacturer part number and a set of interchangeable numbers, which facilitates compatibility verification by OEM identifiers. This allows a mechanic or user to easily check compatibility with a specific configuration of the facelifted BMW 3 Series without the need to modify the fuel system.

Condition, Application, and Benefits of Installation

The injector set is offered as a used part, which represents a reasonable compromise between repair cost and maintaining the original manufacturer's specifications. This type of solution is often chosen for comprehensive fuel system servicing when several components need to be replaced simultaneously.

Properly selected injector nozzles in the N47N engine help to:

• stabilize idle operation and reduce engine vibrations,
• improve throttle response through correct fuel metering,
• reduce the risk of excessive smoke during acceleration and under load,
• maintain proper combustion, which contributes to the protection of the particulate filter and other exhaust system components.

For diesel engines, regular inspection and potential replacement of injectors are crucial for the durability of the engine, therefore using a complete set tailored to a specific BMW model is a practical service solution.

Diagnostics and Operation of the Injection System

Before installing the injector set, it is advisable to conduct thorough diagnostics of the fuel system to confirm the cause of the engine's malfunction. Symptoms such as uneven running, power loss, or increased fuel consumption are often related to injector nozzle wear, but can also result from other system components.

If you want to better understand the typical symptoms of injector wear and the consequences of neglecting them, refer to the article: Diesel Injector Faults – How to Recognize Them and What Neglecting Them Entails. This is a practical addition to your knowledge when planning a repair or replacement of the injector set.
