Purpose and Compatibility with N47N Engine

The presented BMW injector set for N47N engine has been designed for diesel units used in F20, F21, and F30 models in the 120d and 320d versions. The design of the injection system in these engines requires precisely selected injector nozzles to ensure proper fuel delivery, stable idling, and appropriate running characteristics under load.

The injection system in N47N engines operates under high pressure, making the use of the correct injector set crucial for:

• maintaining the correct mixture composition across the entire RPM range,
• reducing smoke emissions and improving exhaust gas quality,
• stable cold starts and starting with a warm engine.

Injector Nozzle Design and Characteristics

The product category is injector nozzles, which are components responsible for the precise atomization of diesel fuel in the combustion chamber. In BMW N47N engines, correctly selected nozzles influence:

• uniform fuel distribution within the cylinders,
• reduced engine noise due to the proper spray pattern,
• efficient fuel energy utilization, which translates to noticeable dynamics.

As components of a Diesel fuel system, the nozzles must work with a high-pressure pump and common rail, maintaining sealing and the correct opening time. Using the original BMW brand allows for maintaining factory engine operating parameters and reducing the risk of adaptation issues.

Performance Parameters and Installation Benefits

The offered injector set is designed for engines powered by Diesel fuel, meaning it is compatible with the factory configuration of 120d and 320d units. Using a complete set ensures consistent operation of all cylinders, without differences in fuel delivery between individual injectors.

• System Consistency – replacing the entire set reduces the risk of uneven running resulting from varying degrees of wear on individual nozzles.
• Improved Throttle Response – correct pressure and injection timing translate to a faster engine response to load.
• Potential Fuel Consumption Reduction – proper diesel atomization promotes more complete combustion.

The condition of the components is described as used, allowing for an economical restoration of the injection system's functionality while maintaining the original manufacturer's specifications.

Part Identification and Interchangeable Numbers

Manufacturer markings are crucial for correct selection for a specific vehicle. The product has an OEM part number, as well as assigned interchangeable numbers, which facilitates verification of compatibility with the BMW catalog and comparison with parts already installed in the vehicle. This allows for precise matching of the set to a specific N47N engine version in F20, F21, and F30 models.

The product description also includes data such as SKU and BMW brand, which further supports the identification and search process for the correct injector set in the store's catalog.
