Purpose and Function in the Injection System

The injector mount in N47 and B47 engines is responsible for securely pressing the injector into its seat in the cylinder head and maintaining the correct position of the spray tip. This ensures the injection system maintains proper sealing, and the fuel dose is delivered at the correct angle and pressure.

In BMW diesel engines, even minor deviations in injector position can lead to:

• uneven engine idle,
• reduced performance and sluggish throttle response,
• increased fuel consumption and exhaust smoke,
• accelerated wear of injector seats and seals.

A properly selected mount is therefore an essential component for any work on the injection system, especially after injector removal or refurbishment.

Compatibility with BMW Models and Diesel Engines

The presented mount is designed for selected BMW 1, 3, and 5 Series models equipped with N47 and B47 diesel engines. This includes popular body styles such as hatchback, sedan, and wagon, allowing for broad application in vehicles used for both private and fleet purposes.

Thanks to the use of an OEM solution, the mount is compatible with factory diesel injectors, maintaining original geometry and mounting parameters. This is important for servicing modern diesel engines where assembly tolerances are very strict.

Benefits of Using an Original Injector Mount

Choosing an original injector mount for BMW offers a range of practical service and operational benefits:

• Factory Fitment – a component designed for a specific cylinder head and injector design, requiring no modifications.
• Stable Injector Retention – reduces the risk of micro-movements that can lead to exhaust blow-by at the injector seat.
• Supports Proper Diesel System Operation – maintains the correct angle and seating depth of the injector tip.
• Hassle-Free Installation – can be used in standard service procedures, in accordance with BMW documentation.

When combined with the correct tightening torque and new seals, such a mount helps maintain stable diesel engine operating parameters and reduces the risk of costly future repairs.

Item Condition and Service Application

The offered BMW injector mount is a used part, removed from a vehicle, and intended for users and workshops seeking a proven service solution for diesel injection systems. These types of components are often replaced during:

• injector refurbishment or replacement,
• sealing issues around injector seats,
• preventive maintenance on high-mileage vehicles.

Selecting the correct mount based on the OEM part number or interchangeable numbers ensures compliance with original BMW documentation and avoids installation problems.

Technical Support and Educational Materials

When working with diesel injection systems, it is beneficial to be aware of common signs of wear and damage.
