Purpose and Technical Characteristics

The presented injector system kit for BMW F20 and F30 with B47 engine is designed for diesel engines. The system's construction is adapted to the high operating pressures typical of modern diesel engines, which translates into precise fuel dosing, smooth engine operation, and reduced exhaust emissions.

The components included in the kit cooperate with the factory BMW engine control unit, allowing for the preservation of factory injection maps, correct dose corrections, and stable starts within a wide temperature range. Thanks to this, the system can be used both as a replacement for a damaged factory injector and as part of a comprehensive fuel system repair.

Category: BMW Injector Nozzles – Role in Engine Operation

The product belongs to the Injector Nozzles category, which are key components responsible for atomizing fuel in the combustion chamber. In BMW B47 engines, properly functioning nozzles contribute to:

• stable running quality at idle and under load,
• proper acceleration dynamics across the entire RPM range,
• maintaining fuel consumption at the level specified by the manufacturer,
• reducing smoke and vibrations resulting from improper atomization.

If a larger number of injection components need replacement, consider purchasing a complete kit, such as the BMW F20 F30 B47 120d 320d Injector System Kit, which facilitates maintaining consistent operating parameters for all cylinders.

Benefits of Using an Original Injector System

Using an original BMW injector system in a B47 diesel engine offers a range of practical operational benefits:

• Factory Fitment – compatibility with the vehicle's fuel and electrical systems without the need for modifications.
• Correct Pressure Parameters – the system is designed for specific control unit maps, facilitating adaptation and diagnostics.
• Consistent Operation of All Cylinders – uniform fuel dosing reduces the risk of local overheating and uneven running.
• Better Cooperation with Emission Control Systems – proper injection supports the operation of the particulate filter and EGR system.

Condition, Verification, and Service Application

The offered kit comes from a BMW vehicle and is intended for reinstallation in F-series diesel engines with the B47 unit, in the 120d and 320d versions. These types of components are frequently used in professional workshops specializing in modern diesel servicing, where compliance with factory specifications and correct adaptation in the diagnostic system are crucial.

Before installation, the standard service procedure is recommended: checking the fuel system for leaks, verifying operating parameters on a diagnostic tester, and – if necessary – performing injector adaptation according to BMW procedures. This will allow for the full utilization of the offered kit's potential and restore proper engine operation.
