Application and Characteristics of the BMW B47 Injection System

The presented injection system for BMW F20 and F30 LCI 120d / 320d B47 has been designed to meet the requirements of modern direct-injection common rail diesel engines. It is responsible for precise high-pressure fuel delivery, which translates to correct power, flexibility, and reduced engine smoke and noise.

This component belongs to the Injector Nozzles group, meaning its key task is to form the correct fuel spray pattern in the combustion chamber. A properly selected injection system allows for maintaining the factory operating parameters of the B47 engine, reducing the risk of knocking, and ensuring smooth idle operation.

Benefits of Using an Original Injection System

Using an original solution from the BMW Injector Nozzles group in the B47 engine offers a range of practical operational benefits:

• Stable Engine Operation – correct fuel doses across the entire RPM range reduce jerking, fluctuating idle, and starting problems.
• Optimal Dynamics – maintaining the factory performance of the 120d / 320d unit, without power drops due to incorrect injection.
• Exhaust Emission Control – proper fuel atomization supports the exhaust gas treatment system and helps meet emission standards.
• Improved Running Smoothness – reduction of excessive smoke, knocking, and metallic noises typical of worn injectors.

This type of injection system is particularly important in B47 engines, where fuel metering precision directly impacts the durability of the engine, turbocharger, and ancillary components.

Condition, Origin, and Technical Aspects

The offered component is a used BMW injection system, sourced from disassembly, which allows for economical repair compared to purchasing a brand-new set. At the same time, it maintains compliance with the manufacturer's factory specifications, facilitating installation and integration with the existing fuel system and engine control unit.

For workshops and users, it is important that the product has an assigned OEM part number and corresponding interchangeable numbers, enabling unambiguous identification in service catalogs and parts selection systems. This allows for precise verification of compatibility with a specific version of the BMW F20 or F30 LCI with the B47 engine.

Injection System Diagnostics and Prevention

In cases of symptoms such as difficult starting (hot or cold engine), power loss, increased fuel consumption, or smoking, one of the first components to check is the diesel engine injector nozzles. Improper injector operation can lead to accelerated wear of pistons, bearings, the turbocharger, and the particulate filter.
